Getting the selected index of a UIX MessageChoise

Hi .
I have a UIX page with MessageChoise.
On the same page I have a submit button with an event named getSelectedIndex.
I let the event invoke an UIX event handler method named
getSelectedIndex(....).
Question: How do I get the Selected index of the MessageChoise in this method.
Please help .Thank's
Omar Dawod.

If it is a bound message choice....
I am now able to get the selected value from the message choice....
<messageChoice model="${bindings.BuildingId1}" name="BuildingList" required="yes">
<contents childData="${bindings.BuildingId1.displayData}">
<option model="${uix.current}"/>
</contents>
</messageChoice>Then in the action....
JUCtrlListBinding b = (JUCtrlListBinding)ctx.getBindingContainer().findCtrlBinding("BuildingId1");
Row r = (Row)b.getValueFromList(Integer.parseInt(ctx.getHttpServletRequest().getParameter("BuildingList")));
String selectedVal = r.getAttribute(1);Hope it helps....

How do i get the selected index in jsp from a select "in the same page!!!"

i dont if it si possible but i want to get the selected index form a select implmenting javascript jsp an html something like this:
html:select property="slcLocation" onchange="updateList(this.form)">
<% for (int i=0; i< user.getNumLocaliza();i++)
out.println("<option selected>" + user.getLocation(i,1));
%>
</html:select> </div></td>
...

i try it in the same page but it fails, the code is:
<html:select property="slcLocation" onchange="document.location.href='cajaApertura.jsp?slcLocation='+this.options[this.selectedIndex].value">
<%
for (int i=0; i< user.getNumLocaliza();i++)
out.println("<option>" + user.getLocation(i,1));
%>
</html:select>
</div></td>
</tr>
<tr>

<html:select property="slcCaja" onchange="document.location.href='cajaApertura.jsp?asdf='+this.options[this.selectedIndex].value">
<%
int caja;
if (request.getParameter("slcLocation")!=null)
//for (int i=0; i< cajaLocation.getNumCajas (request.getParameter("slcLocation"));i++)
for (int i=0; i< 3;i++)
caja = i+1;
out.println("<option> Caja p " + caja + request.getParameter("slcLocation"));
}else
for (int i=0; i< cajaLocation.getNumCajas (user.getLocation(0,1));i++)
caja = i+1;
out.println("<option> Caja " + caja);

is this correct? what is my mistake?

¿How can I to get the selected index from a table in sapui5?

I have a multiselect table for each item I need to open a Dialog and bind then the table.
How Can I to obtain the index position from my table?
var myTable = sap.ui.getCore().byId(this.sId);
var myItem = sap.ui.getCore().byId(myTable.getSelectedItem());
Thanks in advance.

Hi,
You can also use getSelectedContexts of table instance to get the selected indices of sap.m.Table
var aContexts = myTable.getSelectedContexts(true);
for(var i = 0 ; i < aContexts.length ; i++)
var selectedIndex = parseInt(aContexts[i].sPath .split("/")[2]);
Thanks,

Getting the selected index of a table (CL_WD_TABLE) without lead-selection

Hi
When I click in a table-UI (not alv-table) on a f4-help, I can search with se11-searchhelp on a field. After I choose something, I should also fill some other fields in the same row.
In the table I have no lead-selection. So, I am searching for a method that gets me the selected index. The element-class for the table-UI is CL_WD_TABLE.
Once I have the selected index, I could change the fields in the same row inside the WDDOMODIFYVIEW.
With activated node-selection it can be, that the user selects one row, but he starts the f4-help on another row (the lead-selection doesn't change).
I have seen this article, but i hope that for the table-UI it is different than with alv:
[ON_CELL_ACTION triggered only by ENTER ?]

Hi Lorenzo,
I'm trying to do the same thing and came up with this solution. In WDDOMODIFYVIEW, since we cannot know in which table row the user clicked the search help, I simply loop through all the rows of the table. For each row, I delegate to a method in the Component Controller which sets the specified index as the table's lead selection then reads the selected table row from the context. I can then populate fields in the selected row as needed.
METHOD wddomodifyview .
   DATA lo_componentcontroller TYPE REF TO ig_componentcontroller.
   DATA lo_nd_items TYPE REF TO if_wd_context_node.
   DATA lt_items TYPE wd_this->elements_items.
* -- Upon return from the search help, populate table row details
   lo_componentcontroller = wd_this->get_componentcontroller_ctr( ).
   lo_nd_items = wd_context->get_child_node( name = wd_this->wdctx_items ).
   lo_nd_items->get_static_attributes_table( IMPORTING table = lt_items ).
* Since we cannot know in which table row the user requested the search help,
* loop through all table rows, populating table row details as needed.
   DESCRIBE TABLE lt_items LINES sy-tfill.
   DO sy-tfill TIMES.
*   Delegate to the Component Controller
     lo_componentcontroller->get_table_row_detail( sy-index ).
   ENDDO.

