Silverlight 4 Equivalent to WPF “x:static”

Question

I\'m working on a project that is based on an old project someone started and didn\'t finish. I was trying to use as much of their code as I could, so in doing so I ran int

Answer 1

Unfortunately, you can't directly use the DynamicResource and Static keywords in a Silverlight's subset of XAML, but you can mimic their behavior. Here is the article on the topic:

• {x:Type} and {x:Static} in Silverlight

In general, there is no easy way to migrate a project from WPF to Silverlight. They have very much in common, but strictly speaking are a different technologies.

Another way to achieve binding to static properties - to bind in code. Below is an example.

Main application class:

public partial class App : Application
{
    public static MyViewModel MyViewModel { get; private set; }

    // ...
}

Main window markup:

<TextBlock Loaded="MyTextBlockLoaded" />

Main window back-code:

public partial class MainPage : PhoneApplicationPage
{
    // ...

    private void MyTextBlockLoaded(object sender, RoutedEventArgs e)
    {
        TextBlock textBlock = ((TextBlock)sender);
        if (textBlock.Tag == null)
        {
            textBlock.Tag = true;
            Binding bind = new Binding("MyInfo");
            bind.Source = App.MyViewModel;
            bind.Mode = BindingMode.OneWay;
            textBlock.SetBinding(TextBlock.TextProperty, bind);
        }
    }
}

Maybe the TextBlock.Tag approach of checking, was Binding already set or not, isn't the most elegant one, but it works.
