Sort in a tableview

Hello,
my internal table has 10 records which are displayed in a Tableview. The user has the option to sort the information (asc/desc) according to the column which he wishes. Then he has to select a line to display the data of this record. It works perfect if there´s no sort but if the user sorts the table, the internal table is not sorted.
If the user selects record 3 on the Tableview, that record could be Nr. 9 in my internal table. How can I sort at the same time my internal table ??
Thanks
 Coding
<htmlb:tableView id = "result_mat"
 selectionMode = "SINGLESELECT"
 headerText = "<%= otr(SOTR_VOCABULARY_BASIC/RESULT) %><%= otr(SOTR_VOCABULARY_BASIC/LIST) %>"
 headerVisible = "true"
 emptyTableText = "<%= otr(/SIE/AD_ZDXD0001/SUCHEF4) %>"
 sort = "SERVER"
 visibleRowCount = "12"
 columnDefinitions = "<%=columns%>"
 onRowSelection = "EventRowSelection"
 table = "<%= tab_material %>" />

you can handle it in two ways, to have sort and also reading the right selected record from the itab.
option1. instead of using SORT = "SERVER" use "APPLICATION" in this case you have to manually handle the sort.
code sample for the same.
page attributes:
sort_element TYPE STRING
sort_event TYPE STRING
s_event TYPE CHAR1
layout
<% if sort_event is initial .
move: 'A' to sort_event .
endif .
if sort_event eq 'A' .
if not sort_element is initial .
sort <outtab> ascending by (sort_element).
else .
sort <outtab> ascending .
endif .
elseif sort_event eq 'D' .
if not sort_element is initial .
sort <outtab> descending by (sort_element).
else .
sort <outtab> descending .
endif .
endif .
 %>
 <htmlb:tableView id = "test"
 headerVisible = "false"
 footerVisible = "true"
 onHeaderClick = "<%= sort_event %>"
 table = "<%= <outtab> %>"
 iterator = "<%= grid_iterator %>"
 columnDefinitions = "<%= col_control_tab %>"
 width = "100%"
 columnHeaderVisible = "true"
 sort = "APPLICATION" />
oninputprocessing.
CLEAR s_event .
CLASS cl_htmlb_manager DEFINITION LOAD.
DATA: event TYPE REF TO cl_htmlb_event .
data: tv type ref to cl_htmlb_tableview.
data: tv_data type ref to cl_htmlb_event_tableview.
event = cl_htmlb_manager=>get_event( request ).
IF event->event_type EQ cl_htmlb_event_tableview=>co_header_click .
s_event = 'Y' .
tv ?= cl_htmlb_manager=>get_data(
 request = runtime->server->request
 name = 'tableView'
 id = 'test' ).
if tv is not initial.
 tv_data = tv->data.
endif .
sort_element = tv_data->column_key .
if event->SERVER_EVENT eq 'A' .
sort_event = 'D' .
elseif event->SERVER_EVENT eq 'D' .
sort_event = 'A' .
endif .
ENDIF .
option 2:
use keyColumn = "<itab key filed name in uppercase>"
<htmlb:tableView id = "test"
 design = "ALTERNATING"
 headerVisible = "true"
 headerText = "List of Low Value Assets"
 table = "<%= det_tab %>"
 width = "100%"
 columnHeaderVisible = "true"
 sort = "SERVER"
 filter = "SERVER"
 filterButtonText = "Go"
 columnDefinitions = "<%= col_control_tab %>"
 keepSelectedRow = "TRUE"
 keyColumn = "KEY_COL"
where key_col is a column in the itab which holds the concatenated value of key fields.
for example if your itab has say order no., item number, value and the key is order number and item number.
concatenate them and place it in the key_col field and dont show that in display mode.
and in oninputprocessing you can read the selected row value like below.
if event->event_type eq cl_htmlb_event_tableview=>co_row_selection .
data: tv type ref to cl_htmlb_tableview.
tv ?= cl_htmlb_manager=>get_data(
 request = runtime->server->request
 name = 'tableView'
 id = 'test' ).
if tv is not initial.
 data: tv_data type ref to cl_htmlb_event_tableview.
 tv_data = tv->data.
 if tv_data->selectedrowindex is not initial.
 data: row like line of <itab> .
either you can use this index to read the itab or
tv_data->selectedrowkey will hold the selected rows key_col value which you can use to read the itab.
Hope this helps.

