Hi, When i close a docked control on my docking manager and try disposing my control in the dock visibility changing event thrown by the docking manager, i get the fllowing error after all the disposing has been taken care of in my code. aditionally i make sure i set dockingmanager.setenabledocking for the control to false. the error is this : (System.NullReferenceException) - Object reference not set to an instance of an object.
the stack trace is this: Syncfusion.Windows.Forms.Tools.DockHostController.CloseController() at Syncfusion.Windows.Forms.Tools.DockHostController.HandleMouseUpImp(MouseButtons button, Point pt) at Syncfusion.Windows.Forms.Tools.DockHost.OnMouseUp(MouseEventArgs e) at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ContainerControl.WndProc(Message& m) at Syncfusion.Windows.Forms.Tools.DockHost.WndProc(Message& msg) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) at System.Windows.Forms.ComponentManager.System.Windows.Forms.UnsafeNativeMethods+IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run()
could u please throw some light on why u think this could be happening. is there a standard way of disabling a control on dockingManager.
