Select ALL rows in ALV by an ACTION

Hi All -
Is possible to have a button with an Action "select all" and when the user trigger that action all the records in the ALV are selected?
i.e ALV has 10 records (lines or rows) and user click on a button with text "SELECT ALL" and once they click that button all the rows/lines are selected.
Thanks!

Hi ,
yes it can be done....
here is the procedure to do it.....
first we need to make the context node "selection" property equals to "0..n" you can find this property at your component controller level.....where you set your "cardinality" as well...
than create a button in your view layout where the alv is being displayed and write the following code for button action:
DATA lo_nd_alv_table TYPE REF TO if_wd_context_node.
navigate from <CONTEXT> to <alv_table> via lead selection
   lo_nd_alv_table = wd_context->get_child_node( name = wd_this->wdctx_alv_table ).
DATA counter TYPE i.
counter =   lo_nd_alv_table->get_element_count( ).
DO counter TIMES.
      lo_nd_alv_table->set_selected(
    EXPORTING
    index = sy-index ).
ENDDO.
I just tested this...and it worked for me....
Thanks...
AS...
Just forgot to mention....if you want to de-select them all...you can use the method:
lo_nd_alv_table->CLEAR_SELECTION(
the above code can be put in in the btn action method.....say you have two btns one to select all rows and one to de-select all....
this code can go under de-select all btn action method.....

Selecting all rows in ALV on a button click

Hi Experts
Hi,
I have a dynamic ALV table. I also have a button 'Select All Rows'. On clicking the button I want all the rows in the ALV table selected which is done by using set_selected method at the context node.
All the rows in the alv is selected after clicking select_all except for the first row.
Need your inpts to solve the same.
Regards
Karthick

Use the folowing code
*... get model
data:
    lr_model type ref to cl_salv_wd_config_table.
lr_model ?= me->r_model.
*... get columns
data:
    ls_column type salv_wd_s_column_ref,
    lt_column type salv_wd_t_column_ref.
lt_column = lr_model->if_salv_wd_column_settings~get_columns( ).
data:
    l_selected type abap_bool.
loop at lt_column into ls_column.
    l_selected = abap_false.
    read table value transporting no fields with key column = ls_column-id.
    if sy-subrc eq 0.
      l_selected = abap_true.
    endif.
    try.
        me->if_salv_bs_model_column~set_selected(
          column = ls_column-id
          value = l_selected ).
      catch cx_salv_bs_sc_object_not_found.             "#EC NO_HANDLER

Select All rows in WebDybpro Tables

Hi All ,
I am working on NWCE 7.1 . i have table in my UI. and want to give slect all rows functionality in table. in NWCE is there
any way to give select all rows in table with out using , button and writing action to iterate node bound to table.
also i want to know about RowCreator ui element for table.(when we right click on table we get insert -> rowcreator). How this works
Thanks in advance
Regards
Kavita

Hi Kavita,
The row creator Ui element is not visible in table itself you can see it only in outline window.
and in its on create event you have to write the code which i have provided above. it will not be visible in table at design time but at run time when you will click on the last rows lead selection it will call the associated event and one row will be added to the table.

Select all rows in af:table

Hi,
I need to select all rows in af:table, not only on current page.
I have following code on custom select all action:
getTable2().getSelectionState().addAll()and on button that needs to perform some action on selected rows I have this code
        Set selectedRowSet = getTable2().getSelectionState().getKeySet();
        if (!selectedRowSet.isEmpty()) {
            Iterator it = selectedRowSet.iterator();
            while(it.hasNext()) {
                Key key = (Key)it.next();
       }selectedRowSet.iterator() method throws java.lang.ClassCastException: oracle.jbo.Key.
When I select rows with af:tableSelectMany, which is inside selection facet and selects only rows on current page, this works fine.
Any ideas?
Thanks

