Hi,
I am trying to filter the RadGrid [Grd_Url] using a RadComboBox [Cmb_Lst_Sel] which is inside "CommandItemTemplate". The RadComboBox has CheckBoxes enable and user can select multiple checkboxes. The RadGrid needs to be selected based on the multiple selection [DataValueField="lst_id"]. How can I do that?

ASPX:

Hello Ali,

The functionality that you are requesting is not available out-of-the-box with templates, but you could take a look at the following Code Library with a sample project, demonstrating how to accomplish the same behavior:
I could also suggest that you take a look at our built-in checklist filtering functionality:
