Thanks for the response.
I'd thought about that previously and it seemed redundant to assigning the DataSource to the datagrid.

So I tried it anyway with the DataSource assignment. Added the TableStyle.MappingName, but I get the same result. I also added assigning a name to ds.Tables[0].Namespace, but same result. I removed the DataSource assignment and get no data in the grid.

DataGridTableStyle ts1 = new DataGridTableStyle();
// New line added
ts1.MappingName = "v_ICPartXML";
