使enter键的行为类似于窗体上的tab键

使用winforms时,应将Form KeyPreview属性设置为true

在窗体的按键事件中

private void Form1_KeyPress(object sender, KeyPressEventArgs e)
{
    if (e.KeyChar == 13)
       GetNextControl(ActiveControl, true).Focus();
}

Public Class MyCustomDataGrid
    Inherits DataGridView

    Protected Overrides Sub OnKeyUp(ByVal e As System.Windows.Forms.KeyEventArgs)
        If e.KeyCode = Keys.Enter Then
            e.Handled = True
            Me.ProcessTabKey(Keys.Tab)
        Else
            MyBase.OnKeyUp(e)
        End If
    End Sub
End Class

在尝试通过datagrid单元格进行制表时,会将enter键作为制表键进行处理, 如果你还需要处理表单上的tab,你必须按照Marioh所说的去做,但要做一点改变。

Protected Overrides Sub OnKeyUp(ByVal e As System.Windows.Forms.KeyEventArgs)
        If e.KeyCode = Keys.Enter AndAlso Not ActiveControl.GetType() Is GetType(Class1) Then
            e.Handled = True
            Me.ProcessTabKey(Not e.Shift)
        Else
            MyBase.OnKeyUp(e)
        End If
    End Sub

您只需添加对活动控件类型的检查,否则表单将停止自定义datagrid选项卡代码的工作。

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
Keys keyPressed = (Keys)msg.WParam.ToInt32();
switch (keyPressed)
{
    case Keys.Enter:
    case Keys.Tab:
        Control ctrl = this.GetNextControl(this.ActiveControl, true);
        while (ctrl is TextBox == false) 
        {
            ctrl = this.GetNextControl(ctrl, true);
        }
        ctrl.Focus();
        return true;
    default:
        return base.ProcessCmdKey(ref msg, keyData);
}
}
