请问如何在一个控件的事件中调用另一个控件的事件？
我在控件listView1中增加了SelectedIndexChanged 事件
我想在控件button1的Click事件中调用listView1的SelectedIndexChanged 事件，请问如何做？
下面的语句虽然能执行，但是总是不对劲，有更好的方法吗？
private void button1_Click(object sender, System.EventArgs e)
{
listView1_SelectedIndexChanged(this,null);
}



using System;
using System.Drawing;
using System.Collections;

using System.Data;

{
public class Form1 : System.Windows.Forms.Form

private System.Windows.Forms.ListView listView1;
private System.ComponentModel.Container components = null;
public Form1()
{
InitializeComponent();
}

protected override void Dispose( bool disposing )
{
if( disposing )
{
if (components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
}

你的代码:
private void button1_Click(object sender, System.EventArgs e)
{
listView1_SelectedIndexChanged(this,null);
}
也没什么别扭的,本质上就是在调用一个私有的成员函数.
从设计上讲,你是不是考虑,独立出一个新的私有方法,
让button1_Click和liveView1_SelectIndexChanged 都来调用.
