I'm getting this error when using the R. Click Grid Filter Menu and a non date format is entered. Is there a way to validate these controls?
"Line: 6
Error: Sys.WebForms.PageRequestManagerServerErrorException: String was not recognized as a valid DateTime"
"Line: 6

Hi Rory,
Try setting the EnableLinqExpressions of the grid to false and check whether it resolves the error.

Hi Pavlina,
Thanks for the advise but unfortunately that doesn't fix the bug. The error isn't related to LINQ it is coming from the the Filter that is trying to convert the filter string into a DateTime field without providing any sort of validation. This is a bug in Telerik's grid filter control because it allows a GridBoundColumn to be bound with a DateTime type that can apply DateTime filters.

Hi Rory,
At this point, if the problem persists, it would be best if you open a formal support ticket and send us a sample runnable version of your project, so we can debug it locally and find out what causes the error in your scenario.
Thank you.
