                     ItemsSource="{Binding Source={StaticResource RecordValues}}" />


this is the error while debugging the above code:"The invocation of the constructor on type 'WpfApplication1.MainWindow' that matches the specified binding constraints threw an exception.' Line number '8' and line position '9'."

since the beginning of the project I am using xmlns:dg="" . so I can't remove this namespace and opt for DataGrid instead of dg:DataGrid. I know that the problem relies on the usage of the abobe namespace. anybody can help to resolve the issues at the same time retaining dg:

thanks in advance
