    Can you post the html? That is actually fairly easy.

    this is the checkbox on the gridview as per your suggestion:
    <asp:TemplateField HeaderText="Select all">
    <ItemTemplate>
    <asp:CheckBox ID="chkselectchild" runat="server" />
    </ItemTemplate>
    <HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="50px" />
    <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="50px" />
    <HeaderTemplate>
    <asp:CheckBox ID="chkselectall" runat="server"
    Text="Select All" />
    </HeaderTemplate>
    </asp:TemplateField>
