C#中如何实现用户控件的键盘事件？
紧急，各位帮帮忙 --------------------编程问答-------------------- Keypress? --------------------编程问答-------------------- 你在界面上丢下这个控件 它的事件里面没有？如果没有就去自定义控件里面重新写吧 --------------------编程问答-------------------- KeyPress 和 KeyDown 都可以吧 --------------------编程问答-------------------- KeyPress 和 KeyDown
这个事件先判断用户按键操作 如
private void cboShow_KeyPress(object sender, KeyPressEventArgs e)
{
e.Handled = e.KeyChar < '0' || e.KeyChar > '9';
if (e.KeyChar == (char)8)
{
e.Handled = false;
}
} --------------------编程问答--------------------
+1 --------------------编程问答-------------------- 首先把窗体的keypreview属性设置为true
然后在keyDown事件里写
--------------------编程问答-------------------- 首先把窗体的keypreview属性设置为true
/// <summary>
/// 键盘事件
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void PhotoForm_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.F2) //保存按钮快捷键
{
this.btnSave_Click(sender, e);
}
else if (e.KeyCode == Keys.F3) //重置按钮快捷键
{
this.btnReset_Click(sender, e);
}
else if (e.KeyCode == Keys.F5) //复制上条记录快捷键
{
this.btnCopy_Click(sender, e);
}
else if (e.KeyCode == Keys.F12) //浏览记录快捷键
{
this.btnLiulan_Click(sender, e);
}
else if (e.KeyCode == Keys.Escape) //退出按钮的快捷键
{
this.Close();
}
}
这是属性是必须设置的
然后在keyDown事件里写
