GridView自动增加序号(三种实现方式)

<asp:TemplateField HeaderText="序号" InsertVisible="False"> 
<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. 
 代码如下:

<asp:TemplateField HeaderText="序号" InsertVisible="False"> 
<ItemStyle HorizontalAlign="Center" /> 
<HeaderStyle HorizontalAlign="Center"/> 
<ItemTemplate> 
<asp:Label ID="Label2" runat="server" Text='<%# this.GridView1.PageIndex * this.GridView1.PageSize + this.GridView1.Rows.Count + 1%>' /> 
</ItemTemplate> 
</asp:TemplateField> 
 
还有一种方式放在cs代码中,和第二种相似. 
 代码如下:

<asp:BoundField HeaderText="序号" ></asp:BoundField> 
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
if (e.Row.RowIndex != -1) 
{ 
int indexID = this.GridView1.PageIndex * this.myGridView.PageSize + e.Row.RowIndex + 1; 
e.Row.Cells[0].Text = indexID.ToString(); 
} 
}
