asp.net repeater嵌套

OnItemCreated方式

 <%-- 一级Repeater绑定班级信息 --%>
 <asp:Repeater ID="rptClassInfo" runat="server" OnItemCreated="rptClassInfo_ItemCreated">
     <ItemTemplate>
         <div class="classInfo">
             <h3><%# Eval("ClassName") %></h3>
             <div class="stuInfo">
                 <ul class="title">
                     <li>姓名</li>
                     <li>性别</li>
                     <li>年龄</li>
                 </ul>
                 <%-- 二级Repeater绑定学生信息 --%>

                             <%-- 根据单双行增加样式 --%>

后端代码

  {
      BindClassInfo();
  }

  /// </summary>

直接嵌套

 <%-- 一级Repeater绑定班级信息 --%>
 <asp:Repeater ID="rptClassInfo" runat="server">
     <ItemTemplate>
         <div class="classInfo">
             <h3><%# Eval("ClassName") %></h3>
             <div class="stuInfo">
                 <ul class="title">
                     <li>姓名</li>
                     <li>性别</li>
                     <li>年龄</li>
                 </ul>
                 <%-- 二级Repeater绑定学生信息 --%>
                 <asp:Repeater ID="rptStudentInfo" runat="server" DataSource='<%#Eval("StudentList") %>'>
                     <ItemTemplate>
                         <ul class="<%# Container.ItemIndex%2==0?"cor1":"cor2" %>">
                             <%-- 根据单双行增加样式 --%>
                             <li><%# DataBinder.Eval(Container.DataItem,"Name") %></li>
                             <li><%# DataBinder.Eval(Container.DataItem,"Sex") %></li>
                             <li><%# DataBinder.Eval(Container.DataItem,"Age") %></li>
                         </ul>
                     </ItemTemplate>
                 </asp:Repeater>
             </div>
         </div>
     </ItemTemplate>
 </asp:Repeater>

后端代码

 protected void Page_Load(object sender, EventArgs e)
 {
     BindClassInfo();
 }

 /// <summary>
 /// 绑定班级信息(一级Repeater)
 /// </summary>
 public void BindClassInfo()
 {
     //获取所有班级信息
     List<ClassInfo> classInfoList = ClassInfo.GetClassInfoList();
     rptClassInfo.DataSource = classInfoList;
     rptClassInfo.DataBind();
 }

最终效果

方式1适合再次查找数据，比如再次查询数据库，方式2适合一次性查询出来直接绑定

字典和数组绑定

<asp:Repeater ID="dicBindRpt" runat="server">
    <ItemTemplate>
        <p>
            <span><%#Eval("key") %></span>
            <span><%#Eval("value") %></span>
        </p>
    </ItemTemplate>
</asp:Repeater>
<hr />
<asp:Repeater ID="arrayBindRpt" runat="server">
    <ItemTemplate>
        <p>
            <%#Container.DataItem %>
        </p>
    </ItemTemplate>
</asp:Repeater>

后端代码

var dic = new Dictionary<string, string>();
dic.Add("Name", "Nick");
dic.Add("Age", "13");
this.dicBindRpt.DataSource = dic;
this.dicBindRpt.DataBind();

var array = new string[]
{
    "张三",
    "李四",
    "王五"
};
this.arrayBindRpt.DataSource = array;
this.arrayBindRpt.DataBind();
