如何從Repeater在代碼隱藏中將參數傳遞給UserControl c＃

Question

我需要遍歷集合並將值傳遞給UserControl。它是動態的，我不知道如何傳遞參數值。我正在使用中繼器。

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

在後面的代碼：

Repeater1.DataSource = _myCollection; 
       Repeater1.DataBind(); 

任何幫助將不勝感激！由於

Answer 1

ASPX代碼：

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

代碼隱藏：

protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e) 
{ 
    testControl ctrl = e.Item.FindControl("testControl1") as testControl; 

    if (ctrl != null) 
     ctrl.MyParameterName = "Foo"; 
}

事件處理程序添加到Repeater.ItemDataBound事件......

可以實現在一個更簡單的方式：

<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>

public partial class ChooseGroup : System.Web.UI.Page 
{ 
    protected void Page_Load(object sender, EventArgs e) 
    { 
     dl.DataSource = GroupsHndlr.GetExtendedRecipients(MySession.Current.ClientId); 
     dl.DataBind(); 
    } 
}

控件的代碼：

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

<asp:Repeater ID="rpRecipients" runat="server"> 
    <ItemTemplate> 
     1 
     </ItemTemplate> 
</asp:Repeater>

public partial class UCGroup : System.Web.UI.UserControl 
{ 
    public string Title { get; set; } 
    public List<string> Recipients { get; set; } 
    protected void Page_Load(object sender, EventArgs e) 
    { 
     this.lbltitle.Text = Title; 
     this.rpRecipients.DataSource = Recipients; 
     this.rpRecipients.DataBind(); 
    }
