I can't find any documentation or examples on how to freeze a row in the Datagrid. I can only find that it is mentioned in the Release documentation for the DataGrid control that you can do it.
How do I freeze a row in a Datagrid. Is it possible to do in WPF or must it be code behind?
Is it possible to Freeze a row that is a GroupHeader?
I.e. as I scroll down the datagrid the group header is froze at the top of the datagrid untill the next Group scrolls onto the page
