During our testing phase we discovered an issue that appears to be within the Infragistics libraries. I didn't see anything obvious in the API's that would provide a work around for this. We are using infragistics v13.2. Any suggestions on a solution?
Scenario:
User clicks on the HeaderArea and drags the dialog window
While this is occurring we programmatically close the dialog
Exception Thrown:
UNHANDLED EXCEPTION: System.NullReferenceException: Object reference not set to an instance of an object.at Infragistics.Controls.Interactions.XamDialogWindow.HeaderArea_MouseMove(Object sender, MouseEventArgs e)at System.Windows.Input.MouseEventArgs.InvokeEventHandler(Delegate genericHandler, Object genericTarget)at System.Windows.RoutedEventArgs.InvokeHandler(Delegate handler, Object target)at System.Windows.RoutedEventHandlerInfo.InvokeHandler(Object target, RoutedEventArgs routedEventArgs)at System.Windows.EventRoute.InvokeHandlersImpl(Object source, RoutedEventArgs args, Boolean reRaised)at System.Windows.UIElement.RaiseEventImpl(DependencyObject sender, RoutedEventArgs args)at System.Windows.UIElement.RaiseTrustedEvent(RoutedEventArgs args)at System.Windows.UIElement.RaiseEvent(RoutedEventArgs args, Boolean trusted)at System.Windows.Input.InputManager.ProcessStagingArea()at System.Windows.Input.InputManager.ProcessInput(InputEventArgs input)at System.Windows.Input.MouseDevice.Synchronize()at System.Windows.Input.MouseDevice.OnHitTestInvalidatedAsync(Object sender, EventArgs e)at System.Windows.Input.InputManager.HitTestInvalidatedAsyncCallback(Object arg)at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs)at MS.Internal.Threading.ExceptionFilterHelper.TryCatchWhen(Object source, Delegate method, Object args, Int32 numArgs, Delegate catchHandler);
Hello,
Can you please provide a sample that reproduces this issue for us to test? We'd greatly appreciate it. Let us know if you have any additional questions.
