方法一：
protected override void OnKeyUp(System.Windows.Forms.KeyEventArgs e)
{
base.OnKeyUp(e);
if (e.KeyCode == System.Windows.Forms.Keys.Enter)
{
e.Handled = true;
System.Windows.Forms.SendKeys.Send("{TAB}");
}
}
protected override bool ProcessCmdKey(ref System.Windows.Forms.Message msg, System.Windows.Forms.Keys keyData)
{
switch (keyData)
{
case System.Windows.Forms.Keys.Enter:
{
System.Windows.Forms.SendKeys.Send("{TAB}");
}
return true;
}
return base.ProcessCmdKey(ref msg, keyData);
}
这样就能把捕捉到的回车事件转换成TAB事件
