设置服务器控件的客户端属性的两个函数

1. Page.RegisterRequiresPostBack[概述[/b]] 将控件注册为需要回发处理的控件。[定义[/b]]public void RegisterRequiresPostBack( Control control);[参数[/b]] control 要注册的控件。[例子[/b]]void Text_Change(object sender, EventArgs e)
{
myLabel.Text = "<b>Welcome " + myTextBox.Text + " to ASP.NET</b>";
}
void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
this.RegisterRequiresPostBack(myTextBox);
}

2．Page.RegisterRequiresRaiseEvent
[定义[/b]] public virtual void RegisterRequiresRaiseEvent( IPostBackEventHandler control);[参数[/b]]control 要注册的控件。[备注[/b]]每个 Page 请求只能注册一个服务器控件。[例子[/b]]
void DisplayUserName(Object sender, EventArgs ea)
{
Response.Write("Welcome to " + userName.Text);
}
void RaiseEvent(Object sender, EventArgs ea)
{
// Raise a post back event for a control.
this.RaisePostBackEvent(userButton, "");
}
void Page_Load(Object sender, EventArgs ea)
{
// Register a control as one that requires postback handling.
this.RegisterRequiresRaiseEvent(userButton);
}
