Hi Alex,

Thank you for your interest in Syncfusion products.

The exception is thrown when an operation is performed on the disposed grid. Please check the IsDisposed method of the grid and accordingly handle the situation. For example, to clear the GridBoundColumns, you can follow the below code.


if(!this.gridDataBoudGrid.IsDisposed)
this.gridDataBoundGrid1.GridBoundColumns.Clear();


Is it possible for your to upload a minimal sample that reproduces this issue?. That will help us to analyze this issue further.

Please let me know if you have any further questions.

Best Regards,
Srirajan