Bug or feature: TableView sorts the underlying list?

that's at least highly unexpected - all variants of table sorting I know, support some kind of sortedView on top of the user model (either by a framework outside of the table, as GlazedList, or internal as core swing).
Is it a not-yet-done feature or yet another variant of leaving the hard stuff to the user dev?

This is by-design. We consider the items list in the TableView to be the view model - clicking on a column results in the view model being sorted.
There are ways around this. If you provide a TransformationList (e.g. SortedList) wrapped around an ObservableList, the TableView will sort the SortedList, leaving the underlying ObservableList unsorted and still available via SortedList.getDirectSource() or getBottomMostSource() (depending on how many layers of wrapping you have).that's exactly what I keep complaining about:
- framework handles the trivial stuff: it simply pushes a comparator into a sortable list is or lets collections.sort do the work
- developers are left with the harder parts like index mapping
Actually, the framework is hit by those missing harder parts as well:
- SortedList freaks out on mutable elements, basically because the internal index mapping is not optimal (http://javafx-jira.kenai.com/browse/RT-14965)
- Selection synch is broken when sorting/filtering (and TableView taking the extreme easy way out in clearing ... tseee), don't have a report handy, but know that you are aware of the issue : - )
- no way to "unsort" a TableColumn (http://javafx-jira.kenai.com/browse/RT-15166) in the general case. Even for a SortedList, that would involve to restore the original comparator (instead of leaving the TableColumnComparator in place)

Getting filtered values from TableView

Hi,
We have a TableView whose columns can be sorted. Iwant to select a few rows and make the selected rows editable in another page.
If it is a unsorted/unfiltered TableView, am able to do it as the ABAP Internal Table and the TableView are the same in terms of record index positions. But am facing problem after i sort/filter the TableView because now the index of the TableView are different from the index of the ABAP Internal Table present in server.
Anybody who has dealt with this problem earlier and can guide us.
Thanks,
Chathia.

How do i change the cursor on a jtable header when clicked for sorting?

here is my question, how do i change the cursor on a jtable header when I click the header for sorting?
I think it is suppose to be in the fragment of code where the header listener is implemented for sorting, but I'm not quite sure what is the exact component that holds everything so that i can change the cursor...
below is what I've tried, but it doesn't seem to work... thank you
public void addMouseListenerToHeaderInTable(JTable table) {
final TableSorter sorter = this;
final JTable tableView = table;
tableView.setColumnSelectionAllowed(false);
MouseAdapter listMouseListener = new
MouseAdapter() {
public void mouseClicked(MouseEvent e) {
TableColumnModel columnModel =
tableView.getColumnModel();
int viewColumn =
columnModel.getColumnIndexAtX(e.getX());
int column =
tableView.convertColumnIndexToModel
(viewColumn);
System.out.println("column = "+column);
if (e.getClickCount() == 1 && column != -1) {
System.out.println("Sorting ...");
Cursor oldCursor =
tableView.getRootPane().getCursor();
System.out.println("oldCursor.getType()
= "+oldCursor.getType());
if (oldCursor.getType() !=
Cursor.WAIT_CURSOR){
JComponent parentPane =
tableView.getRootPane();
parentPane.getContentPane().setCursor
(new Cursor(Cursor.WAIT_CURSOR));
parentPane.setCursor(new Cursor
(Cursor.WAIT_CURSOR));
Cursor newCursor =
parentPane.getCursor();
System.out.println("newCursor.getType
() = "+newCursor.getType());
int shiftPressed = e.getModifiers(
&InputEvent.SHIFT_MASK;
boolean ascending = (shiftPressed == 0);
//System.out.println("tableView.getRootPane()
is "+tableView.getRootPane().getRootPane());
sorter.sortByColumn(column, ascending);
tableView.getRootPane().setCursor(new Cursor
(Cursor.DEFAULT_CURSOR));
//System.out.println("Done sorting");
JTableHeader th = tableView.getTableHeader();

Hi,
Try setting the cursor for the table header.
table.getHeader().setCursor(Wait_Cursor);

