hi,
you can use TemplateField in that particular cell to define every collection of controls in that cell. Here is a sample:
<asp:templatefield runat="server" xmlns:asp="#unknown">
<itemtemplate>
<asp:image runat="server" imageurl="image1.gif" />
<a href="Default.aspx">Click here</a>
</itemtemplate>
</asp:templatefield>
I hope it helps,
Cheers
