C# WPF datagrid: ItemsSource

Question

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?

Answer 1

Answer to both questions is:

• By looping through your datagrid
• Access column by it's index
