Element is already the child of another element error

[Scott]

I have a very simple project where I put a reference to the summer theme's version of ScheduleView.xaml into my App.xaml as a MergredDictonary and if I start the project in debug mode then close the browser I will get an error in Visual Studio's Error List window: Error 1 Element is already the child of another element. App.xaml 7 17 ScheduleViewDesign

Is there any way to fix this? I'm using Q1 2011 SP1.

Hi Scott,

You could try to set the full path instead of filename (e.g. /YourAssembly;component/FolderName/ScheduleView.xaml).
You have to remove /FolderName is ScheduleView.xaml is in project root.

Let us know if this helps.

Unfortunatelly that is what I'm already doing. See attached image. This should be easily reproducable in a simple application as I have done. Thanks for any help.

Hi Scott,

We managed to reproduce the problem, it appears that this is a problem with the design time of the control. If you close the design window of the .Xaml file where the ScheduleView is placed the error will disappear. This error should not have an impact on the application. However we will need some more time to investigate what exactly is causing this bad behavior and fix it.

Please, excuse us for the inconvenience. We have added points to your account for the report. Don't hesitate to contact us if you have other questions.
