View an object or resource in XAML
When you have an object selected in Microsoft Expression Blend, you can use the View XAML command to switch to XAML view where the line of the XAML that relates to the object that you selected will be highlighted.
For more information about XAML and WPF, see the XAML Overview on MSDN or visit the Windows Developer Center . For the syntax of individual controls, see the links listed in Controls, properties, and events reference.
