Try couple of things[^]:
1. Put the Gridview data binding in !IsPostback condition.
2. Set Viewstate as false for the gridview

If this does not resolve then, have a look at this similar discussion: http://www.dotnetspider.com/forum/162893-Gridview-problem.aspx[^]

It says: If the Columns collection contains a column that does not support callbacks, such as TemplateField, a NotSupportedException exception is raised.

Knowledgebase is here: GridView.EnableSortingAndPagingCallbacks Property [^]
