There is no requirement to use the control as the root element. It’s simply a content control — wrap whatever you want it to appear over in it. If you have some other control that requires the root to be a grid, put it inside of the grid with other content within it.

Using this control as the root element destroys the ability to open your UserControl / Page in Blend. Also, I have huge problems using 3rd party controls which expect the root element to be a grid in order to function correctly. Is there some way to have this overlay without being the root element?

Hi, I am trying to follow Ria services examples, but I am unable to build the solution.
Error The type or namespace name ‘Activity’ could not be found (are you missing a using directive or an assembly reference?).

I have tried in VS2008 and VS2010, same thing. (Deleting the reference and adding it back in, did not work either.)
However, in a separate SL project, I am able to have a valid reference to a build dll.
Any suggestion? You can email me at

One way to do it is to bind into the page for its status (i.e. make a property on the pages to bind the Activity control to)

If you do that, you can use IsActive=”{Binding Content.ActivityProperty, ElementName=MyFrame}” on your activity control, and it will stay bound to whatever page is currently being displayed.

Gotta love binding!

So, I’ve looked this, and you’re quite right. I’m about to blog an update that makes this value default to false, which should help resolve this issue for now. I wonder how many people actually like that AutoBind functionality, or whether it should be removed?
