Currently, I have two DataTables inside of a DataSet. The first DataTable contains a listing of names and IDs (along with a few other things) that populates the majority of a DataGrid in a WPF application. The second DataTable, contains a listing of usernames and the IDs (that correspond to the IDs in the first DataTable) they correspond to.
My question is, how do you apply the first DataTable to the DataGrid, then populate the comboboxes for the corresponding ID?
