I have followed the example on the site for implementing the RadFilter with a grid.  The control displays, but I get the following error:

 Line: 6
Error: Sys.WebForms.PageRequestManagerServerErrorException: Parameter cannot be null or empty.
Parameter name: fieldName 

This occurs whenever I click the add expression button.

Any help would be appreciated.

Thanks...Brian

Hello Brian,

Could you please provide the url of the demo you have referenced? In case you have modified the code in a local sample based on the demo, please consider opening a formal support ticket and send it to me for an inspection. Once I have a sample code to debug, I would be able to provide more to the point resolution.

All the best,
Martin
