Hi @akhter hussain ,
According to the code and the image you provided, I found that there are two Total columns (S.total and Total) in the GridView.
<asp:TemplateField HeaderText="S.Total"> <asp:Label ID="lbltotalDisc" runat="server" Text=""></asp:Label> <asp:TemplateField HeaderText="Total"> <asp:Label ID="lbltotal" runat="server" Text='<%# Eval("lbltotal") %>'></asp:Label>
I recommend that you could delete one of these two columns in the GridView. This will not cause confusion and will solve your current problem.
