Hey Enrico,

Thanks for finding the problem. I attached an updated Office2010 Blue style which is newer than the build you're using. Please  use this and report back if you have any more issues.

Hi,

I just had some time to occupy myself with that problem again.

Whenever I open a ChildWindow on a page where a XamGrid is visible, an ApplicationUnhandledException will be thrown.

{System.InvalidOperationException: Cannot resolve TargetName contentPresenter.
   bei MS.Internal.XcpImports.VisualStateManager_GoToState(Control reference, String StateName, Boolean useTransitions, Boolean& refreshInheritanceContext)
   bei System.Windows.VisualStateManager.GoToState(Control control, String stateName, Boolean useTransitions)
   bei System.Windows.Controls.Primitives.Thumb.UpdateVisualState(Boolean useTransitions)
   bei System.Windows.Controls.Primitives.Thumb.OnIsEnabledChanged(IsEnabledChangedEventArgs e)
   bei System.Windows.Controls.Control.OnIsEnabledChanged(Control control, EventArgs args)
   bei MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)}

This behavior is not with the default XamGrid style, only with the style from the theme Office2010Blue.xamGrid.xaml, so it seems to be an issue with the Office2010 style.

I have this behavior an different development machines, so you should be able to reproduce it using the Office2010 style.

BTW: I'm using version: 10.3.20103.2065

Could you please check this for me.

Thanks,

Enrico
