GridGroupingControl - Error

[Badri Rajani Kanth]

Hi,
We are using Syncfusion 3.2.1.0.
Can you please tell us why this error occurs?

System.IndexOutOfRangeException: Index was outside the bounds of the array.
at Syncfusion.Windows.Forms.Grid.Grouping.GridTableDescriptor.EnsureRecordRowColumns()
at Syncfusion.Windows.Forms.Grid.Grouping.GridTableControl.SynchronizeGridWithEngine()

Thanks and Rgds

Hi Rajani,

Any calls into the grid must be done on the thread that creates it, and you can use grid.InvokeRequired to check for this. Please check this KB article.

Here is a GroupingGrid sample.

Let me know if this helps. Also can you send us a sample reproducing this behavior?

Sorry for the inconvenience caused.

Best Regards,
Haneef.
