GridView增加自动序号列

有三种方式

第一种方式,直接在Aspx页面GridView模板列中.这种的缺点是到第二页分页时又重新开始了.

<asp:TemplateFieldHeaderText="序号" InsertVisible="False">

             <ItemStyle HorizontalAlign="Center" />

             <HeaderStyle HorizontalAlign="Center" Width="5%" />

            <ItemTemplate>

             <%#Container.DataItemIndex+1%>

           </ItemTemplate>

           </asp:TemplateField>

第二种方式分页时进行了计算,这样会累计向下加.

 <asp:TemplateField HeaderText="序号"InsertVisible="False">

             <ItemStyle HorizontalAlign="Center" />

             <HeaderStyle HorizontalAlign="Center" Width="5%" />

            <ItemTemplate>

                <asp:Label ID="Label2" runat="server" Text='<%#this.MyListGridView.PageIndex * this.MyListGridView.PageSize +this.MyListGridView.Rows.Count + 1%>'/>

           </ItemTemplate>

           </asp:TemplateField>

还有一种方式放在cs代码中,和第二种相似.

<asp:BoundFieldHeaderText="序号" >

             <ItemStyle HorizontalAlign="Center" />

             <HeaderStyle HorizontalAlign="Center" Width="5%" />

         </asp:BoundField>

       protected void myGridView_RowDataBound(object sender, GridViewRowEventArgs e)

       {

           if (e.Row.RowIndex != -1)

           {

               int indexID = this.myGridView.PageIndex * this.myGridView.PageSize +e.Row.RowIndex + 1;

                e.Row.Cells[0].Text = indexID.ToString();

            }

        }