How to get the column index of the selected column

Hi All,
I have a dynamically populated advanceddatagrid. Iam trying to edit any column of a particular row. In my as file im able to get the row index using selecteditem property. But I need to get the column Index and the updated value of the column to be passed from the as file to the java method.
So that I can update the DB with the updated value. Can somebody help with a sample code.

...then index 0 becomes index 1 and my program doesn't work properlyThe program works properly, just not as you expect it to.
As you've noticed the table gives you the flexibility to move columns around. So if you move column 0 to column 1, why would you expect to still use 0 as the index? The table manages the reordering of columns for you to make sure the data being displayed in each table column comes from the correct column in the data model.
You can manage this yourself using one of the following methods (I forget which one):
table.convertColumnIndexToModel(int viewColumnIndex)
table.convertColumnIndexToView(int modelColumnIndex)
Or, you can get data from the data model directly:
table.getModel().getValueAt(row, 0);

Is there a way to get the selection order for selectedProperties?

app.project.activeItem.selectedLayers seems to be ordered by the selection order, but app.project.activeItem.selectedProperties (at least in Shape Layers) seems to be ordered by the stacking order. Is there a way to get the selection order for selectedProperties?
Thank you!

Hi,
i had tried to investigate this a while back and it's really hard to figure out.
The array seems to be reorganized using various rules:
     At layer level : preserve the user layer selection order,
     Children of indexed groups : propertyIndex ordering,
     Children of named groups : some internal ordering.
The following is may be more detail than necessary, and given that it is based on observation, not official docs, it is not so reliable, but well, it might still be of interest !!
Say you have 2 selected properties A, and B, and call [COMMON PARENT] their "greatest common ancestor", that is:
        A = [COMMON PARENT].property(a1).... property(aA);
        B = [COMMON PARENT].property(b1).... ...property(bB);
with a1 != b1. Then:
if [COMMON PARENT] = A (ie if A is an ancestor of B), then A comes first.
        For instance: if you select comp.layer(1).mask(1).maskPath, there are 2 selected properties, the mask group and its maskPath: the first is the group and the second the path (the parent comes first).
if [COMMON PARENT] is the containing composition, ie A is a property inside comp.layer(a1), and B a property inside comp.layer(b1), then A and B are ordered according to the layers selection order.
        This can have some strange side effects. For instance:
            deselect everything
            select comp.layer(2) (and nothing else)
            select comp.layer(1).transform.position
            select comp.layer(2).transform.position
            ===> comp.selectedProperties = [comp.layer(2).transform.position, comp.layer(1).transform.position] even though the first entry was effectively selected after the second...
if [COMMON PARENT] is an indexed group, A and B are ordered by propertyIndex
        For instance:
            if you select comp.layer(1).mask(2), then comp.layer(1).mask(1), mask(1) appears before mask(2)
if [COMMON PARENT] is a named group, ... no clue (internal ordering).
        For instance, at propertyDepth 1, it seems that Time Remapping < Effects < Masks < Material Options < Transform, etc, independantly of the selection order, and this is also not the propertyIndex ordering.
        At higher depth, in CS5 the ordering seems to be the propertyIndex ordering, but it is no longer true in CC.
        For instance, selected Position (index 2), Scale (index 6) and Opacity (index 11) in various order on the same layer.
        in CS5 : selectedProperties = [Position, Scale, Opacity];    // propertyIndex ordering, always
        in CC : selectedProperties = [Scale, Position, Opacity];    // always the same ordering, but not the propertyIndex one
So the ordering is a lexicographic ordering (Compare the ancestor of depth 0. If no difference, compare the ancestor of depth 1. If no diff, compare the ancestor at depth 2. And so forth).
But at each step, the comparaison depends on the type of the ancestor, and when the type is named group, the ordering is internal so we can't know.
Practically the most important thing is that selected properties seem to be reorganized by "containing layer" (the layer selection is preserved),
and then in each layer selected properties are "grouped by same parent": you can't have a mask related property, then an effect related property, then another mask related property:
all masks related properties appears together, all effect related properties appear together, etc.
If several effects are selected, effect(1) and all its properties appear first (if selected), then effect(2) and all its properties would appear second etc
and so forth