SORT in a BSP applicaiton doesnt work

Hi Experts,
In my BSP Application , I use a table and below is code for the
 <htmlb:tableView id = "WRKLST"
 headerText = "My Worklists"
 headerVisible = "true"
 design = "alternating"
 visibleRowCount = "<%= RowCount%>"
 filter = "SERVER"
 sort = "server"
 fillUpEmptyRows = "TRUE"
 emptyTableText = "No entries found"
 onHeaderClick = "MyEventHeaderClick"
 onRowSelection = "rowselection"
 selectionMode = "multiselect"
 table = "<%= IT_WRKLIST %>"
 iterator ="<%= iterator%>" >
But the sort is not very efficient. ie., it always sort only on the first click of the header 's. and also it sort only on key field.
Can anybody suggest me an option , so that on every click it sorts ascending / descending based on the click of the header.
ie., If the user clicks on 'Partner Name' , it should sort the table content based on Partner name and if the click on 'Priority', it should sort on priority.
Please suggest.

Dear Shiny
Please check these posts.
I think you will need to sort the table yourself and then have the page refreshed.

How to set filters to a Result view

Hi All,
 How to set filters to a result view in web UI.
Thanks & Regards
Nitish.

Hi Nitish Kumar,
if you want to sort the table fields like ascending , Descending create one event ex: eh_on_sorting.
in that get the event using thtmlb_event. then check whether sorting is necessary or not.
then get the name of column to be sort by using tableview->column_key.
based on that arrange the field ascending or descending using tableview->column_sort_directin.
ascending or descending.
then sort the collection using collection_wrappor->sort( lv_attrname .. etc).
here is the sample code..
data: lv_bo type ref to if_bol_bo_property_access,
 lv_thtmlb_tableview type ref to cl_thtmlb_table_view,
 lv_attr_name type name_komp,
 lv_sort_order type char1,
 lv_stable type abap_bool value abap_false.
 try.
 lv_thtmlb_tableview ?= iv_htmlb_event_ex.
 catch cx_sy_move_cast_error.
 exit.
 endtry.
 if lv_thtmlb_tableview is bound.
* check whether its realy a sorting event
 check lv_thtmlb_tableview->event_type = cl_thtmlb_table_view=>co_header_click.
* get name of column to be sorted
 lv_attr_name = lv_thtmlb_tableview->column_key.
 check lv_attr_name is not initial.
* get sorting direction
 case lv_thtmlb_tableview->column_sort_direction.
 when 'U'.
 lv_sort_order = cl_bsp_wd_collection_wrapper=>sort_ascending.
 when 'D'.
 lv_sort_order = cl_bsp_wd_collection_wrapper=>sort_descending.
 when others.
 return.
 endcase.
* sort
 try.
 me->collection_wrapper->sort( iv_attr_name = lv_attr_name
 iv_sort_order = lv_sort_order
 iv_stable = lv_stable
* IV_SORT_CALLBACK =
 catch cx_crm_cic_parameter_error.
* could be a renamed attribute or field which does not belong to the collection
 endtry.
* in case of single selection restore the selected row index
 if me->selection_mode = selmode_single
 or me->selection_mode = selmode_lineedit.
 if me->selected_index <> '0'.
 me->selected_index = me->collection_wrapper->get_current_index( ).
 endif.
 endif.
 else.
 exit.
 endif.

JTable - make column headers clickable

Hi all
I have a JTable, and now I want to sort by column. I've actually got the column sorting working using menu items, but how can I make my column header clickable, and where do I add an actionListener to?

    public void addMouseListenerToHeaderInTable(JTable table) {
        final JTable tableView = table;
        tableView.setColumnSelectionAllowed(false);
        MouseAdapter listMouseListener = new MouseAdapter() {
                    public void mouseClicked(MouseEvent e) {
                        TableColumnModel columnModel = tableView.getColumnModel();
                        int viewColumn = columnModel.getColumnIndexAtX(e.getX());
                        int column = tableView.convertColumnIndexToModel(viewColumn);
                        if (e.getClickCount() == 1 && column != -1) {
                            int shiftPressed = e.getModifiers() & InputEvent.SHIFT_MASK;
                            boolean ascending = (shiftPressed == 0);
                            // sort
        JTableHeader th = tableView.getTableHeader();
        th.addMouseListener(listMouseListener);

