Hello,
I updated the wpf dlls today to 15.1 from 14.1, but I'm getting an error when I'm opening the windows.
Message: "Object reference not set to an instance of an object."
Source: "InfragisticsWPF4.Controls.Editors.XamComboEditor.v15.1"
StackTrace:
em Infragistics.Controls.Editors.ComboEditorBase`2.XamWebComboEditor_Loaded(Object sender, RoutedEventArgs e) em System.Windows.EventRoute.InvokeHandlersImpl(Object source, RoutedEventArgs args, Boolean reRaised) em System.Windows.UIElement.RaiseEventImpl(DependencyObject sender, RoutedEventArgs args) em System.Windows.BroadcastEventHelper.BroadcastEvent(DependencyObject root, RoutedEvent routedEvent) em System.Windows.BroadcastEventHelper.BroadcastLoadedEvent(Object root) em MS.Internal.LoadedOrUnloadedOperation.DoWork() em System.Windows.Media.MediaContext.FireLoadedPendingCallbacks() em System.Windows.Media.MediaContext.FireInvokeOnRenderCallbacks() em System.Windows.Media.MediaContext.RenderMessageHandlerCore(Object resizedCompositionTarget) em System.Windows.Media.MediaContext.RenderMessageHandler(Object resizedCompositionTarget) em System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs) em System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)
How can I fix the error?
Thanks
I was just about to post the exact same error as I'm having this issue also.
For me I noticed the problem only seems to appear when the combo is in a tab control and not in the first tab
Strange.. Hope there will be a fix for this soon as I'm close to a deadline!
