GDBG Dropdown list values.

[kstoj]

I''m trying to dynamically change the value of the ComboBox list on one cell in the GDBG.
I''m using following code to do that:
private void AssignmentGrid_CurrentCellShowingDropDown(object sender, GridCurrentCellShowingDropDownEventArgs e)
{
GridCurrentCell currentCell = this.AssignmentGrid.CurrentCell;
GridComboBoxCellRenderer cr = currentCell.Renderer as GridComboBoxCellRenderer;

GridBoundColumn gridBoundColumn = this.AssignmentGrid.GridBoundColumns["FieldWorkerID"];
int colIndex = this.AssignmentGrid.GridBoundColumns.IndexOf(gridBoundColumn) + 1;

if(cr != null && currentCell.ColIndex == colIndex)
{
cr.ListBoxPart.DataSource = UserIdList;
}
else
{
gridBoundColumn = AssignmentGrid.GridBoundColumns["LoadGroup"];
colIndex = AssignmentGrid.GridBoundColumns.IndexOf(gridBoundColumn) + 1;
if(cr != null && currentCell.ColIndex == colIndex)
{
cr.ListBoxPart.DataSource = loadGroups;
AssignmentGrid.GridBoundColumns["LoadGroup"].StyleInfo.DataSource = loadGroups;
}
}
}

The FieldWorkerID Combo Box is:
GridDropDownStyle.AutoComplete style
and LoadGroup ComboBox is:
GridDropDownStyle.Editable style.

Changing the data source on the FieldWorkerID works but it does not on the "LoadGroup".
I checked and re-checked in the Debugger that the data assigned to the "LoadGroup" cell is correct and it is. The renderer data source shows correct list ( in the debugger ) yet when the drop down list is displayed the new values does not show.
What is happening here?

Hi Kstoj, Changing the ComboBox choice list dynamically in a cell works fine. Please refer to the attached sample and let us know if you are trying something different. Regards, Calvin.
