In my Silverlight UI, I have a button that when clicked pops up a control with some filtering parameters. I would like this control to hide itself when you click outside of it. In other words, it should function in a manner similar to a combo box, but it's not a combo box (you don't select an item in it). Here's how I'm trying to capture a click outside of the control to dismiss it: public partial class MyPanel : UserControl { public MyPanel() { InitializeComponent(); } private void FilterButton_Click(object sender, RoutedEventArgs e) { // Toggle the open state of the filter popup FilterPopup

I am working with the Silverlight RIA Services and I want to create custom authentication. This appears to be the only thing that has virtually no documentation (I've read through the entire RIAServicesOverview.docx). Do you know of a way for me to create a customer authentication service? I don't want to use the default ASP.NET membership model. I don't know what interface or abstract class I need to implement - although I did find System.Web.Ria.ApplicationServices.IAuthentication.

As soon as I play a certain MediaElement I can't play another MediaElement on the same page. I don't find

How can I get a screen resolution of Device from settings (Windows Phone) ? public void GetScreenResolution() { string ScreenWidth = Application.Current.Host.Content.ActualWidth.ToString(); string ScreenHeight = Application.Current.Host.Content.ActualHeight.ToString(); MessageBox.Show(ScreenWidth + "*" + ScreenHeight); } This may be a better way to know what screen resolution is your app running on. if(App.Current.Host.Content.ScaleFactor == 100) { // WVGA } else if (App.Current.Host.Content.ScaleFactor == 160) { // WXGA } else if (App.Current.Host.Content.ScaleFactor == 150) { // 720p }
