* I have a Grid on a page, and i converted a column(Category) to a template then i placed a RadComboBox in the filter section of the template.

* now when i run the page i can see the Category column populating the content and i can select from the drop down menu (filter).

-- looking at the examples and demos included on Telerik Documentation did not help me (as new converter from different programming language to asp.net). Telerik extensions is a great product and such a simple task (like filter in grid using a drop down menu) should be set with few clicks rather than going back and forth modifying this code and that code. and having this drop down column within the Grid should make it easy without the need for all this code..

* in simple way how can i move from here to make the selection work as filter (as for now i can select but doing nothing).

Thanks

Hello Grand,

From the stack trace posted bellow I can see that the issue arise when RadComboBox tries to select item that does not currently exists. This might be caused if you are using load on demand of RadComboBox and after filtering items are still not loaded.

You can check the following demo that demonstrates FilterTemplate of GridBoundColumn and utilizes RadComboBox as filter control.
