Hey,

You could do this work in the RowCreated event of the GridView.

http://msdn.microsoft.com/en-us/libr...owcreated.aspx

Check to see if the RowType is the Header, and if it is, add the necessary controls, and hook up the event handles.

Either that, or edit the HeaderTemplate for the column that you are interested in.

hay,
you can use the HeaderTemplate

Code:

---

<asp:GridView ID="GridView2" runat="server">
        <Columns>
            <asp:TemplateField>
                <HeaderTemplate>
                    <asp:CheckBox ID="CheckBox1" runat="server" Text="Header " />
                </HeaderTemplate>
                <ItemTemplate>
                    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>
