Using Popup to create a Dialog class

You should set TabNavigation=Cycle for your user control so the user doesn't tab outside it on the modal cases.

What if you need to design your dialogs in xaml rather than coding everything up in C# in the GetContent() method?

This may be important if you have lots of complex dialogs that designers create in Blend.

schmiddy - In that case, you can make the dialog subclass return a new UserControl subclass for its content--and design the UserControl subclass as normal.

Crashes on RTW

This doesn't work on 2.0 RTW if the content is non-trivial, e.g. try adding a ListBox inside the dialog and clicking on it a few times -- you get "System Exception: Catastrophic failure".

I've found that doing LayoutRoot.Children.Add(_popup) sorts it, not quite sure of the implications of that though.

maxchristian, yes, anything that calls TransformToVisual under the hood will crash unless you do what you suggest.

The implications are that the popup will be affected by the RenderTransforms that apply to the LayoutRoot, but if you are a little clever you can also get around that if need be.

Ah, so that's why my dialog became enormous when I made the SL control fill the browser window using a RenderTransform...

Can you be more specific? I'm not sure if I'm a little clever but I'm certainly a little lazy. ;)

maxchristian,

You may need to change where you put the RenderTransforms, and/or add an additional element. If you had this:

and the RenderTransforms were on the UserControl or the Grid, and you added the Popup to the Grid, then you may need to do something like this:

Add the newRoot Grid, put the RenderTransforms on the LayoutRoot, and add the Popup to the newRoot.

I am unable to put a ComboBox on a UserControl that is used for a popup window. When I popup the control and touch the ComboBox it hangs. It can be empty or not. Using SL2. Please advise. Thank you.

This is likely due to an SL2 bug. ComboBoxes in a Popup, when the Popup is not in the visual tree (i.e. in the page's XAML) don't work. This has been fixed for SL3.

Ok, thanks. A work around then is to wrap your ComboBox in another UserControl in some way; it just can't sit directly on the popup control. I tried that and it seems to be working.

Thanks for the help.

Thanks!

I find it useful even there is ChildWindow in Silverlight 3 now. ChildWindow is difficult to tune when it provides FullScreen button.

Also it should call UpdateSize() method in Show() method too because user can change the browser size while popup is closed.
