Asynchronous created control throws InvalidOperationException

I have a problem with a dynamically created GridGroupingControl.
Please take a look at the attached demo solution (VS2005).

There is a Windows form, which invokes a class library asynchronously using BeginInvoke. The control returned by EndInvoke should be visible in the main form and needs to be set. This works with the .NET controls TextBox and DataGridView, but not with the GridGroupingControl (InvalidOperationException, cross thread call on "tableControl1").

Your assistance is highly appreciated.

Thanks in advance,

Hi Michael,

Thanks for your interest in Syncfusion Products.

You can try to make use of the following setting to avoid the Cross-thread exception.

Control.CheckForIllegalCrossThreadCalls = false;
