为什么都不执行？

namespace MenuSample
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void textBox1_TextChanged(object sender, EventArgs e)
{
MessageBox.Show("有改变哦！");
}

private void button1_Click(object sender, EventArgs e)
{

}

private void textBox1_TextChanged_1(object sender, EventArgs e)
{

}
private void texyBox1_KeyPress(object senter, KeyPressEventArgs e)
{
MessageBox.Show("您操作的键盘");
}
}
}

TextChange和KeyPress 都没有执行，是哪里错了？谢谢

看下你的textBox加的事件是否是这几个

[huwei12345]

有没有绑定到 textBox1 上哟？
textBox1_TextChanged :需要失去焦点

[江南小鱼]

textBox1 AutoPostBack属性设置为true

[qlzf11140820]

public partial class Form1 : Form 
    { 
        public Form1() 
        { 
            InitializeComponent(); 
      textBox1.KeyPress += new KeyPressEventHandler(textBox1_KeyPress);
            textBox1.TextChanged += new EventHandler(textBox1_TextChanged);
        } 

        private void textBox1_TextChanged(object sender, EventArgs e) 
        { 
            MessageBox.Show("有改变哦！"); 
        } 

        private void button1_Click(object sender, EventArgs e) 
        { 

        } 

        private void textBox1_TextChanged(object sender, EventArgs e) 
        { 

        } 
        private void texyBox1_KeyPress(object senter, KeyPressEventArgs e) 
        { 
            MessageBox.Show("您操作的键盘"); 
        } 
    } 

可能没注册事件

[qlzf11140820]

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
textBox1.KeyPress += new KeyPressEventHandler(textBox1_KeyPress);
textBox1.TextChanged += new EventHandler(textBox1_TextChanged);
}

private void textBox1_TextChanged(object sender, EventArgs e)
{
MessageBox.Show("有改变哦！");
}

private void button1_Click(object sender, EventArgs e)
{

}

private void textBox1_TextChanged(object sender, EventArgs e)
{

}
private void texyBox1_KeyPress(object senter, KeyPressEventArgs e)
{
MessageBox.Show("您操作的键盘");
}
}

没注册事件

教你一招，把它删除了，添加事件一次，我以前也遇到过这种情况。
