GridGroupingControl - Error while resizing

[Badri Rajani Kanth]

Dear Syncfusion,

We are using V 3.2.1.0 GridGroupingControl.

Our application will resize some screens from size height=0, width=0. We have a GGC with Dock = Fill in one such screen. And when screen is of size (0, 0), we are getting the below error.


System.ArgumentException: Invalid parameter used.

at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m)
at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

To fix this, we are setting Dock = None when GGC size is (0, 0) and else Fill. This is fixing the error but we see flickering effect.

So, we are wondering, if there is any fix so that we can keep GGC.Dock = Fill always, even when GGC size becomes (0,0).

Can you please help?

You can try turning off AllowOptimizeLoadTime property,

this.gridGroupingControl1.AllowOptimizeLoadTime = false;

in your form''s constructor to see if that avoids the problem.

Another thing you can try is to set the size to (1,1) instead of (0,0) to see if that gives you what you need without triggerring this problem.
