尝试将tabcontrol的每个选项卡上的文本垂直显示。因为我从来没有进入过控制，什么不是，我有点陷入困境。找到一些代码来显示文本，就像它向左旋转一样。我希望它显示为好像它在选项卡上向右（垂直）旋转。骨架代码如下：
Protected Sub OnDrawItem(ByVal sender As Object, ByVal e As DrawItemEventArgs) Handles TabControl1.DrawItem
'MyBase.OnDrawItem(e)'
Dim tc As TabControl = DirectCast(sender, TabControl)
Dim g As Graphics = e.Graphics
Dim rectf As RectangleF
Dim isVertical As Boolean = (tc.Alignment > TabAlignment.Bottom)
Dim off As Integer = 1 : If (e.State And sel) = sel Then off = -1
Dim textFormat As New StringFormat(StringFormatFlags.NoClip _
Or StringFormatFlags.NoWrap)
With textFormat
.HotkeyPrefix = System.Drawing.Text.HotkeyPrefix.Show
.Alignment = StringAlignment.Center
.LineAlignment = StringAlignment.Center
End With
With e.Bounds
If isVertical Then
' tabs are aligned left or right'
If tc.Alignment = TabAlignment.Left Then
Dim m As New System.Drawing.Drawing2D.Matrix
m.Translate(0, .Height - tc.TabPages(0).Top)
m.RotateAt(270, New PointF(.X, .Y))
g.Transform = m
rectf = New RectangleF(.Left - tc.TabPages(0).Top, .Top + off, _
.Height, .Width)
ElseIf tc.Alignment = TabAlignment.Right Then
'Dim m As New System.Drawing.Drawing2D.Matrix'
'm.Translate(0, .Height - tc.TabPages(0).Top)'
'm.RotateAt(270, New PointF(.X, .Y))'
'g.Transform = m'
'rectf = New RectangleF(.Left - tc.TabPages(0).Top, .Top + off, _'
' .Height, .Width)'
' Here is where the tab should go to rotate the text about 180 degrees'
End If
Else
' tabs are aligned top or bottom'
rectf = New RectangleF(.X, .Y + off, .Width, .Height)
End If
End With
Dim col As Color
Select Case (e.State And notsf)
Case DrawItemState.Disabled
col = SystemColors.GrayText
Case DrawItemState.HotLight
col = SystemColors.HotTrack
Case Else
col = SystemColors.MenuText
End Select
g.DrawString(tc.TabPages(e.Index).Text, _
tc.Font, _
New SolidBrush(col), _
rectf, _
textFormat)
If isVertical Then g.ResetTransform()
If (e.State And selfoc) = selfoc Then
ControlPaint.DrawFocusRectangle(g, _
[Rectangle].Inflate(e.Bounds, -1, -1))
End If
textFormat.Dispose()
End Sub

我假设您正在使用XAML，这可以通过样式实现
添加以下样式：

然后您可以将其分配给每个标签项：
<controls:TabControl TabStripPlacement="Right" Margin="4">
<controls:TabItem Header="First" Style="{StaticResource TabItemStyle}">
<controls:TreeView>
<controls:TreeViewItem Header="Parent 1" />
<controls:TreeViewItem Header="Parent 2">
<controls:TreeViewItem Header="Child 1">
<controls:TreeViewItem Header="Grandchild 1" />
</controls:TreeViewItem>
</controls:TreeViewItem>
<controls:TreeViewItem Header="Parent 3">
<controls:TreeViewItem Header="Child 1">
<controls:TreeViewItem Header="Grandchild 1" />
<controls:TreeViewItem Header="Grandchild 2" />
</controls:TreeViewItem>
</controls:TreeViewItem>
</controls:TreeView>
</controls:TabItem>
<controls:TabItem Header="Second" Style="{StaticResource TabItemStyle}">
<controls:TreeView>
<controls:TreeViewItem Header="Parent 1" />
<controls:TreeViewItem Header="Parent 2">
<controls:TreeViewItem Header="Child 1">
<controls:TreeViewItem Header="Grandchild 1" />
</controls:TreeViewItem>
</controls:TreeViewItem>
<controls:TreeViewItem Header="Parent 3">
<controls:TreeViewItem Header="Child 1">
<controls:TreeViewItem Header="Grandchild 1" />
<controls:TreeViewItem Header="Grandchild 2" />
</controls:TreeViewItem>
</controls:TreeViewItem>
<controls:TreeViewItem Header="Parent 4">
<controls:TreeViewItem Header="Child 1">
<controls:TreeViewItem Header="Grandchild 1" />
<controls:TreeViewItem Header="Grandchild 2" />
<controls:TreeViewItem Header="Grandchild 3" />
<controls:TreeViewItem Header="Grandchild 4" />
<controls:TreeViewItem Header="Grandchild 5" />
<controls:TreeViewItem Header="Grandchild 6" />
<controls:TreeViewItem Header="Grandchild 7" />
<controls:TreeViewItem Header="Grandchild 8" />
</controls:TreeViewItem>
</controls:TreeViewItem>
</controls:TreeView>
</controls:TabItem>
</controls:TabControl>
现在您可以从顶部/底部/右侧/左侧更改，文本将在右侧/左侧垂直。在这个例子中我单独留下了顶部和底部，但这应该给你很多关于如何控制这些标签的想法。
答案 1 :(得分：0)
我不使用VB或WinForms，因此以下内容不会出现在代码中并包含一些猜测。如果没有截图，很难知道你的描述与你想要的有什么不同。我是否正确地认为您只是希望标签的标题文本以另一种方式旋转180度，即文本的“顶部”对齐标签的左侧或标签的右侧，哪一个不是现在？
在分支If tc.Alignment = TabAlignment.Right Then ...中，您的文字正在通过RotateAt调用旋转：
m.RotateAt(270, New PointF(.X, .Y))
并且您需要将270更改为90以使文本在另一个方向上旋转。
（您是否熟悉如此设置转换矩阵？相同的原则适用于OpenGL或DirectX编程。如果没有，请注释，我将解释/链接。）
如果您只是这样做，那么文本将无法显示，因为它将被旋转到关闭您正在绘制的位图。您需要翻译它，以便文本的开头位于右上角。这就是我上面提到的猜测所在：我不熟悉你正在使用的图形框架的坐标系，所以我不知道要翻译哪个方向。对不起，我不能给你工作代码，但我只是没有Visual Studio和.Net Winforms控件来试验:)我可以看到你已经在这些方面做了一些事情：
m.Translate(0, .Height - tc.TabPages(0).Top)
我的猜测是您需要更改此设置，以便X坐标（0）为.Width或.Width - [text height, calculate this]，您可能还需要考虑Y坐标中的文本宽度。 （文本“高度”和“宽度”就好像文本是水平/正常绘制的。）我很确定.Net的绘图框架可能包括Graphics TextHeight(...)和TextWidth(...)方法如果它不是那些名字我肯定很容易找到:) TextRect()也许？
（如果我坐在你的电脑上并试图通过纯粹的猜测来解决这个问题，我会编写这个代码，以便在大位图的正中间旋转文本，修改它，使其位于位于矩形内部的正确位置的一个选项卡大小的位图，然后将代码移动到选项卡绘制方法。省去了一个小小的选项卡并运行它的所有麻烦并且当它不可见时“我的文本在哪里？”它被绘制在错误的坐标处。）
