Question : trouble with sorting columns on gridview in ASP.NET 2.0

I am having trouble sorting columns on a gridview in ASP.NET 2.0.
I finally got paging to work, but the sorting does not seem to do anything (not sure how I re-populate the datatable in the code behind).
The events are firing just fine, but I can't seem to make it work (because I am binding the GV with a button click instead of at design time):

ForeColor="#333333" GridLines="None" HorizontalAlign="Left" PageSize="2" Width="600px" AllowPaging="True" AllowSorting="True" >

Text="Name" DataNavigateUrlFormatString="editaffiliates.aspx?iden={0}" >

Answer : trouble with sorting columns on gridview in ASP.NET 2.0

I went ahead and took the wizard approach and decided not to build a gridview from scratch :) .
Once I figured out I could take advantage of the datasource control and load the connection string from the Page_Init (instead of at design-time), there was no point in building a gridView from scratch. Also, the sort feature works fine if you use a datasource.
