C# 如何在codebehind c中从中继器向UserControl传递参数#

我需要循环一个集合，并将值传递给UserControl。它是动态的，我不知道如何传递参数值。我用的是中继器

<asp:Repeater runat="server" id="Repeater1">
  <ItemTemplate>
     <uc1:testControl ID="testControl1" runat="server"   />
  </ItemTemplate>
</asp:Repeater>

任何帮助都将不胜感激！感谢向事件添加事件处理程序…

ASPX代码：

<asp:Repeater runat="server" id="Repeater1" OnItemDataBound="Repeater1_ItemDataBound">
    <ItemTemplate> 
        <uc1:testControl ID="testControl1" runat="server" /> 
    </ItemTemplate > 
</asp:Repeater>

您可以通过更简单的方式实现这一点：

<asp:DataList RepeatLayout="Table" RepeatColumns="2" RepeatDirection="Horizontal" runat="server" ID="dl">
            <ItemTemplate>              
                <uc1:UCGroup ID="UCGroup1" runat="server" Title=<%# DataBinder.Eval(Container.DataItem, "RecipientGroup.Name") %> />

                    <div class="template_over"> 
                        <a href="/ScheduleCampaign/<%# DataBinder.Eval(Container.DataItem, "RecipientGroup.Name") %>">

                      <%# DataBinder.Eval(Container.DataItem, "Email") %>

                    </a>
                    </div>
              </ItemTemplate>               
            </asp:DataList>

控件的代码：

<asp:Label ID="lbltitle" runat="server"></asp:Label>

public分部类UCGroup:System.Web.UI.UserControl
{
公共字符串标题{get；set；}
公共列表收件人{get；set；}
受保护的无效页面加载（对象发送方、事件参数e）
{
this.lbltitle.Text=标题；
this.rpRecipients.DataSource=收件人；
this.rpRecipients.DataBind（）；
}
}

不确定原因，但上面的代码框完全失败了。我试着粘贴我的转发器代码，键入它，将它用引号括起来，并在其周围放置代码标签。失败。你可以突出显示代码并按下{}按钮。伙计，这让我发疯了。谢谢你的信息，贾斯汀！
