Hi

I have specific requirement as below.
I have a GridView generated in my code where 2 columns will have buttons and the remaining columns are auto-generated.
In this GridView, I have to freeze the header row and the two columns which has buttons.

Is it possible?
Because when I search I'm getting the header rows can't be frozen in a GridView where AutoGenerateColumn = "true".

Kindly suggest.

Please find the Grid structure below:

<asp:GridView ID="grdInternalCostRateData" runat="server" CellPadding="3" EnableModelValidation="True"
                           ForeColor="Black" GridLines="Vertical" BackColor="White" BorderColor="#999999"
                           BorderStyle="Solid" BorderWidth="1px" OnRowEditing="grdInternalCostRateData_RowEditing"
                           OnRowCancelingEdit="grdInternalCostRateData_CancelEdit" OnRowDeleting="grdInternalCostRateData_RowDeleting"
                           OnRowUpdating="grdInternalCostRateData_RowUpdate" OnRowUpdated="grdInternalCostRateData_RowUpdated">
                           <AlternatingRowStyle BackColor="#CCCCCC" />
                           <Columns>
                               <asp:CommandField ShowEditButton="True" ButtonType="Button"  />
                               <asp:CommandField ShowDeleteButton="True" ButtonType="Button" />
                           </Columns>
                           <FooterStyle BackColor="#CCCCCC" />
                           <HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" />
                           <PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
                           <SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" />
                       </asp:GridView>
