问题 I am using the windows phone emulator. I wrote a very simple program: draw a marker on the map when the user tap the map once. Then I used map_tap event, and get the tapped location as follows, private void map_Tap(object sender, System.Windows.Input.GestureEventArgs e) { Point p = e.GetPosition(null); GeoCoordinate s = map.ConvertViewportPointToGeoCoordinate(p); Ellipse myCircle = new Ellipse(); myCircle.Fill = new SolidColorBrush(Colors.Blue); myCircle.Height = 20; myCircle.Width = 20;

I actually have all this working pretty good. I have the following Silverlight XAML: <Grid x:Name="LayoutRoot" MaxWidth="500" MinWidth="100" MaxHeight="500" MinHeight="100"> <Grid.DataContext> <app:MainPageViewModel/> </Grid.DataContext> <ScrollViewer> <ItemsControl ItemsSource="{Binding TextItems}"

问题 I can't seem to find a Label control in Silverlight. I get compile errors if I put anywhere in my XAML. 回答1: TextBlock is roughly the same as a Label from WinForms.

EDIT : I just noticed your tag for Silverlight 3. Label should be built into Silverlight 3 so are you sure your not using 2? You might want to
