These are something that I've found while developing an application using Silverlight 1.1 Alpha.
1 Create <MediaElement> dynamically by setting the second parameter of the method XamlReader.Load(…) to “true”. Remove it from the root canvas. The browser freezes.
2 Create <MediaElement> dynamically by setting the second parameter of the method XamlReader.Load(…) to “true”. Play some video or audio. Press F5 to refresh the page. Video or audio still plays.
3 You have <Image> element. Get an URL of some image from Flickr. Set the source with that URL. The application stops with an error “Code 3002, Type ImageError, AG_E_NOT_FOUND”. Seems like <Image> does not support HTTP Redirection.
4 (doing drag-and-drop) Hold the mouse button down, capture mouse, move the mouse cursor out of the browser and back into the browser while holding down the button. Try to release the mouse, but it won’t work even though you stop holding the mouse button.
5 When programmatically changing the width and height of Silverlight control, BrowserHost.ActualWidth and BrowserHost.ActualHeight in System.Windows.Interop namespace sometimes does not get updated.
6 When trying to change the value of a HTML element from managed code, the attribute name is case-sensitive for Firefox, not case-sensitive for Internet Explorer.
7 If the height of Silverlight control is greater than 2500px, images start becoming corrupted.
8 The height of Silverlight control is greater than that of the browser window. You’re a half way scrolled down. If you try to give focus on Silverlight control to get keyboard event, focus works, key event works, but it will take you all the way back to
the top of the screen. The proper behavior should not change the previous scroll position.
9 When using dual screen and getting into full-screen mode, Silverlight always shows up on the first screen.
10 Changing z-index programmatically sometimes does not update the screen correctly.
11 When using <VideoBrush>, there’s no way to set its source with the video that is dynamically created.
12 Do not provide all kinds of mouse cursor shapes.
13 I’m guessing that there is some sort of message queue for UI thread in Silverlight as well. I think there should be a way to programmatically process this queue, so that the screen still gets updated while waiting for something to be done.
This is a great list. Thank you for taking the time to debug and report these issues. Some of these were indeed known to me. The others I've logged as bugs in our bug database. I'd also recommend the "report
a Silverlight bug" forum for better visiblity (to folks on the product team and the community) for such issues.
