In Radgrid, I use RadComboBox to filter the contents of a column in the code behind as the DataSourceId of RadComboBox needs to be set programmatically based on the user's selection. The filter works Ok and the SelectedIndexChanged fires an event in the code behind. However, when I select the first item, which I included in the markup to clear out the filter, an event does not fire and I cannot clear out the filter.
The item, which I include in the markup, looks like the following:
<Items>
<telerik:RadComboBox Text="" Value="" />
</Items>
Any help will be appreciated.
