silverlight

问题 I've got a ribbon bar in my silverlight app and on one of the icons I would like for there to be a badge icon showing the number of items in the view that the icon activates. Picture the Mail icon in OS X showing the number of unread messages or the notifications counter on an IOS app icon.

问题 Is there anyway to extract the underlying xaml from a control. IE. I have a textbox named fooBox. Can I get xaml back from the textbox at runtime that represents the textbox? 回答1: This shows you the full lifecycle (from control to XAML back to control).

Please note that any events, animations, etc /// on the source item may not carry over to the cloned

问题 We're investigating using RIA Services (July 09 Preview) to expose parts of an existing EF model. We've added a Domain Service class to our web application and specified the EF model to use and selected a few of the entities we wish to make available via the domain service (some have editing enabled, most do not). We build and everything is great, but if we want to add an additional entity to the domain service how do we do that. Is it a case of delete your current class and re-add and this

The security principles behind the design of the platform prevent applications from accessing user data without them explicitly providing it. 来源： https://stackoverflow

问题 I am having trouble upgrading my current project to use RIA Services. I added all the necessary web.config changes but still no luck. I everything compiles fine but when I hit the page using the datacontext I get an error. I debugged with fiddler and I'm getting a 404 on one of the request.

问题 I want to split an image into several smaller images using silverlight for windows phone 7.5. First of all, i want to know if this is even possible (i had some unpleasant surprises with windows phone APIs lately), and if it is, just give me some example as i have been able to find exactly none.
