The provided information is not enough to determine the cause of the error and it will be difficult to provide a specific solution without more context or code examples.
Can you please send a screenshot of the error and its stack trace along with your aspx and codebehind page to examine the RadGrid declaration and configuration?
Also, here are a few general suggestions to help you troubleshoot the issue:
Examine the object type: Verify that the object you are trying to use as a filter is the correct type expected by the RadGrid control. Double-check the documentation or code examples to ensure you are using the appropriate object type.
Review the code logic: Examine the code where you are attempting to use the object as a filter. Ensure that the logic is correct and the object is being used in the proper context.
Check the spelling and syntax: Ensure that you have correctly spelled the object name and any related properties or methods. Make sure there are no typographical errors or misplaced characters.
Validate the data source: Make sure the data source bound to the RadGrid control is correctly configured and provides the necessary data for filtering.
Tip: For advanced features such as those listed above, RadGrid must be bound using declarative data sources or through the NeedDataSource event. When using declarative data sources or the NeedDataSource event, RadGrid can automatically accommodate the appropriate database operations without the need for you explicitly handle any sorting, paging, grouping, and so on.
Search for similar issues at the Telerik AJAX forum and StackOverflow: Search online forums or developer communities to see if others have encountered a similar error message with the RadGrid control. You might find specific solutions or suggestions tailored to your situation.
