asp.net（C#）中Repeater嵌套绑定Repeater

本文主要是介绍asp.net（C#）中Repeater嵌套绑定Repeater，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Repeater嵌套Repeater的结构：一般写过的都能看懂吧

    private void RpTypeBind()
{
//GetQuestionTypeAndCount() 返回一个datatable
this.rptypelist.DataSource = LiftQuestionCtr.GetQuestionTypeAndCount();
this.rptypelist.DataBind();
}
protected void rptypelist_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("rpquestionlist") as Repeater;//找到里层的repeater对象
DataRowView rowv = (DataRowView)e.Item.DataItem;//找到分类Repeater关联的数据项 
int typeid = Convert.ToInt32(rowv["qtid"]); //获取填充子类的id 
rep.DataSource = LiftQuestionCtr.GetSomeQuestionsByTypeid(typeid, 2);
rep.DataBind();
}
}

 

<table border="0" cellpadding="0" cellspacing="0" style="margin-bottom: 5px" width="100%">
<asp:Repeater runat="server" ID="rptypelist" OnItemDataBound="rptypelist_ItemDataBound">
<ItemTemplate>
<tr>
<td class="fb">
<a href="Lists.aspx?Qtid=<%#Eval("qtid") %>"><%#Eval("qtypename") %></a> <span id="askCount_15"
class="date2">[<%#Eval("typecount")%>]</span>
</td>
</tr>
<tr>
<td>
<div id="askTop2_15" class="ask_list">
<asp:Repeater runat="server" ID="rpquestionlist">
<ItemTemplate>
<a href="Question.aspx?qid=<%#Eval("liftquestionid")%>">
<%#Eval("questiontitle")%></a><br />
</ItemTemplate>
</asp:Repeater>
</div>
</td>
</tr>
</ItemTemplate>
</asp:Repeater>
</table>
