基於中繼器的用戶控制

我開發基於中繼器的用戶控制。它必須包含預定義的 checkBox的每一行。基於中繼器的用戶控制

有什麼建議嗎？

你說的預定義是什麼意思？先生，需要多一點的時間繼續下去。 – 2011-04-19 07:19:54

每行必須包含複選框。 – Alexandre 2011-04-19 07:35:57

這沒有幫助。中繼器必須具有預定義的複選框和表格佈局。 – Alexandre 2011-05-09 06:47:38

您可以使用Repeater的ItemTemplate來放置必要的控件。下面是一個例子：

<asp: Repeater> 
     <ItemTemplate>  
       <asp:CheckBox ID="cbkWhatever" runat="server" Checked='<%# Eval("CbkDataField") %>' /> 
       All other items for Repeater ... 
     </ItemTemplate> 
</asp:Repeater>

也許，這樣的事情？

Default.aspx的

<%@ Page Language="C#" %> 
<script runat="server"> 
    protected override void CreateChildControls() 
    { 
     base.CreateChildControls(); 
     LoadUserControl(); 
    } 
    private void LoadUserControl() 
    { 
     ph.Controls.Clear(); 
     Control c = LoadControl("~/WebUserControl.ascx"); 
     c.ID = "foo"; 
     ph.Controls.Add(c); 
    } 
</script> 
<html> 
<body> 
    <form id="form1" runat="server"> 
    <div>
