为自定义控件添加页面响应事件

ascx:



ascx.cs:

(1)

public delegate void PostBackDelegate();  //定义委托类型

public event PostBackDelegate PostBackEvent;  //定义委托对象

protected void Button1_Click(object sender, EventArgs e)

{

    if (this.PostBackEvent != null) this.PostBackEvent();  //无参数

}

(2)

public event EventHandler PostBackHandler;

protected void Button1_Click(object sender, EventArgs e)

{

    if (this.PostBackHandler != null) this.PostBackHandler(sender, e);  //有参数

}

aspx.cs:

在Page_Load里（不是!IsPostBack里）加入：

(1)

MyUserControl1.PostBackEvent += new Test_MyFilePath_MyUserControl.PostBackDelegate(MyFuncName);  //new自动生成

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 = "控件按钮名称";  //改变控件按钮名称

    Response.Write("ookk");

}
