I think you are missing the MappingName in the TableStyle. You need to indicate the TableStyle the "table" that is bound to.
Try setting this property just after creating the TableStyle.

' VB.NET sample code
Grid.TableStyles.Clear()
Dim TableStyle As New System.Windows.Forms.DataGridTableStyle()
TableStyle.MappingName = TableName

>The client calls a web service setup to a VFP8 dll that returns an XML file with the schema included. That portion works like expected. The XML file is then read and bound to a datagrid. The data displays but for the life of me I can't get the columns to display the data I want, the data being displayed is correct, just not the correct headings and column order.
