在表单和面板中使用 ENTER 或 RETURN 作为 TAB [英] Use ENTER or RETURN as TAB in form and panels

问题描述

我的表单是多个控件，例如 Textboxes 和 Panels，以及 Panels 中的 Textboxes，这会导致问题.我尝试使键 ENTER 和 RETURN 与 TAB 执行相同的操作，因此选择下一个控件，但出于未知原因，如果我从对面板的任何控件，它不会进入面板中的第一个控件，而是跳到下一个不是面板的控件.

My form as multiple controls like Textboxes and Panels, and Textboxes in Panels, which cause problem. I try to make keys ENTER and RETURN do the same as TAB, so select next control, but for an unknown reason if I i go from any control to a panel, it doesn't enter the first control in the panel, it skips to the next control which isn't a panel.

我的表单 key preview 已经是 True 并且我的标签索引没问题:第一个文本框是 10，第一个面板是 11，第一个文本框是面板 12.现在它跳到 20，下一个文本框不在面板中.

My form key preview is already True and my tab index are okay : First textbox is 10, first panel 11, first textbox of panel 12. For now it skips to 20, next textbox not in a panel.

基于这个问题的代码:Tab Key Functionality Using Enter键入 VB.Net

这是我的代码

Private Sub Values_KeyDown(ByVal sender As Control, 
  ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
    If e.KeyCode = Keys.Return Or e.KeyCode = Keys.Enter Then
        If TypeOf Me.GetNextControl(Me.ActiveControl, True) Is Panel Then
            Me.SelectNextControl(CType(Me.ActiveControl, Panel).Controls.Item(0), True, True, False, True)
        Else
            Me.SelectNextControl(Me.ActiveControl, True, True, False, True)
        End If
        e.Handled = True
    End If
End Sub

谢谢！

推荐答案

通过 Hans 的回答，我设法通过简单地将嵌套参数更改为 true 并摆脱了应该使其与面板一起工作的部分来使其工作，像这样:

With Hans' answer i manage to make it work by simply changing the nested parameter to true and get rid of the part that was suppose to make it work with panels, like this:

Private Sub Values_KeyDown(ByVal sender As Control, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
    If e.KeyCode = Keys.Return Or e.KeyCode = Keys.Enter Then
        Me.SelectNextControl(Me.ActiveControl, True, True, True, True)
        e.Handled = True
    End If
End Sub

您仍然需要将表单上的 Key Preview 参数设置为 True

You'll still need to put the Key Preview parameter on your form to True

我还在这里找到了替代方法:如何使 TextBox 上的 Enter 充当 TAB 按钮

I also found an alternative here : How to make Enter on a TextBox act as TAB button

Private Sub Values_KeyDown(ByVal sender As Control, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
    If e.KeyCode = Keys.Return Or e.KeyCode = Keys.Enter Then
        SendKeys.Send("{TAB}")
        e.Handled = True
    End If
End Sub
