DynamicLayer + VisibleLayers property

BrianBorg — Thu, 15 Jul 2010 05:23:21 GMT

I am setting the VisibleLayers property in xaml

VisibleLayers="2,7,12"

and I am getting this error:

Error 1 Unable to cast object of type 'Microsoft.Expression.DesignModel.DocumentModel.DocumentPrimitiveNode' to type 'Microsoft.Expression.DesignModel.DocumentModel.DocumentCompositeNode'.

If you get this error in Blend only, it looks like the same issue than

Brian,

Even though you see the error can you still test Run the app? I had the same thing and my app still ran. In the end I moved the VisibleLayers property setting from XAML into C#.

Thanks,

I had to remove it from xaml and put it in c#.

I am not using blend but VS2010

Unfortunately this is a bug in VS2010 (it used to be there in Blend 4 as well, but got fixed after we reported it - unfortunately didn't make it for VS2010). You code will still compile and run though.
