用戶控件

復制代碼代碼如下:

 
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="Ucone.ascx.cs" Inherits="UserControl_Ucone" %> 
<asp:TextBox ID="txtName" runat="server"></asp:TextBox> 
<asp:Button ID="btnAdd" runat="server" Text="Add" /> 
<input type="hidden" id="hid_html" name="hid_html" /> 
<div id="div_inner_input" runat="server"> 
</div> 

用戶控件后臺：

復制代碼代碼如下:

 
public partial class UserControl_Ucone : System.Web.UI.UserControl 
{ 
protected void Page_Load(object sender, EventArgs e) 
{ 
this.btnAdd.Attributes.Add("onclick", "return getAllCode_IE();"); 
} 
protected override void OnInit(EventArgs e) 
{ 
base.OnInit(e); 
this.btnAdd.Click += new EventHandler(btnAdd_Click); 
} 
void btnAdd_Click(object sender, EventArgs e) 
{ 
this.div_inner_input.InnerText = Request.Form["hid_html"].ToString(); 
} 
}
