silverlight

问题 When I test my Silverlight 2 app in Firefox, when Silverlight has focus, I have no problem receiving every key press via the Page.KeyDown event. When I test it in Internet Explorer 7, I can only get keyboard events that the browser doesn't already handle. HOWEVER, I can override those same keyboard events in javascript. For instance, Ctrl + D . I can override this in javascript by doing the following, but I can't do the same thing in Silverlight!! function initKeyHandling(){ document

问题 The problem I have a page with a silverlight object. It attempts to retrieve XML from another (external cross domain) page. But I am struggling with a security exception. I have this code working brilliantly in WPF. When using a website hosting a silverlight application with the same code, the user agent string of the HttpRequest object is null (and seemingly cannot be set). In fact there is no header information at all - this causes a security exception when attempting to make my

How to do that in the Loop? The Items on the ListBoxSource are only Image controls and no other controls. I cannot find any solutions on the net because most of the

问题 I'm just wondering if there is a way to set a vertical threshold of where you want a story board item to appear on the screen (when sliding in and out) so that it doesn't have to slide across everything on the screen when it's popping in and out. I have an list of items that get flipped though according to a timer event but when an item comes onto the screen it passes over all the other buttons and user controls and it doesn't look very pretty. It would be nice if I could just make it appear

问题 I need to set the CredentialsProvider from code behind prior to load the control on page. I have "ApiKey" dependency property in code behind and binding it to Bing Maps silverlight Control but it doesn't work. It gives an error "invalid credentials" at run time.

问题 I haven't been able to find an explanation, or think of a reason why it's not available in non-OOB apps. So why is the toast notification only available in OOB apps? 回答1: Silverlight 4 Out-Of-Browser apps can operate in full trust. This is necessary to open a window separate from the primary window. Toast notifications are separate windows. 来源： https://stackoverflow.com/questions/6684366/why-is-silverlight-toast-notification-only-available-in-oob-app

问题 IIS 6.0 hosting ASP.NET 3.5. From the Visual Studio 2008 aspx code behind (aspx.cs) running on the server I need to determine if Silverlight is installed on the client and if so which version. I know from Java on the client this can be done. That is not what I need. I know I can put in a control that will render if Silverlight is installed. That is not what I need. 回答1: It seems Silverlight does not add any information to the user-agent string that is sent to the server with every request (by
