UpdateColumnWidths exception

Hello, I''m getting the exception (pasted below) when I remove my GridGroupingControl from the Controls collection (this.Controls.Remove()) of my UserControl. The only way I can avoid this error is to set AllowCalculateMaxColumnWidth to false before removing the GroupingGrid from the controls collection. It may have something to do with the fact that I''m setting the grid DataSource to null before removing it from the controls as it seems to be trying to resize the columns when there is nothing in the DataSource. Any ideas how to get around this? thanks, Heath ************** Exception Text ************** System.IndexOutOfRangeException: Index was outside the bounds of the array. at Syncfusion.Windows.Forms.Grid.Grouping.GridTableModel.UpdateColumnWidths(Boolean force) at Syncfusion.Windows.Forms.Grid.Grouping.GridTableModel.UpdateColumnWidths() at Syncfusion.Windows.Forms.Grid.Grouping.GridTableControl.UpdateScrollBars() at Syncfusion.Windows.Forms.Grid.GridControlBase.OnSizeChanged(EventArgs e) at Syncfusion.Windows.Forms.Grid.Grouping.GridTableControl.OnSizeChanged(EventArgs e) at System.Windows.Forms.Control.UpdateBounds(Int32 x, Int32 y, Int32 width, Int32 height, Int32 clientWidth, Int32 clientHeight) at System.Windows.Forms.Control.UpdateBounds() at System.Windows.Forms.Control.WmWindowPosChanged(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at Syncfusion.Windows.Forms.ScrollControl.WndProc(Message& msg) at Syncfusion.Windows.Forms.Grid.GridControlBase.WndProc(Message& msg) at Syncfusion.Windows.Forms.Grid.Grouping.GridTableControl.WndProc(Message& msg) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

I am not sure this will serve your needs or not. But this code did not throw any exceptions for me. this.gridGroupingControl1.DataSource = null; this.gridGroupingControl1.Visible = false; this.Controls.Remove(gridGroupingControl1); gridGroupingControl1.Dispose(); gridGroupingControl1 = null;
