repeater里添加序号的两种方法（前台，后台）
前台实现方法：
在<form></form>中添加<Label ID="dd" ></Label>
<body onload="show()">
<Script Language="JScript">
function show()
{
var obj = document.all.tags("LABEL");
for (i=0;i<obj.length;i++)
{
document.all["dd"][i].innerHTML=i+1;
}
}
</script>
后台实现方法：
在.aspx里添加<asp:Label id="Label1" Runat="server"></asp:Label>
在.cs里添加
private void InitializeComponent()
{
this.Repeater1.ItemDataBound += new System.Web.UI.WebControls.RepeaterItemEventHandler(this.Repeater1_ItemDataBound);
this.Load += new System.EventHandler(this.Page_Load);
}
private void Repeater1_ItemDataBound(object source, System.Web.UI.WebControls.RepeaterItemEventArgs e)
{
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
((Label)e.Item.FindControl("Label1")).Text = Convert.ToString(e.Item.ItemIndex + 1);
}
}
