在asp.net中为Web用户控件添加属性和事件(5) <asp:DropDownList id="DropDownList1" runat="server" AutoPostBack="True">
<asp:ListItem Value="0" Selected="True">中文</asp:ListItem>
<asp:ListItem Value="1">英文</asp:ListItem>
</asp:DropDownList></FONT>
</form>
</body>
</HTML>
在后台代码中添加事件和属性。
虽然在前台添加了LogInOutControl1，但是后台代码中不会生成protected LogInOutControl LogInOutControl1;这条语句，我觉得很奇怪，不管先加上他。
接着在Page_Load事件中注册LogInOutClick事件：
this.LogInOutControl1.LogInOutClick += new LogInOutClickHandler(LogInOutControl1_LogInOutClick);
完整代码如下：
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
namespace ZZ
{
public class Default : System.Web.UI.Page
{
protected System.Web.UI.WebControls.Label LabelMsg;
protected System.Web.UI.WebControls.DropDownList DropDownList1;
protected LogInOutControl LogInOutControl1;
private void Page_Load(object sender, System.EventArgs e)
{
//注册用户控件事件
this.LogInOutControl1.LogInOutClick += new LogInOutClickHandler(LogInOutControl1_LogInOutClick);
}
#region Web 窗体设计器生成的代码
override protected void OnInit(EventArgs e)
{
InitializeComponent();
base.OnInit(e);
}
private void InitializeComponent()
{
this.DropDownList1.SelectedIndexChanged += new System.EventHandler(this.DropDownList1_SelectedIndexChanged);
this.Load += new System.EventHandler(this.Page_Load);
}
#endregion
private void LogInOutControl1_LogInOutClick(object sender, LogInOutEventArgs e)
