gridview新增序号

前台----

页面：

< asp:BoundField   HeaderText ="序号" 　 />

或者：

< asp:TemplateField HeaderText ="序号" >
< ItemTemplate >
</ ItemTemplate >
</ asp:TemplateField >

后台----

cs代码：

protected void GridView1_RowDataBond(object sender, GridViewRowEventArgs e)
{
         if (e.Row.RowIndex >= 0)
         {
         　e.Row.Cells[0].Text = Convert.ToString(e.Row.RowIndex + 1);
         }          
   }

或者

页面实现：

< asp:TemplateField HeaderText = " 序号 " >
< ItemTemplate >
　　　 <% # Container.DataItemIndex + 1 %>
　 </ ItemTemplate >
</ asp:TemplateField >

分页情况下：

< asp:TemplateField HeaderText = " 序号 " >
< ItemTemplate >
<% # this .GridView1.PageIndex   * this .GridView1.PageSize

　　　　　　　　　 + GridView1.Rows.Count + 1 %>
</ ItemTemplate >
</ asp:TemplateField >

序号列RowDataBound事件

-----每页生成1~10的序号

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //1~10
        if (e.Row.RowIndex >= 0)
        {
            e.Row.Cells[0].Text = Convert.ToString(e.Row.RowIndex + 1);
        }      

    }

----生成逐渐增长的序号

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {

        if (e.Row.RowIndex != -1)
        {
            int indexID = this.GridView1.PageIndex * this.GridView1.PageSize + e.Row.RowIndex + 1;
            e.Row.Cells[0].Text = indexID.ToString();
        }        

    }
