ASP.NET2.0（C#）中如何实现多个控件事件共享，比如说多个Button控件共享一个事件，点击任何一个，都触发该事件！
急等高手！
------解决方案--------------------
void Page_Load(Object sender, EventArgs e)
{
Button1.Click += new EventHandler(this.GreetingBtn_Click);
Button2.Click += new EventHandler(this.GreetingBtn_Click);
Button3.Click += new EventHandler(this.GreetingBtn_Click);
}
void GreetingBtn_Click(Object sender,
EventArgs e)
{
// When the button is clicked,
// change the button text, and disable it.
Button clickedButton = (Button)sender;
clickedButton.Text = "...button clicked... ";
clickedButton.Enabled = false;
// Display the greeting label text.
GreetingLabel.Visible = true;
}
------解决方案--------------------
你可以分别在按钮的单击事件中调用另外一个方法
如
protected void button1_Click(Object sender, EventArgs e)
{
shareFunction(parameters);
}
protected void button2_Click(Object sender, EventArgs e)
{
shareFunction(parameters);
}
protected void shareFunction(parameters)
{
//相关处理
}
------解决方案--------------------
只要选择相同的事件处理程序即可
------解决方案--------------------
呵呵,ls够明了了.
