Hi,

I am using UltraComboEditor in a WinGrid. I create the UltraComboEditor in the grid_InitializeRow method. The data is added as a semicolon-separated string. This works fine.

When I check an item in one comboBox of the row, I want to deselect the same item in all other comboboxes of the same row.

I handle this in the combo_ValueChanged event handler, and I tried to handle it also in the grd_CellChange event handler.

I search the other combo boxes by the following cast:

UltraComboEditor cmbSel = grdBalFad.Rows[0].Cells[ind].EditorComponent as UltraComboEditor;

Now I want to uncheck items by calling cmbSel.SetCheckState (items, System.Windows.Forms.CheckState.Unchecked);

The items parameter is a collection of items to uncheck ValueListItems from the cmbSel.Items collection.

I also tried to by changing the CheckState of the ValueListItem in the grd.Items collection.

Nothing changes in the checkstate of the combobox.

I noticed also that the cmbSel.SelectedItems collection is always empty.

Any idea how to solve this problem.

Thanks in advance and kind regards,
