How to add checkbox control at the Header of DatagridviewCheckBoxColumn?

Question

Can anyone please provide the C# coding to add checkbox control at the Header of DatagridviewCheckBoxColumn.

Answer 1

Convert the Check Box Column to a template field. Then add the Check box to the header template.

Answer 2

I think WarithNath is right. Here is a suggestion code.

<asp:TemplateField>
   <EditItemTemplate>
        <asp:CheckBox ID="CheckBox1" runat="server" />
   </EditItemTemplate>
   <ItemTemplate>
        <asp:CheckBox ID="CheckBox1" runat="server" />
   </ItemTemplate>
   <HeaderTemplate>
       <asp:CheckBox ID="CheckBoxToSelectAll" runat="server" />
   </HeaderTemplate>

</asp:TemplateField>

Hope it works!
