DataTable.DefaultView.Sort doesn't seem to be working

Question

I populate a DataTable, then sort the DefaultView of that DataTable. When I set the DataTable as the source for my report, the sort doesn't work. In case it helps, here is the code (GetData returns a valid DataTable):

    Dim dt As DataTable = a.GetData(Parm1, Parm2, Parm3)

    If rbtSortByField1.Checked Then
        dt.DefaultView.Sort = "Field1 ASC"
    ElseIf rbtSortByField2.Checked Then
        dt.DefaultView.Sort = "Field2 ASC"
    ElseIf rbtSortByField3.Checked Then
        dt.DefaultView.Sort = "Field3 ASC"
    End If

    rpt.SetDataSource(dt.DefaultView.Table)
    'This also doesn't work
    'rpt.SetDataSource(dt)

ASSUMING this is a Crystal Report...

See this article. You can't sort on the datasource, you need to have the report do the sorting.
