Unhandled Exception in designer and during runtime


We are using the dockingManager with multiple contentControls.

If we set the all contentControlsexcept one to "AutoHidden", we are getting an unhandled exception.

bei System.Windows.DependencyObject.SetValueCommon(DependencyProperty dp, Object value, PropertyMetadata metadata, Boolean coerceWithDeferredReference, Boolean coerceWithCurrentValue, OperationType operationType, Boolean isInternal)
   bei System.Windows.DependencyObject.SetValue(DependencyProperty dp, Object value)
   bei Syncfusion.UI.Xaml.NavigationDrawer.SfNavigationDrawer.RefreshSlider()
   bei Syncfusion.UI.Xaml.NavigationDrawer.SfNavigationDrawer.SfNavigationDrawer_SizeChanged(Object sender, SizeChangedEventArgs e)
   bei System.Windows.SizeChangedEventArgs.InvokeEventHandler(Delegate genericHandler, Object genericTarget)
   bei System.Windows.RoutedEventArgs.InvokeHandler(Delegate handler, Object target)
   bei System.Windows.RoutedEventHandlerInfo.InvokeHandler(Object target, RoutedEventArgs routedEventArgs)
   bei System.Windows.EventRoute.InvokeHandlersImpl(Object source, RoutedEventArgs args, Boolean reRaised)
   bei System.Windows.UIElement.RaiseEventImpl(DependencyObject sender, RoutedEventArgs args)
   bei System.Windows.UIElement.RaiseEvent(RoutedEventArgs e)
   bei System.Windows.FrameworkElement.OnRenderSizeChanged(SizeChangedInfo sizeInfo)
   bei System.Windows.ContextLayoutManager.fireSizeChangedEvents()
   bei System.Windows.ContextLayoutManager.UpdateLayout()
   bei System.Windows.UIElement.UpdateLayout()

This also appears sometimes running the application and set contentControls to AutoHidden in the application. It always says something like "width = -8.5 ...".

Kind regards

Hi Marco,

Thanks for contacting Syncfusion support.
We were unable to reproduce the reported scenario on our end. To better understand the root cause and assist with resolving the issue, it would be helpful if you could provide more detailed information about the scenario in which our control was used, including a sample demonstrating the issue with replication steps. Please let us know if you have any other queries.