TableView - How to update a running balance column after any other column in the view is re-sorted

To keep this simple and to illustrate a problem that I am trying to solve let's say we have
a domain class that contains an income per day.
This class has two persistent properties - populated from a database table - date and income.
And there is one transient property - running balance - that shows the accumulated income
starting from the first record. This property is not persisted and it is used only to show
the running/accumulated income in a table view.
This domain object is shown in a table view with three columns:
 - date
 - income
 - running balance
The first two columns - date and income - are sortable. When the user clicks on the column
heading these can will be sorted in ascending or descending order. The running balance
column needs to reflect this change and be correctly updated.
So the question is : how would you implement the running balance update after the data in
the table has been updated by the user?
Take 1)
=============
The obvious approach is to use "setOnSort" method to consume the SortEvent event and re-sort the
data but the sort-event does not contain any useful information that would tell from which column
the sort event originated.
Take 2)
=============
Found a possible solution:
 - TableView.getSortOrder() returns a list that defines the order in which TableColumn instances are sorted after the user clicked one or more column headings.
 - TableColumn.getSortType() returns the sort type - ascending/descending.
 - This info can be used in the TableView.setOnSort() event handler to re-sort the data and update the balance at the same time.
Take 3)
=============
When the TableView.setOnSort() event handler is called the data is already sorted therefore the only thing that needs to be done is to update the running balance.

I think I understand what you're trying to do. If I've missed it, apologies, but I think this will provide you with something you can work from anyway.
I would listen to the data instead of watching specifically for sorting. This will be much more robust if you add new functionality later (such as adding and removing rows, editing the data that's there, etc).
Specifically, for the runningBalance column, create a cellValueFactory that provides a DoubleBinding; this binding should listen for changes to the data and compute the value by running through the table's items up to the point of the item for which it's displaying the value. (Hope you can untangle that sentence.)
Example. The important part is the cellValueFactory for the cumulativeAmountCol. I guess I should mention that you shouldn't try this exact approach with very large tables as the performance might be pretty bad (computations of the order of n x m on changing data, where n is the number of rows in the table and m is the number of visible rows in the table).

TableView: sort="server" with iterator-generated cell content

I have an htmlb:tableView that uses an iterator and sort ="SERVER".
In one of the columns, I change the text that is displayed a little bit in RENDER_CELL_START of the iterator.
DATA lr_text TYPE REF TO cl_htmlb_textview.
FIELD-SYMBOLS <fs_row> LIKE LINE OF me->t_bla.
ASSIGN p_row_data_ref->* TO <fs_row>.
CASE p_column_key.
 WHEN 'MY_FIELDNAME'.
 CREATE OBJECT lr_text.
 lr_text->id = p_cell_id.
 lr_text->text = me->get_name( <fs_row>-id ).
 p_replacement_bee = lr_text.
Now, if I click on the sort icon of the column, the table is sorted by the field 'MY_FIELDNAME', but not by the actual content of the column.
How would I achieve that?

this sounds almost possible.
I cannot write the new value into the original field of the table though, because I cannot be sure that the datatypes fit to each other and because I stil need the original values.
But I could of course add some more fields to the table structure (which I would not like so much), loop at the table before I use it in the tableView and write the new values into these fields.
Then, I wouldn't even need RENDER_CELL_START at all.

Any help would be greatly apprciated and rewarded...

Hi Don,
be aware that after the method onHeaderClick(Event event) is executed the method doProcessBeforeOutput() is executed as well.
I look over your code and found the following:
1) In method onHeaderClick you sort the table model and store the table model in the bean
2) In method doProcessBeforeOutput() you create a new table model from scratch (in helper method tableViewFormat())and store it in the bean. Thus you overwrite the sorted model.
I suggest that you move the initial creation of the table model in method doInitialization(). Do not forget to store the created table in the bean. In method doProcessBeforeOutput() you retrieve the table model from the bean instead of creating a new one for every request.
Best regards,
Martin

How to enforce always sorting on a column in a TableView?