Hi,
you can only access those data that is queried and part of the CollectionModel to the time you select all
   RichTable _table = employeesBackingBean.getEmployeeTable1();
   RowKeySet rks = new RowKeySetImpl();
CollectionModel model = (CollectionModel)_table.getValue();
int rowCount = model.getRowCount();
      for (int i = 0; i < rowCount; i++) {
           model.setRowIndex(i);
           //note that in the simple POJO case, the row key is the same
           //as the index. However, it would be wrong to just rely on this
           //because other models or custom table models my return a more
           //comples key. Therefore we iterate over the available rows to
           //obtain the keys.
           Object key = model.getRowKey();
           //add the row keys to the RowKeySet to mark selected
           rks.add(key);
   _table.setSelectedRowKeys(rks);
   AdfFacesContext.getCurrentInstance().addPartialTarget(_table);Frank

Removing the select all icon from ALV

Hi
I'm using CL_GUI_ALV_GRID to display an ALV grid. Can I get rid of the standard "select all" icon from the top left corner of the grid? I don't want the user to be able to use this icon, but can't see a way of removing it.
Regards
Phil

Hi Phil
That means you do not want the user to select multiple rows. Because letting the user to select multiple rows always gives him the opportunity to select all rows even without using the button you mentioned.
Then you must set the "sel_mode" of the layout structure to "B" to make user select one row only.

Thanking you.

Hi Sahoo,
If you are using the class CL_GUI_ALV_GRID. In methods SET_TABLE_FOR_FIRST_DISPLAY.
in layout structure you will find field SEL_MODE
pass :
LS_LAYOUT-SEL_MODE = 'A'.
In PAI.
CALL METHOD GRID->GET_SELECTED_ROWS
    IMPORTING
      ET_INDEX_ROWS = T_ROWS
      ET_ROW_NO     = T_ROWID.
Hope these will solve your problem.

Not able to select a row in ALV?

Hi Experts,
I am enhancing a standard e-recruiting WD ABAP component.
It produces a search result as ALV.
I am not able to select any row in ALV by clicking it like we normally do in ALV.
I wrote below code to allow selection:
lo_value->if_wd_salv_table_settings~set_selection_mode( cl_wd_table=>e_selection_mode-single).
Even after this I am not able to select any row by clicking it.
Need help to solve this.
Regards,
Sumit Oberoi

Hi,
To have the inputfields for the ALV.
Get the column references of the ALV table and for each column rference create a inputfield object
type CL_SALV_WD_UIE_INPUT_FIELD.
lo_value is model object.
CALL METHOD lo_value->if_salv_wd_column_settings~get_columns
    RECEIVING
      value = wd_this->lit_columns.
LOOP AT wd_this->lit_columns INTO wd_this->lis_columns.
      lv_id = wd_this->lis_columns-id.
      wd_this->gref_column = wd_this->lis_columns-r_column.
case lv_id.
when ' colname'.
            CREATE OBJECT lr_input
              EXPORTING
                value_fieldname = lv_id.
            CALL METHOD wd_this->gref_column->set_cell_editor
              EXPORTING
                value = lr_input.
when ' colname'.
            CREATE OBJECT lr_input
              EXPORTING
                value_fieldname = lv_id.
            CALL METHOD wd_this->gref_column->set_cell_editor
              EXPORTING
                value = lr_input.
endcase.
endloop.
Or you can take a attribute READ_ONLY for the node to which ALV table is bound.
Set the readonly property to abap_false (for input field) by looping through the table.
Get the column references and get the textview reference for each column and use the set_read_only
method by passing the attribute name.
This way the textview will now become the inputfield when the read_only property is set to abap_false.

Lekha.

HOW TO SELECT ALL ROWS IN A MULTI SELECT TABLE!!!!!

Hello
I have a table with tableSelectMany component. how can I set the page to initially select all rows when first opened?????

efffffttttttt? are you saying you will do an electronic funds funds funds funds funds transfer transfer transfer transfer transfer transfer to anyone who answers?
What version of JDeveloper are you using - that is quite important in order to be able to give you an answer.
What also might be useful is "please" and "thank you" instead of SHOUTING IN ALL CAPS THAT YOUR QUESTION IS IMPORTANT. Realizing that you asked this question over a weekend when most people dont sit and read the forum...
You have a habit of saying all your questions are URGENT!!!!!! which is generally considered, um...., impolite.

