GridView自动增加序号

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

 
//后台---分页了之后进行累加。
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(); 
} 
}
