i wanted to display the Payment receipt status as pending for radiobuttonlist1 and radiobuttonlist2's selected text after clicking on Add new linkbutton.

i have used the following in rowdatabound event but its not working :

protected void gvDetails_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        DataRowView drv = e.Row.DataItem as DataRowView;
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if ((e.Row.RowState & DataControlRowState.Edit) > 0)
            {
                RadioButtonList rdott = (RadioButtonList)gvDetails.FooterRow.FindControl("ftrrdottstatus");
                RadioButtonList rdoconfirm = (RadioButtonList)gvDetails.FooterRow.FindControl("ftrrdoConfirmation");
                if (rdott.SelectedItem.Text == "Received" || rdott.SelectedItem.Text == "Not Received" || rdoconfirm.SelectedItem.Text == "Confirmed" || rdoconfirm.SelectedItem.Text == "Not Confirmed")
                {
                    ((Label)gvDetails.FindControl("Label7")).Text = "Payment Receipt Pending";
                }


                ((TextBox)gvDetails.FooterRow.FindControl("txtfpercentage")).Attributes.Add("readonly", "readonly");
                ((TextBox)gvDetails.FooterRow.FindControl("txtftrdifference")).Attributes.Add("readonly", "readonly");
                //((TextBox)gvDetails.Row.FindControl("txtdifference")).Attributes.Add("readonly", "readonly");

                RadioButtonList rbtnl = (RadioButtonList)e.Row.FindControl("rdottstatus");
                rbtnl.SelectedValue = drv[4].ToString();
             

                RadioButtonList rbtnl1 = (RadioButtonList)e.Row.FindControl("rdoConfirmation");
                rbtnl1.SelectedValue = drv[5].ToString();
                
            }
        }
    }

source:

<asp:TemplateField HeaderText="Payment Receipt Status" SortExpression="Payment Receipt Status">
                                                         <ItemTemplate>
                                                           <asp:Label ID="Label7" runat="server" Text='<%# Bind("Paymentstatus") %>'></asp:Label>
                                                       </ItemTemplate>
                                                    </asp:TemplateField>
