一、在ItemDataBound事件里面动态改变Repeater控件里面的html元素
如：
<asp:Repeater ID="Repeater1" runat="server"
onitemdatabound="Repeater1_ItemDataBound">
<ItemTemplate>
<table>
<tr id="row" runat="server">
<td>
<%#DataBinder.Eval(Container.DataItem,"title")%>
</td>
</tr>
<tr id="row2" runat="server">
</table>
</ItemTemplate>
</asp:Repeater>
后台程序
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
int i = e.Item.ItemIndex;
if (i % 2 == 0)
HtmlTableRow row = (HtmlTableRow)e.Item.FindControl("row");
if (row != null)
row.BgColor = System.Drawing.Color.Black.ToString();
}
HtmlTableRow row2 = (HtmlTableRow)e.Item.FindControl("row2");
if (row2 != null)
//在这里就可以对row2这个html的元素进行各种各样的赋值了
二、在Repeater控件里面嵌套Repeater控件
<asp:Repeater runat="server" ID="rp1" OnItemDataBound="rp1_ItemDataBound">
<tr>
<td >
<div >
<asp:Repeater runat="server" ID="rp1">
<%#DataBinder.Eval(Container.DataItem,"title2")%>
</div>
CS代码
private void Bind()
{ ……
this.rptypelist.DataSource = dt;
this.rptypelist.DataBind();
protected void rp1_ItemDataBound(object sender, RepeaterItemEventArgs e)
//判断里层repeater处于外层repeater的哪个位置（ AlternatingItemTemplate，FooterTemplate，HeaderTemplate，，ItemTemplate，SeparatorTemplate）
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
Repeater rep = e.Item.FindControl("rp2") as Repeater;//找到里层的repeater对象
DataRowView rowv = (DataRowView)e.Item.DataItem;//找到外层Repeater关联的数据项
int title= Convert.ToInt32(rowv["title"]);
……
rep.DataSource = dt2;
rep.DataBind();
三、添加序号的4种方法
1、<itemtemplate>
<tr><td>
<%# Container.ItemIndex + 1%>
</td></tr>
</itemtemplate>
2、<itemtemplate>
<%# this.rpResult.Items.Count + 1%>
</itemtemplate>
3、在<form></form>中添加<Label ID="dd" ></Label>
<body nload="show()">
<Script. Language="JScript">
function show()
var bj = document.all.tags("LABEL");
for (i=0;i<obj.length;i++)
document.all["dd"][i].innerHTML=i+1;
</script>
4、后台实现方法
后台实现方法：
在.aspx里添加<asp:Label id="Label1" Runat="server"></asp:Label>
在.cs里添加
** void InitializeComponent()
{
this.Repeater1.ItemDataBound += new System.Web.UI.WebControls.RepeaterItemEventHandler(this.Repeater1_ItemDataBound);
this.Load += new System.EventHandler(this.Page_Load);
** 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);
