Simple DataGrid Sorting Demo

This demo shows how to create a DataGrid with bound columns that allows the user to sort two of the six columns. For this demo clicking on the name will not sort the row, but just indicate what row was clicked. Note that here AutoGenerateColumns is set to True (the default). This will automatically make each column a candidate for sorting.
