GridView Nesnesinde Sütundaki Verileri Toplama
Merhaba arkadaşlar bu makalemizde GridView nesnesinde Quantity sütunundaki değerleri toplamını alt kısma yazdıracağız. Gridview nesnesinin AutoGenerateColumns özelliğini false yapın. GridView nesnesinin Columns kısmına,
<FooterTemplate>
<div style="text-align: right;">
<asp:Label ID="lblTotal" runat="server" />
</div>
</FooterTemplate>
ekleyeceğiz. Buradaki label e sütunun toplamı yazılacak. Gridview_RowDataBound kısmına kodumuzu yazıyoruz.
