Hello,

Here' s my code  about a datagrid with checkboxes.

I need to implement a function to call every time I check a box. How is this possible?

Thanks!

Hi,

you could try it with the EditorBehaviors like this:

    function EditorBehaviors(grid DataGrid in, cell Widget in, rowData any in, rowIndex int in, column DataGridColumn in, value any in) returns(Widget)
        case(column.name)
            when("KOX")
                KOX_CHECK DojoCheckBox{text = "", selected = false, disabled = false, onClick ::= KOX_CHECK_OnClick_do_what_you_want};

                if(rowData.KOX as string == "X")
                    KOX_CHECK.selected = true;
                end
                cell.children =[KOX_CHECK];

        end
    end

I want the event function  to run only if I check every checkBox . 

I have added showCheckBoxes = true in datagrid and the checkboxes have already been created so I don't want to use  case column.name.

Is there any flag in widget's egl file that determines the time I click checkBox like checked=true  or something else?

You could consider using the Datagrid's checkboxListener, which is fired every time a checkbox is (un)selected. Every time you (un)select a checkbox you will be able to retrieve a list of all selected rows (datagrid.checked()). So you will have no direct indication of what row is (un)selected. You would have to keep a list of selected rows outside of the datagrid to be able to determine what new checkbox was selected.

I 'm trying this function and I call it in datagrid as selectionListeners =[myListener] but I  see which checkbox is selected only when I select the row. I want to see it when I check each box instead. Could you help me find it?  And another issue is if there is a way to return a value from mylistener function to use it in another function of the program. Thanks

function myListener(grid DataGrid in)

 sysLib.writeStdOut( "in listener"); 

 

columnRetrieve Rec[]; 

columnRetrieve = grid.getChecked() as Rec[]; 

numberOfRows int = columnRetrieve.getSize();

 sysLib.writeStdOut( "number of rows: " + numberOfRows); 

 if(numberOfRows > 0) 

   for(i int from 1 to numberOfRows)

    sysLib.writeStdOut(columnRetrieve[i].name + " is selected."); 

    end

 end

 end

You shouldn't use the Datagrid's selectionListener. Use the checkboxListener instead.
I expanded your sample code and now functions as you described.
By the way: In my opinion Marcel's solution is more elegant and doesn't require the extra code as I have put in function checkboxListener.

Why do you use the name of column "field1" ? 

How can I retrieve only the number of row which is selected?

Is it possible to change  function checkboxListener (grid DataGrid in) somehow to return the line of the box which is checked?
