Hi,Yatin

       to added controls to the footer of the datagrid we use <footer Template> </footer template> command in <template columns> </template colums>. For example we a button control in a footer of datagrid like this:

<datagrid><columns><template columns><footer template><asp:button id= btn1 label = button runat = server></asp:button></footer template></template columns></columns></datagrid>

in the same way we add controls to header also. by using <header template></header template>
