I'm something of a WPF noob so please take it easy on me ;-) I am trying to create a grouped DataGrid (WPF toolkit version). I have successfully created the data source, the DataGrid itself, the required CollectionViewSource and the Style for the group header (which uses an expander). I want to group by a property called 'Assign_To' and have the relevant value (the value that the grouped items share) show up in the header. However, I cannot work out how to bind to the current group/item in order to return its Assign_To property. The closest I have got (shown below) is binding to the overall CollectionViewSource, which returns a fixed value for Assign_To. What would be the proper way to bind to the current item/group in order to return the correct value for 'Assign_To'? Hope someone can help. Thanks! Andy T.
