绑定多个按钮到同一个事件
1.添加代码
private void clauseElementClicked(object sender, EventArgs e)
{undefined
textBoxWhereClause.SelectedText = ((Button)sender).Text;
}2.选择你要添加代码的控件
右键–属性–找到click这个事件，让后选择clauseElementClicked这个事件就可以了。
多个控件有同一个事件,优化
先自己声明方法,再用事件调用
public void borderS3D(object sender,EventArgs e)
{
((PictureBox)sender).BorderStyle=BorderStyle.Fixed3D;
} public void borderSNo(object sender, EventArgs e)
{
((PictureBox)sender).BorderStyle = BorderStyle.None;
}public FormMain()
{
InitializeComponent();
pictureBox1.MouseHover += new EventHandler(borderS3D);
pictureBox1.MouseLeave += new EventHandler(borderSNo);
pictureBox2.MouseHover += new EventHandler(borderS3D);
pictureBox2.MouseLeave += new EventHandler(borderSNo);
pictureBox3.MouseHover += new EventHandler(borderS3D);
pictureBox3.MouseLeave += new EventHandler(borderSNo);
pictureBox4.MouseHover += new EventHandler(borderS3D);
pictureBox4.MouseLeave += new EventHandler(borderSNo);
pictureBox5.MouseHover += new EventHandler(borderS3D);
pictureBox5.MouseLeave += new EventHandler(borderSNo);
pictureBox6.MouseHover += new EventHandler(borderS3D);
pictureBox6.MouseLeave += new EventHandler(borderSNo);
pictureBox7.MouseHover += new EventHandler(borderS3D);
pictureBox7.MouseLeave += new EventHandler(borderSNo);
pictureBox8.MouseHover += new EventHandler(borderS3D);
pictureBox8.MouseLeave += new EventHandler(borderSNo);
pictureBox9.MouseHover += new EventHandler(borderS3D);
pictureBox9.MouseLeave += new EventHandler(borderSNo);
pictureBox10.MouseHover += new EventHandler(borderS3D);
pictureBox10.MouseLeave += new EventHandler(borderSNo);
pictureBox11.MouseHover += new EventHandler(borderS3D);
pictureBox11.MouseLeave += new EventHandler(borderSNo);
}以上为个人经验，希望能给大家一个参考，也希望大家多多支持编程网。
