The provided DependencyObject is not a context for this Freezable

[BENN]

Few of our customers sometimes experience the exception above (I assume it doesn't always happen to them), and we get the crash report through our diagnostics system.

The stack trace is:

  at System.Windows.Freezable.RemoveContextInformation(DependencyObject context, DependencyProperty property)\r\n   at System.Windows.Freezable.RemoveInheritanceContext(DependencyObject context, DependencyProperty property)\r\n   at System.Windows.DependencyObject.RemoveSelfAsInheritanceContext(DependencyObject doValue, DependencyProperty dp)\r\n   at System.Windows.DependencyObject.UpdateEffectiveValue(EntryIndex entryIndex, DependencyProperty dp, PropertyMetadata metadata, EffectiveValueEntry oldEntry, EffectiveValueEntry& newEntry, Boolean coerceWithDeferredReference, Boolean coerceWithCurrentValue, OperationType operationType)\r\n   at System.Windows.DependencyObject.SetValueCommon(DependencyProperty dp, Object value, PropertyMetadata metadata, Boolean coerceWithDeferredReference, Boolean coerceWithCurrentValue, OperationType operationType, Boolean isInternal)\r\n   at System.Windows.DependencyObject.SetValue(DependencyProperty dp, Object value)\r\n   at Telerik.Windows.Controls.RadRibbonWindow.SetThemeTemplate(RadRibbonWindow ribWin)\r\n   at Telerik.Windows.Controls.RadRibbonWindow.OnApplyTemplate()\r\n   at System.Windows.FrameworkElement.ApplyTemplate()\r\n   at System.Windows.FrameworkElement.MeasureCore(Size availableSize)\r\n   at System.Windows.UIElement.Measure(Size availableSize)\r\n   at System.Windows.Interop.HwndSource.Process_WM_SIZE(UIElement rootUIElement, IntPtr hwnd, WindowMessage msg, IntPtr wParam, IntPtr lParam)\r\n   at System.Windows.Interop.HwndSource.LayoutFilterMessage(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled)\r\n   at MS.Win32.HwndWrapper.WndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled)\r\n   at MS.Win32.HwndSubclass.DispatcherCallbackOperation(Object o)\r\n   at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs)\r\n   at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)

 

The problem looks like coming from:

RadRibbonWindow.SetThemeTemplate

Are you aware of issues that can cause it?

 

Thanks.

Hello Benn,

We are not aware what is causing the reported issue. However, I've done a little research on the error and it seems that it usually relates with brushes or images. May I ask you to share some runnable code showing the RadRibbonView setup in XAML and code-behind, so I can check it on my side?

It won't be hard to share all the source code (It is huge, and making a runnable minimized code that will also reproduce the problem is not an easy task, and since this problem is kind of rare and never happened to me in debug then I cannot even guarantee that the given code would ever reproduce it).

I'm also investigating it, and I'll keep you posted if I find anything interesting.

Hello Benn,

Looking forward to hear more about this, if you find anything.

Hi,

We are also noticing the same error. Any update or solution for this issue?

There is still no information on the exact reason behind this issue. What I would recommend you is to share a runnable project that shows the issue in this forum. This way I can try it out and my side and see what happens.
