ascx:
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
ascx.cs:
(1)
public delegate void PostBackDelegate();? //定義委托類型
public event PostBackDelegate PostBackEvent;? //定義委托對象
protected void Button1_Click(object sender, EventArgs e)
{
??? if (this.PostBackEvent != null) this.PostBackEvent();? //無參數
}
(2)
public event EventHandler PostBackHandler;
protected void Button1_Click(object sender, EventArgs e)
{
??? if (this.PostBackHandler != null) this.PostBackHandler(sender, e);? //有參數
}
aspx.cs:
在Page_Load里（不是!IsPostBack里）加入：
(1)
MyUserControl1.PostBackEvent += new Test_MyFilePath_MyUserControl.PostBackDelegate(MyFuncName);? //new自動生成
protected void MyFuncName()
{
??? Response.Write("OOKK");
}
(2)
MyUserControl1.PostBackHandler += new EventHandler(MyFuncName);
protected void MyFuncName(object sender, EventArgs e)
{
??? Button btn = (Button)sender;
??? btn.Text = "控件按鈕名稱";? //改變控件按鈕名稱
??? Response.Write("ookk");
}
