Random grid error seemingly to filtering

[Rob]

I have lots of windows within my app that use the radgridview. I'm getting random errors such as the attached. Your help would be appreciated. I'm using the latest version: 2022.2.621.60.

Many thanks

Rob

Hello Rob,

Thank you for the provided stack trace.

From it, I believe the issue is identical to the one from this bug report: GridView: NullReferenceException thrown when the column filtering icon that opens the FilteringControl is clicked. It can be observed if a custom control template from an older version of the suite is used for the FilteringControl element which does not contain the newly-introduced (and required) "PART_" elements.

As can be observed from the feedback item, the bug was fixed with the 2022.2.711 internal build which is available for download from your Telerik account. If you cannot use this build, the fix will be available with our next official release in the middle of September.

On a side note, for the time being, you can also extract and modify the new control template (from the 2022.2.621) version to ensure that all required PART_ elements are present.

I hope you find this information helpful. Do let me know if using the latest internal build or using the new template resolves the issue for you.

Regards,

Many thanks for your reply.

As you identified applying the new control templates from the internal build did solve this issue for me.
