I am trying to change the filter element behavior of a ComboBoxColumn. I would like the ComboBoxColumn filter element to behave identical to the filter element for a TextBoxColumn. I need the filtering to be textbased instead of a drop down and I need the DisplayElement to be filtered as opposed to filtering the ValueMember. Is this possible?

Hi TWade,
Thank you for writing.
In general you can implement filtering by DisplayMember through the CustomFiltering event. However, we do not support changing the default combo box editor for a filter cell, and use it in this event. You can only implement this by using a separate editor (common RadTextBox control for example). We are aware of this known limitation: support of custom filtering will be extended to provide this functionality in one of the future releases. For the time being, you have to use a text editor placed outside the grid.
Let me know if you have any additional questions.
Sincerely yours,
