ASP.NET Gridview is kinda complicate to handle sometimes. First time, I didn't know how to display row count in Gridview. Whatever I tried is displaying vistual ID of database. After that, I found how to display row count in Gridview.

view plain print about
1<asp:TemplateField>
2<ItemTemplate>
3<%# Container.DataItemIndex + 1 %>
4</ItemTemplate>
5</asp:TemplateField>