Get the item index with mouseRollOver with HorizontalList

Hi All
I'm very much interested in the index of the item which triggers an event (in a HorizontalList)
For example, if I move my mouse over the 2nd item in a HorizontalList, I want to get a 1
Here is a code snippet
       public function prepareDisplay(event:ListEvent):void {
          mx.controls.Alert.show("index=" + myList.selectedItem) ;
   ]]>
</mx:Script>
     <mx:HorizontalList id="myList"
          itemRollOver="prepareDisplay(event)"/>
This code always show:
       index=0
because the selected index is not changed with a mouse over. Any suggestions ?
thnx
Luca

              mx.controls.Alert.show("index=" + event.columnIndex.toString())

How to get the selected entry from a Dropdown (using IF_WD_SELECT_OPTIONS)

Hello,
I created a Selection screen by adding attribute M_HANDLER of type IF_WD_SELECT_OPTIONS.
This way I can create a selection screen with normal select-options.
Now I added a parameter for a dropdown list. The Value set is passed correctly. No problem there. The values are filled and diplayed correctly.
* add the SHIP-TO field to the selection
DATA: ltp_text TYPE string.
DATA: lta_ship_to_table type WDY_KEY_VALUE_table,
        lwa_ship_to       like LINE OF lta_ship_to_table.
DATA: context_node_ship_to_table TYPE REF TO if_wd_context_node.
* get all declared attributes
context_node_ship_to_table = wd_context->get_child_node( 'SHIP_TO_TABLE' ).
context_node_ship_to_table->get_static_attributes_table(
    IMPORTING
      table = lta_ship_to_table ).
ltp_text = wd_assist->if_wd_component_assistance~get_text( 'L01' ).
wd_this->m_handler_dlv->add_parameter_field(
                         i_id           = 'KUNWE'
                         i_description = ltp_text
                         i_as_dropdown = 'X'
                         it_value_set   = lta_ship_to_table
                         i_within_block = 'BLK1' ).
The problem is to GET the selected value in the method that is called after clicking on the Search button.
I tried using several methods, for example GET_PARAMETER_FIELD and GET_SELECTION_SCREEN_ITEMS.
* Get the Ship-to
DATA: ltp_kunwe       TYPE REF TO data.
ltp_kunwe = wd_this->m_handler_dlv->get_value_of_parameter_field(
                                        i_id = 'KUNWE' ).
* Assign it to a field symbol
ASSIGN ltp_kunwe->* TO <fs_kunwe>.
Result was INITIAL.
DATA: lrf_get_selection_screen_items TYPE if_wd_select_options=>tt_selection_screen_item.
wd_this->m_handler_dlv->get_selection_screen_items(
              IMPORTING
                 et_selection_screen_items = lrf_get_selection_screen_items ).
Result was INITIAL, although the table was retrieved with all values.
wd_this->m_handler_dlv->get_parameter_field(
                                      EXPORTING
                                        i_id = 'KUNWE'
                                      IMPORTING
                                        e_value = ltp_kunwe ).
Also INITIAL.
It looks like I am missing a step (maybe to set lead selection for this field). What did I miss?
How can I get to the value?

Thanks!
Problem solved:
DATA: lr_value             TYPE REF TO data.
CREATE DATA lr_value TYPE string.                     "<---- I was missing this code
LOOP AT lta_ship_to_table INTO lwa_ship_to.
    value_set-key   = lwa_ship_to-key.
    value_set-value = lwa_ship_to-value.
*    INSERT value_set INTO TABLE lt_value_set.
    append value_set TO lt_value_set.
ENDLOOP.
ltp_text = wd_assist->if_wd_component_assistance~get_text( 'L01' ).
wd_this->m_handler_dlv->add_parameter_field(
                          i_description = ltp_text
                          i_id           = 'KUNWE'
                          i_value        = lr_value   "<---- I was missing this code
                          i_as_dropdown = abap_true
                          it_value_set   = lt_value_set
                          i_within_block = 'BLK1' ).
I looked at that parameter, but thought is was only used to SET the value, not required to get it back as well. Because it IS an import parameter...

How to get the selected items from listbox

Regarding listbox i have two questions
1) I want to get the selected items as per the order in which ihave selected.Presently i'm getting in the ascending order.For example after selcting the 1,2,6 if i select 3 then its giving 1,2,3,6.But i want it in the order 1,2,6,3
2)I want to select items from a single list box to many other listboxes.(ie) my first selection should goto first,second one to the second listbox and like this.How should i write the logic.
please give me a suggestion.

