you need template column, :

<columns>     ...      ...      <asp:templatefield>         <itemtemplate>             <asp:label id="lblseventhcol" runat="server"                  ondatabinding="lblseventhcol_databinding"></asp:label>         </itemtemplate>     </asp:templatefield> </columns> 

and

protected void lblseventhcol_databinding(object sender, eventargs e) {     (sender label).text = getdynamicdata(); }
