Binding data grid view to webmthod

Hi

I am binding data grid view to a web method as below but no data appears in the grid.

    Dim ws As myurl.MyWebService = New myurl.MyWebService

    Dim x = ws.MyWebMethod()

    Me.DataGridView2.DataSource = x

There is data coming in I have checked. I have not added any columns before hand to the grid though. What am I missing?

Regards
