Clearing a combobox with load on demand

[Silvio Silva Junior]

Hello guys.

I have a combobox with load on demand in a gridtemplatecolumn. For new registries my combo works fine, but, for update I have a problem. In the itemDataBound event (edit mode), I bind the combo with a value and a text (only 1 item), and, when I start the combo's ItemsRequested event, my combo have at the finish, a duplicated item.

I tryed do remove the item in ItemsRequested event,

if (combo.Count == 1)
   {
     combo.Items[0].Remove();
     combo.Text = "";
     combo.ClearSelection();
   }

or, not insert the item that already exist, but I have no sucess.

if (combo.Items.Count > 0)
            {
                if ( itemToInsert != combo.Items[0].Value)
                {
                    combo.Add(new RadComboBoxItem(TextToInsert, valueToInsert));
                }
            }

What is the best practice for it?

Thanks in advance.

Regards.

Hi Silvio Silva Junior,

Having a static item in load on demand combobox is not a supported scenario.
Please find attached a sample project which shows how to use load on demand combo in RadGrid.

Hope this helps.

All the best,
