<toolkit:MenuItem Header=”Open” Click=”Button1_Clicked” />
<toolkit:MenuItem Header=”Open read-only” Click=”Button1_ClickedRO” />
<toolkit:MenuItem Header=”Open as copy” Click=”Button1_ClickedAC” />
6. Add Csharp code for click handlers for main button click or any of the three sub-option clicks.
private void Button1_Clicked(object sender, RoutedEventArgs e)
MessageBox.Show(“Opening document normally…”);
private void Button1_ClickedRO(object sender, RoutedEventArgs e)
MessageBox.Show(“Opening document read-only…”);
private void Button1_ClickedAC(object sender, RoutedEventArgs e)
MessageBox.Show(“Opening document as a copy…”);

Summary of SplitButton Usage

Using the SplitButton is similar to using other tools in the Silverlight Toolkit, you simply need to add references to the toolkit, and to the button itself, and then you can code the XAML by referring to the xml namespaces you added.