Hello,
I have a requirement to always sort on a column in a TableView.
So basically, I need a TableColumn's SortType go from Ascending to Descending and back to Ascedning when user clicks on a column header repeatedly.
I guess that means making sure a TableView's SortOrder list is not empty. Am I right?
I tried to listen to SortOrder list changes like below:
tableView.getSortOrder().addListener(new ListChangeListener<TableColumn<String, ?>>() {
 @Override
 public void onChanged(final javafx.collections.ListChangeListener.Change<? extends TableColumn<String, ?>> arg0) {
if (tableView.getSortOrder().size() > 0) {
 // fine. nothing to do
 else {
// add the removed column back
Is this the right approach?
I'm not sure how to use arg0 and add the removed column back.
Can people with experience in this area provide some sample code?
Thanks.

The solution I came up with was to save the last column added to the SortOrder list to a map.
Whenever the SortOrder list becomes empty, I add the last saved column back to the SortOrder list.
That seems work.

Problem in sorting tableview line item

Hi,
I have only one main page with with one tableview.
For example, i have the fields in header say field1, field2, field3, field4, field5.
When i click the header of the field say field2, it sorts the line item which is in table display w.r.t field2.
But i intend to sort the internal table line item , which is responsible to display the line item on page.
Is it possible. If so how?
Cheers
RK

Hi,
You have to use SORT = "SERVER" and in input processing validate the code:
Please see the below example:
In the view the code should something as below:
<htmlb:tableView id="tv2" table="<%=it_vbak%>"
 selectionMode = "none"
 onHeaderClick = "some"
 sort = "SERVER"
 iterator = "<%=controller%>" >
<htmlb:tableViewColumn columnName="VBELN" > </htmlb:tableViewColumn>
<htmlb:tableViewColumn columnName="ERDAT" > </htmlb:tableViewColumn>
<htmlb:tableViewColumn columnName="ERZET" > </htmlb:tableViewColumn>
<htmlb:tableViewColumn columnName="ANGDT"> </htmlb:tableViewColumn>
<htmlb:tableViewColumn columnName="ERNAM"> </htmlb:tableViewColumn>
<htmlb:tableViewColumn columnName="VBTYP" > </htmlb:tableViewColumn>
</htmlb:tableView>
In the event handler the code would be something as below:
data: tv type ref to cl_htmlb_tableview.
tv ?= cl_htmlb_manager=>get_data(
 request = runtime->server->request
 name = 'tableView'
 id = 'tv2' ).
sort it_vbak by (tv->data->column_key).

TableView initial sort

Hi,
I want to have an initial sort of a table and it should be done by the server. I know I could do it by application, but this is just a question if it is possible.
I found for the htmlb:tableViewColumn the attribute preSelectedSortDirection = "DESCENDING". But it seems that it is just showing the sort direction....
My tableView look like this one:
<htmlb:tableView id = "time"
 table = "//model/tab_time"
 emptyTableText = "do data"
 selectionMode = "<%= selectionmode %>"
 fillUpEmptyRows = "TRUE"
 sort = "SERVER"
 visibleRowCount = "3"
 width = "100%" >
 <htmlb:tableViewColumns>
 <htmlb:tableViewColumn columnName = "personid"
 title = "person"
 sort = "TRUE" />
 <htmlb:tableViewColumn columnName = "time"
 title = "time"
 edit = "TRUE" />
 <htmlb:tableViewColumn columnName = "wdate"
 title = "date"
 edit = "TRUE"
 sort = "TRUE"
 preSelectedSortDirection = "DESCENDING" />
 <htmlb:tableViewColumn columnName = "shortcomment"
 title = "comment"
 edit = "TRUE"
 sort = "TRUE" />
 </htmlb:tableViewColumns>
</htmlb:tableView>
Thanks for help,
Stefan Huemer

my guess is that preSelectedSortDirection is only to mark the right icon.
lets take a case.
you sort the itab ascending and pass it to htmlb:tableView without using preSelectedSortDirection in column definition. in this case though the sorting is in ascending order the icons in the table header wont tell whether the current situation is ascending sort to descending sort.
so the way to use it
if you sort the itab passed to htmlb:tableview in ascending order by column a and b initially then set preSelectedSortDirection to 'ASCENDING' to column a and b .
if you sort the itab passed to htmlb:tableview in descending order by column a and b initially then set preSelectedSortDirection to 'DESCENDING' to column a and b .
if you have not sorted the itab passed to htmlb:tableView then dont set anything for preSelectedSortDirection

