My advice would be if you can't get it working with WPF then you'll not get very far with SL.
Also, WPF Unleashed warns about using ActualHeight and ActualWidth as they are updated every time the layout process runs which is asynchronous. Don't know if this has anything to do with what goes on in SL but thought you might like to know. From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Stephen Price Sent: Thursday, 15 May 2008 12:39 PM To: listserver@ozsilverlight.com Subject: [OzSilverlight] ActualWidth Hi guys, I've come across this issue before with WPF, and have now hit something similar in Silverlight. I've got a page with a Canvas element on it called "pageContents" and I'm loading XAML fragments into the contents of the Canvas. That works no problems, but what I'm having issues with is the pageContents.ActualWidth (and ActualHeight) are not updating. The Canvas starts off with no content and Width and Height are not set, so default to Auto. Adding the content automatically sizes the Canvas but the ActualHeight and ActualWidth are still showing as 0 (zero). I've got a snippet of code that tells me if the mouse click was inside the bounds of the Canvas and I need to know the dimensions of the canvas. Calling pageContents.Measure(availablesize) doesn't seem to help. Any other tricks I can use? protected void Page_MouseLeftButtonDown(object sender, MouseEventArgs e) { var contentRect = new Rect((double)pageContents.GetValue(Canvas.LeftProperty), (double)pageContents.GetValue(Canvas.TopProperty), pageContents.ActualWidth, pageContents.ActualHeight); var position = e.GetPosition(null); if (contentRect.Contains(position)) { _lastMousePosition = position; } } thanks, Stephen ------------------------------------------------------------------- OzSilverlight.com - to unsubscribe from this list, send a message back to the list with 'unsubscribe' as the subject.
