Based on the sample from http://msdn.microsoft.com/en-us/library/ms771725.aspx which is for WPF. I wanted same sample for silverlight as my requirements are same. but i get "AG_E_PARSER_BAD_PROPERTY_VALUE" pointing to in my XAML (FYI: xmlns:dat="clr-namespace:System.Windows.Data;assembly=System.Windows.Data").
Please help me in achieving the same.