TableView Sorting issues

Hi,
Just a short question about sorting. In one of our tables, there are entries for a column that have names starting With and without capital letters. Now, is there a way to force the sort to not care whether or not the first word is Capitalized or not?
Thanks and best regards,
Kevin

Hi Kevin,
follow for example more or less the code given in this thread: Functionality to dynamically sort tableview columns and implement a compare method corresponding to your needs (for example using compareToIgnoreCase method of String).
Hope it helps

Functionality to dynamically sort tableview columns

Has anybody successfully tried sorting columns of a tableview component by clicking on its header? I need to sort a column containing dates in mm/dd/yyyy format. Please share your hints or code. BR, Maulin

Hi,
Here is the code, no support included :-):
import java.util.Collections;
import java.util.Comparator;
import java.util.Vector;
import com.sapportals.htmlb.table.DefaultTableViewModel;
public class SortTableModel extends DefaultTableViewModel implements Comparator {
 protected int currCol;
 protected Vector ascendCol; // this vector stores the state (ascending or descending) of each column
 protected Integer one = new Integer(1);
 protected Integer minusOne = new Integer(-1);
 public SortTableModel() {
 super();
 ascendCol = new Vector();
 public SortTableModel(Vector vec) {
 super(vec);
 ascendCol = new Vector();
 public SortTableModel(Vector vec, Vector vec2, int numberOfColumns) {
 super(vec, vec2);
 ascendCol = new Vector();
 setSortOrder(numberOfColumns);
This method is the implementation of the Comparator interface.
It is used for sorting the rows
 public int compare(Object v1, Object v2) {
 // the comparison is between 2 vectors, each representing a row
 // the comparison is done between 2 objects from the different rows that are in the column that is being sorted
 int ascending = ((Integer)ascendCol.get(currCol)).intValue();
 if (v1 == null && v2 == null) {
 return 0;
 } else if (v2 == null) { // Define null less than everything.
 return 1 * ascending;
 } else if (v1 == null) {
 return -1 * ascending;
 Object o1 = ((Vector)v1).get(currCol);
 Object o2 = ((Vector)v2).get(currCol);
 // If both values are null, return 0.
 if (o1 == null && o2 == null) {
 return 0;
 } else if (o2 == null) { // Define null less than everything.
 return 1 * ascending;
 } else if (o1 == null) {
 return -1 * ascending;
 if (o1 instanceof Number && o2 instanceof Number) {
 Number n1 = (Number)o1;
 double d1 = n1.doubleValue();
 Number n2 = (Number)o2;
 double d2 = n2.doubleValue();
 if (d1 == d2) {
 return 0;
 } else if (d1 > d2) {
 return 1 * ascending;
 } else {
 return -1 * ascending;
 } else if (o1 instanceof Boolean && o2 instanceof Boolean) {
 Boolean bool1 = (Boolean)o1;
 boolean b1 = bool1.booleanValue();
 Boolean bool2 = (Boolean)o2;
 boolean b2 = bool2.booleanValue();
 if (b1 == b2) {
 return 0;
 } else if (b1) {
 return 1 * ascending;
 } else {
 return -1 * ascending;
 } else {
 // default case
 if (o1 instanceof Comparable && o2 instanceof Comparable) {
 Comparable c1 = (Comparable)o1;
 Comparable c2 = (Comparable)o2; // superflous cast, no need for it!
 try {
 return c1.compareTo(c2) * ascending;
 } catch (ClassCastException cce) {
 // forget it... we'll deal with them like 2 normal objects below.
 String s1 = o1.toString();
 String s2 = o2.toString();
 return s1.compareTo(s2) * ascending;
This method sorts the rows using Java's Collections class.
After sorting, it changes the state of the column -
if the column was ascending, its new state is descending, and vice versa.
 public void sort() {
 Collections.sort(dataVector, this);
 Integer val = (Integer)ascendCol.get(currCol);
 ascendCol.remove(currCol);
 if (val.equals(one)) // change the state of the column
 ascendCol.add(currCol, minusOne);
 else
 ascendCol.add(currCol, one);
 public void sortByColumn(int column) {
 this.currCol = column;
 sort();
 public void setSortOrder(int numberOfColumns) {
 for (int i = 0; i < numberOfColumns; i++) {
 ascendCol.add(one);
