Frank,

>I'm having a problem with getting the Delete option to work on a XAML window. When I press the Delete button nothing happens. I am figuring it must be something to do with the fact that the screen's datacontext is set like this:

>this.DataContext = this.CourierAirWayBill.DataSet.Tables[this.CourierAirWayBill.TableName].DefaultView;

I recommend setting a breakpoint in the Delete method of the WPF window to see if it's firing. If it is, you can step through the code to get a clearer picture of what's happening.
