在vs.net中经常遇到事件丢失的问题,可以这样避免一下
方法一:
把InitializeComponent中的注册事件,如下
private void InitializeComponent()


{
this.DropDownList1.SelectedIndexChanged += new System.EventHandler(this.DropDownList1_SelectedIndexChanged);
this.Button1.Click += new System.EventHandler(this.Button1_Click); this.Load += new System.EventHandler(this.Page_Load);
}
剪切到override protected void OnInit(EventArgs e)里面,如下
override protected void OnInit(EventArgs e)


{
this.DropDownList1.SelectedIndexChanged += new System.EventHandler(this.DropDownList1_SelectedIndexChanged);
this.Button1.Click += new System.EventHandler(this.Button1_Click);
this.Load += new System.EventHandler(this.Page_Load);
}
方法二:
把InitializeComponent中的注册事件,如下
private void InitializeComponent()


{
this.DropDownList1.SelectedIndexChanged += new System.EventHandler(this.DropDownList1_SelectedIndexChanged);
this.Button1.Click += new System.EventHandler(this.Button1_Click);
this.Load += new System.EventHandler(this.Page_Load);
}
剪切到你的自定义方法中
private void LoadEvent()


{
this.DropDownList1.SelectedIndexChanged += new System.EventHandler(this.DropDownList1_SelectedIndexChanged);
this.Button1.Click += new System.EventHandler(this.Button1_Click);
this.Load += new System.EventHandler(this.Page_Load);
}
然后在pageload中调用自定义方法就可以了,如
private void Page_Load(object sender, System.EventArgs e)


{
if(!Page.IsPostBack)

{
LoadEvent();
}
}
每次需要注册方法时,就在刚才的剪切区注册就可以了,这样虽然麻烦一些,但是可以保证事件不会丢失。
