Hi Mike,
I want to have checkbox for each dropdown item of Ultra-combobox. Do we have any such feature for combo-box. I need to do this to select multiple items at same time and then submit the form..
How can I implement this.. ?

Hello!
I'm trying to use your code, but i've caught an error:
"An unhandled exception of type 'System.ArgumentException' occurred in Infragistics2.Shared.v10.2.dll
Additional information: Key already exists"

Viktor,
What is the full call stack for the exception and what is the line of code causes the exception?
Alan, thank yout for your reply!
The exception was happening because there is already a "Selected" column in the combo. Most likely it was being added elsewhere or the InitializeLayout event is getting called twice which might happen if you change the DataSource and rebind the WinCombo.
Another way to address this would have been to check a column with the key "Selected" already exists before adding it.
I am happy to hear that you have resolved the issue in your application.
Solved the problem by using ultraComboEditor :)
Thanks!
