gridview增加自动序号列

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:TemplateField HeaderText="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:BoundField HeaderText="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();

             }

         }
