I am using wpftoolkit datagrid and i want to bind SortMemberPath and Binding different for DataGridTextColumn in datagrid.
I am using below code but its not working
<d:DataGridTextColumn Header="test" Binding="{Binding Path=A}" SortMemberPath="{Binding Path=B}"></d:DataGridTextColumn>

I want to show text value using Binding and sort as per SortMemberPath value.
Any suggestion please
