I want to know how you can modify properties of columns of a WPF toolkit datagrid once the ItemsSource has been set (it is set in XAML)? For example I want to make a specific column have the property IsReadOnly equal to true.
So basically there are two things I want to know:
-How can I get access to a specific column once the ItemsSource has been set?
-How can I change the properties of a specific column once the ItemsSource has been set?