How to set selected all rows in h:dataTable

hello, I want to selected all rows in a dataTable.
I use JS to got it:
the selectBooleanCheckbox in the header of row:
<t:selectBooleanCheckbox id="aa" value="#{list.checkbox}" />the JS code :
<script type="text/javascript" language="JavaScript1.2">
    function selectAll(obj, first, size) {
        for (var i = 0; i < size; i++) {
            var current = eval(first - 1 + i);
            var objs = document.getElementById("form:listbody:listtable:" + current + ":aa");
            obj.checked ? objs.checked = true : objs.checked = false;
</script>and the "selectall" code:
<h:selectBooleanCheckbox id="selectAll"
                              onclick="javascript:selectAll(this,#{firstRow},#{displayedRowsCount})"/>It run good in IE,but not it does not work in firefox.
Are there some method to do?
Or is there a method to select all rows just use JSF?
Needs you help!

Yes, the paging for <h:dataTable> works pretty good, it manages the task through four methods created in the java code -- DataTable1_firstPageAction(), DataTable1_previousPageAction(), DataTable1_nextPageAction(), DataTable1_lastPageAction() -- without adding any javascript in the jsp page.
Maybe I could test if a java script similar to the <ui:table>'s one fit also the dataTable...
thanks

How to select all rows in table automatically after refreshing?

Hi,All
After refreshing the table,I want to select all rows,like MultipleButton's function.
How can I do?
Thanks
Smile.

Hi,-Grif-
* Set the selected state for the given row groups
* displayed in the table. This functionality requires
* the 'selectId' of the tableColumn to be set.
* @param rowGroupId HTML element id of the tableRowGroup component
* @param selected Flag indicating whether components should be selected
function selectGroupRows(rowGroupId, selected) {
var table = document.getElementById("form1:table1");
table.selectGroupRows(rowGroupId, selected);
}I don't know that the parameter selected is a boolean,or the checkbox(radio button) id?

Select mutiple rows in ALV report output

Hi All,
I want to select the Multiple records i in ALV report output with out holding the CNTL(Control Key).
Is there any options in Layout?
Please let me know
regards,
Ajay
Edited by: Ajay reddy on May 30, 2010 3:27 PM

Hi Ajay,
To select several rows without Control button, if the rows are adjacent:
- select the first and the last of the desired rows with Shift button pressed
or
- select a row, keep the mouse button pressed, and pass over the desired rows
I don't know an option without Control if the rows are not adjacent.

Selection of rows in ALV grid (class CL_GRID_CATSXT)

Hi all,
The CATS transaction CATS_APPR_LITE is using the class CL_GRID_CATSXT, method GET_SELECTED_ROWS, to retrieve selected rows in the ALV report.
The user/manager selects these rows to approve the work hours registered by his subordinates. He can only select and approve those rows that have been fully expanded, meaning he cannot select and approve total lines. (If he tries to do so, nothing happens).
I have created a layout that shows only total lines per employee. Using this layout the manager should be able to select the total line for a particular employee and press the "Approve" button. In this way, I need to get a hold of the rows contained in the total line, meaning I need the row numbers of the actual rows which have been added up in the total line.
Does anyone know how to do this...? As mentioned earlier, the CATS_APPR_LITE transaction is using class CL_GRID_CATSXT, method GET_SELECTED_ROWS.
All helpful answers will be rewarded!
Best regards,
MV

I guess method GET_SELECTED_ROWS returns the total lines when they are selected ?
if so, you just have to do a LOOP on your internal table having same key fields as selected total line

When user select 1 row in alv some other rows must automaticaly get selecte

When user selects say any row in alv with vbeln = 1234 all rows which have vbeln = 1234 also must get selected automaticaly.Is there some event to handle row selection in alv by clicking the push button beside each row to left of ALV?

Hi
U can implement an your push button in order to select the remaining rows: in user-command u need to implement a code where u get the selected line and the select the other.
Or simply u can select the other lines as soon as the user do something after selecting a row.
How to do it depends on whick kind of alv you're using: if the internal table fir output has a flag field for the marker, "To select a line" means to check that field.