In order to have the selected items line up in accordance to the selection order, please do it one at a time. (That's the limit for that VI)
If you need more than that (i.e. to regconize which item clicked first and which one comes later), you may have to figure it out ya
Wish you good luck. Perhaps, someone else has a already made vi.
Cheers!

How to get the selected values from the shuttle

Hi
Please tell me how to get the selected option values from the shuttle leading list.
Thanks

you can also obtain the option values present in the leading and trailing lists using the
following methods:
public String[] getLeadingListOptionValues(OAPageContext pageContext, OAWebBean
webBean)
public String[] getTrailingListOptionValues(OAPageContext pageContext, OAWebBean
webBean)For example, the following code sample returns an array of values in the trailing list, ordered according to the
order in which they appear in the list:
String[] trailingItems =
shuttle.getTrailingListOptionValues(pageContext, shuttle);Thanks

How can I get the selected rows from two ALV grids at the same time?

I have a program that uses two ALV grids in one dialog screen. I'm using the OO ALV model (SALV* classes).
The user can select any number of rows from each grid. Then, when a toolbar pushbutton is pressed, I'd have to retrieve the selected rows from both grids and start some processing with these rows.
It is no problem to assign event handlers to both grids, and use the CL_SALV_TABLE->GET_SELECTIONS and CL_SALV_SELECTIONS->GET_SELECTED_ROWS methods to find out which rows were marked by the user. Trouble is, this only works when I raise an event in each grid separately, for instance via an own function that I added to the grid's toolbar. So, I can only see the selected rows of the same grid where such an event was raised.
If I try to do this in the PBO of the dialog screen (that contains the two grids), the result of CL_SALV_SELECTIONS->GET_SELECTED_ROWS will be empty, as the program does not recognize the marked entries in the grids. Also, an event for grid1 does not see the selected rows from grid2 either.
As it is right now, I can have an own button in both grid's toolbar, select the rows, click on the extra button in each grid (this will tell me what entries were selected per grid). Then, I'd have to click on a third button (the one in the dialog screen's toolbar), and process the selected rows from both grids.
How can I select the rows, then click on just one button, and process the marked entries from both grids?
Is it somehow possible to raise an event belonging to each grid programmatically, so that then the corresponding CL_SALV_SELECTIONS->GET_SELECTED_ROWS will work?
Thanks.

Hello Tamas ,
If I try to do this in the PBO of the dialog screen (that contains the two grids), the result of CL_SALV_SELECTIONS->GET_SELECTED_ROWS will be empty, as the program does not recognize the marked entries in the grids. Also, an event for grid1 does not see the selected rows from grid2 either.--->
is it possible to have a check box in each grid & get the selected lines in PAI of the screen ?

How to get the selected node value of a tree which is build on java code

Hi Experts,
How can i get the selected node value if I build the tree programatically.
I am using the following code in selectionListener but it is throwing error.
RichTreeTable treeTable = (RichTreeTable)getQaReasontreeTable();
CollectionModel _tableModel =
(CollectionModel)treeTable.getValue();
RowKeySet _selectedRowData = treeTable.getSelectedRowKeys();
Iterator rksIterator = _selectedRowData.iterator();
String selectedQaCode ="";
while (rksIterator.hasNext()) {
List key = (List)rksIterator.next();
JUCtrlHierBinding treeTableBinding =
(JUCtrlHierBinding)((CollectionModel)treeTable.getValue()).getWrappedData();
JUCtrlHierNodeBinding nodeBinding =
treeTableBinding.findNodeByKeyPath(key);
String nodeStuctureDefname =
nodeBinding.getHierTypeBinding().getStructureDefName();
selectedQaCode = selectedQaCode + nodeBinding.getAttribute(0);
where I am using following link to create a tree with java code.
http://one-size-doesnt-fit-all.blogspot.com/2007/05/back-to-programming-programmatic-adf.html
Please help me in resolving this issue.
Regards
Gayaz

Hi,
you should also move
JUCtrlHierBinding treeTableBinding =
(JUCtrlHierBinding)((CollectionModel)treeTable.getValue()).getWrappedData();
out of the while loop as this is not necessary to be repeated for each key in the set

How to get the selected rows & columns in the table?

hi everybody,
In my application the table is kept inside the event structure.I select the cells in the table (using mouse) on running time.How to get the selected number of rows & columns in that table?

Hello,
You can fill selected values of the table by writing to it or the corresponding property using a property node - the table is just a 2D array of strings. I think for your "disable" question you are referring to the shortcut menu (when you right click). If you are using LabVIEW 8.x, you can edit or disable that shortcut menu - just right click on your table at edit time and choose Advanced >> Run-Time Shortcut Menu.
