Hi Datamex,

There is no functionality to filter items in the RadListBox.  It might be better to use the RadComboBox instead, it has the filter functionality built in.

Hi,
Any plans of adding that functionality?
It would be very useful.
Thanks.

Hi Aykut,

Currently there are no plans to add such a feature for the RadListBox. Load on demand is required for that functionality, however, RadListBox does not support LOD at the moment.

Best wishes,

I wanted this functionality as well.  I made a "starter" project that does this and posted it in the code library.

I put a textbox above a RadListBox and when you type in it, it filters the RadListBox items much like the RadComboBox.
