not sure what your aspx page looks like and what setting you have in you datagrid, but I would first test the datagrid without defining any boundcolumns or customtemplate columns and make sure the autogeneratecolumns is set to true. Just something basic like to see if your data will bind to the grid:

<asp:datagrid id="dataGrid1" runat="server" />

Also make sure you are not returning any null values and include ISNULL(field,”) in you query.

Finally in .net framework 4 you should be using gridview instead of datagrid…not sure if that is a typo.
