Problem in Grid Grouping Control in BottomSidebar workspace

If we put Grid Grouping Control to BottomSidebar workspace of the main form and bind to it for example a DataTable
and then begin to edit it - everithing is work good

then we close it and open it again and try to edit it - then an Dispose method of the main form executed and

on the line of code (1)

[STAThread]
public static void Main()
{
new MainClass().Run();//(1)
}

rise an odd exception - Object NullReference Exception!!!

But if we put this user Control with this grid to the MDI workspace - this situation is work good!!!

What I need to correct and what is my trouble??

Best Regards Alexander!!!

Hi Alexander,

Sorry for the inconvenience caused.

Are you refering to BottomSidebar as GridNavigation Control or BottomSidebar is some kind of custom control? Can you be more explanatory about this? you can also send us a sample with this BottomSidebar workspace , so that we will work on it here for you.

Best Regards,
