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();
}
