C# winformTextBox 键盘监听
Step 1：添加监听
- 方式1：Designer中添加监听
this.textBox1.Location = new System.Drawing.Point(12, 5); this.textBox1.Multiline = true; this.textBox1.Name = "textBox1"; this.textBox1.Size = new System.Drawing.Size(548, 188); this.textBox1.TabIndex = 0; this.textBox1.TextChanged += new System.EventHandler(this.textBox1_TextChanged); this.textBox1.KeyDown += new System.Windows.Forms.KeyEventHandler(this.textBox1_KeyDown);//添加键盘事件
- 方式2：CS代码里添加监听
public Form1()
{
InitializeComponent();
textBox1.TextChanged += new EventHandler(textBox1_TextChanged);
textBox1.KeyDown+=new KeyEventHandler(textBox1_KeyDown);//添加键盘事件
}
Step 2 : 监听事件
示例：
- 添加Ctrl+A 全选事件
/// <summary>
/// 控件事件
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void textBox1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
if (e.KeyCode == Keys.A && e.Control)
{
textBox1.SelectAll();
}
}
