Silverlite: Why datagrid column sorting might not be working

Column sorting in my recent Silverlight 2.0 Datagrid app wasn't a priority, but I wanted to be able to click on a column header and sort, darn it. I added a CanUserSortColumns="true" property to the DataGrid and CanUserSort="true" to each DataGridTemplateColumn. Still nothing.

<data:DataGridTemplateColumn Header="Employee" Width="200" CanUserSort="True"
   SortMemberPath="EmployeeName">
    <data:DataGridTemplateColumn.CellTemplate>

Thank you !

After you indicate this I took a look in MSDN and I found the explanation:

"In columns that are derived from DataGridBoundColumn, such as DataGridTextColumn and DataGridCheckBoxColumn, the SortMemberPath is set to the property that the column is bound to through the Binding property by default. In columns that are derived from DataGridColumn, such as DataGridTemplateColumn, the SortMemberPath property must be set to enable automatic sorting of the column. "
