 First make sure that TotalAmount field should be decimal in the datatable. If this is string then change with the below code.

decimal d = 0;
decimal total = dt.AsEnumerable().Where(row => decimal.TryParse(row["TotalAmount"].ToString(), out d)).Sum(row => d > 0 ? d : 0);

Yes you can. For that you have to take template field something like below.

        <asp:Label ID="lblText" Text='<%# Eval("Text") %>' runat="server" />
        <asp:Label ID="lblValue" Text='<%# Eval("Value") %>' runat="server" />
