Hi,
I am using Rad Grid View of telerik version 8.2.0.0.
Sometimes I get an exception if I call 'best fit' on last column via context menu. It is not reproducible every time and here is complete log
System.NullReferenceException:
Telerik.WinControls.UI.GridHeaderCellElement.menuItemBestFit_Click(Object sender, EventArgs e) bei Telerik.WinControls.RadItem.OnClick(EventArgs e) bei Telerik.WinControls.UI.RadButtonItem.OnClick(EventArgs e) bei Telerik.WinControls.UI.RadMenuItemBase.OnClick(EventArgs e) bei Telerik.WinControls.UI.RadMenuItem.OnClick(EventArgs e) bei Telerik.WinControls.RadItem.DoClick(EventArgs e) bei Telerik.WinControls.RadItem.RaiseBubbleEvent(RadElement sender, RoutedEventArgs args) bei Telerik.WinControls.RadElement.RaiseRoutedEvent(RadElement sender, RoutedEventArgs args) bei Telerik.WinControls.RadItem.RaiseBubbleEvent(RadElement sender, RoutedEventArgs args) bei Telerik.WinControls.RadElement.RaiseRoutedEvent(RadElement sender, RoutedEventArgs args) bei Telerik.WinControls.RadElement.DoMouseUp(MouseEventArgs e) bei Telerik.WinControls.ComponentInputBehavior.OnMouseUp(MouseEventArgs e) bei Telerik.WinControls.RadControl.OnMouseUp(MouseEventArgs e) bei System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks) bei System.Windows.Forms.Control.WndProc(Message& m) bei System.Windows.Forms.ScrollableControl.WndProc(Message& m) bei Telerik.WinControls.RadControl.WndProc(Message& m) bei Telerik.WinControls.UI.RadPopupControl.WndProc(Message& m) bei System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) bei System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) bei System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) # ShowThreadExceptionDialog ---> [L-0] >>> Void HandleThreadException(System.Object, System.Threading.ThreadExceptionEventArgs) >>> Void OnThreadException(System.Exception) >>> Void WndProcException(System.Exception) >>> Void OnThreadException(System.Exception) >>> IntPtr Callback(IntPtr, Int32, IntPtr, IntPtr) >>> IntPtr DispatchMessageW(MSG ByRef) >>> Boolean System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(Int32, Int32, Int32) >>> Void RunMessageLoopInner(Int32, System.Windows.Forms.ApplicationContext) >>> Void RunMessageLoop(Int32, System.Windows.Forms.ApplicationContext) >>> Void Run(System.Windows.Forms.Form)
Can I handle this issue at my end? Please let me know.

Thank you for reporting this issue. I was not able to reproduce it using several tests. Could you please send us the code for the menuItemBestFit_Click method. Any additional details will help us when investigating this issue too. Thank you in advance.
