Answer 1

I would suggest you use the gridview RowDataBound event.

At first setup the GV with the appropriate controls then populate the GV with your data and assign the controls with values from your object.

Start with http://www.dotnetgallery.com/kb/resource17-RowDatabound-event-tips-and-tricks-in-Gridview-control.aspx.aspx
