Question

我需要一些方法来隐藏TabControl的标题（我将以编程方式切换选定的标签）。我怎么能这样做？

Answer 1

前一段时间我有同样的要求。我的解决方案比Stefan的解决方案简单一些。

        tabControl.ItemSize = new Size(0, 1);
        tabControl.SizeMode = TabSizeMode.Fixed;

虽然高度设置为1像素，但当您使用TabSizeMode.Fixed时，标题实际上会完全消失。

这对我来说效果很好。

将tabcontrol放在面板中并固定它，使其隐藏标题。最简单的方法是在后面的代码中执行此操作（或创建执行此操作的自定义控件）：

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Dim bordersize As Integer = 3 'could'nt find this on the control.

    Dim ControlSize As New Size(437, 303) ' the size you want for the tabcontrol
    Dim ControlLocation As New Point(10, 10) 'location

    Dim p As New Panel
    p.Size = ControlSize
    p.Location = ControlLocation
    Me.Controls.Add(p)

    Dim t As New TabControl
    t.Size = ControlSize
    p.Controls.Add(t)



    t.Left = -t.Padding.Y
    t.Top = -(t.ItemSize.Height + t.Padding.Y)
    p.Width = t.Width - t.Padding.X
    p.Height = t.Height - (t.ItemSize.Height + t.Padding.Y + bordersize)
    t.Anchor = AnchorStyles.Bottom Or AnchorStyles.Left Or AnchorStyles.Right Or AnchorStyles.Top

    AddHandler t.GotFocus, AddressOf ignoreFocus
End Sub

Private Sub ignoreFocus(ByVal sender As Object, ByVal e As System.EventArgs)
    Dim t As TabControl = CType(sender, TabControl)
    If t.SelectedIndex > -1 Then t.TabPages(t.SelectedIndex).Focus()
End Sub

现在，如果您调整面板大小，tabcontrol将会跟随并仅显示标签页区域。

根据您的需要，您可能还会考虑使用MultiView的WinForms版本：

Public Class MultiView
  Inherits Panel

  Public Property SelectedIndex As Integer
    Get
      Return _SelectedIndex
    End Get
    Set(Value As Integer)
      If Value.IsBetween(-1, Me.Controls.Count, InclusionOptions.Exclusive) Then
        Me.SelectView(Me.Controls(Value))
      Else
        _SelectedIndex = -1
      End If
    End Set
  End Property
  Private _SelectedIndex As Integer = -1



  Public Property SelectedView As UserControl
    Get
      Return _SelectedView
    End Get
    Set(Value As UserControl)
      If Value IsNot Nothing Then
        Me.SelectView(Value)
      End If
    End Set
  End Property
  Private _SelectedView As UserControl



  Default Public ReadOnly Property Item(Index As Integer) As UserControl
    Get
      Return Me.Views(Index)
    End Get
  End Property



  Default Public ReadOnly Property Item(Name As String) As UserControl
    Get
      Return Me.Views.Where(Function(View As UserControl)
                              Return View.Name.ToLower = Name.ToLower
                            End Function).SingleOrDefault
    End Get
  End Property



  Public ReadOnly Property Views As List(Of UserControl)
    Get
      Return Me.Controls.Cast(Of UserControl).ToList
    End Get
  End Property



  Public Sub AddView(View As UserControl)
    Me.Controls.Add(View)
    View.Dock = DockStyle.Fill
  End Sub



  Private Sub SelectView(NewView As UserControl)
    Me.Controls.Cast(Of UserControl).ToList.ForEach(Sub(OldView As UserControl)
                                                      OldView.Visible = OldView Is NewView

                                                      If OldView Is NewView Then
                                                        OldView.Visible = True
                                                        _SelectedView = OldView
                                                        _SelectedIndex = Me.Controls.IndexOf(_SelectedView)
                                                      Else
                                                        OldView.Visible = False
                                                      End If
                                                    End Sub)
  End Sub
End Class

删除或添加TabPage

    void Toggle()
    {
        if (tabControl1.TabPages.Contains(tabPage1))
            tabControl1.TabPages.Remove(tabPage1);
        else
            tabControl1.TabPages.Add(tabPage1);
    }

如果您想指定位置，请选择使用TabPages.Insert(index, tabPage)。
