Here is a sample approach :
Add this tag to your ItemTemplate section :

ASP.NET

<asp:imagebutton id="ibDelete" runat="server" commandname="Delete" imageurl="images/del.gif" xmlns:asp="#unknown" />

and remember that your gridview DataSource should support Delete operation. Here is a sample datasource :

ASP.NET

<asp:sqldatasource id="sdsCountry" runat="server" xmlns:asp="#unknown">
        ConnectionString="<%$ ConnectionStrings:GConnectionString %>" 
        DeleteCommand="DELETE FROM [Country] WHERE [ID] = @original_ID"> 
       <deleteparameters>
            <asp:parameter name="original_ID" type="Int32" />
        </deleteparameters>
</asp:sqldatasource>

Its clear that the Visual Studio will help you by its wizard to create a DataSource which supports all CRUD(Create, Read, Update, Delete) operations.
