我希望我的TabControl上的标签显示在左侧,有时是右侧 但是,与System.Windows.Forms.TabControl不同,我希望文本保持水平,而不是向水平方向旋转90度或270度。
虽然我可以在大约一两个小时内自己编写代码来执行此操作,但我只是想我会先询问是否存在实现此功能的Winforms控件。
NB:任何现有的解决方案最好都是非商业性的。
感谢。

我不知道这是多么强大,我不能声称创造它但是... http://www.dreamincode.net/forums/topic/125792-how-to-make-vertical-tabs/
这是一种做法。
首先,我们将通过设置属性
将其对齐方式更改为Left对齐=左
如果你打开了XP主题,那么你可能会注意到Tab Control的奇怪布局。别担心,我们会把它弄好。
您可能已经注意到Tabs是垂直的,我们的要求是水平的。所以我们可以改变Tabs的大小。但在我们这样做之前,我们必须将SizeMode属性设置为
SizeMode =固定
现在我们可以使用ItemSize属性
来更改大小ItemSize = 30,120 宽度= 30,高度= 120
设置Alignment = Left后,Tab控件旋转Tabs,导致宽度和高度似乎相反。这就是为什么当我们增加高度时,我们看到宽度增加,当我们增加宽度时,高度就会受到影响。
现在Text也会显示,但是垂直显示。不幸的是,没有简单的方法来解决这个问题。为此,我们必须自己编写文本。为此,我们将首先设置DrawMode
DrawMode = OwnerDrawFixed
01
Private Sub TabControl1_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles TabControl1.DrawItem
Dim g As Graphics
Dim sText As String
Dim iX As Integer
Dim iY As Integer
Dim sizeText As SizeF
Dim ctlTab As TabControl
ctlTab = CType(sender, TabControl)
g = e.Graphics
sText = ctlTab.TabPages(e.Index).Text
sizeText = g.MeasureString(sText, ctlTab.Font)
iX = e.Bounds.Left + 6
iY = e.Bounds.Top + (e.Bounds.Height - sizeText.Height) / 2
g.DrawString(sText, ctlTab.Font, Brushes.Black, iX, iY)
End Sub

Microsoft提供了一个教程,用于在MSDN上使用现有TabControl执行此操作,并在C#和Visual Basic .NET中提供示例代码。他们的方法基于使用所有者绘图。总结下面的步骤:
将TabControl的对齐属性设置为正确。
通过将 SizeMode 属性设置为固定,确保所有标签的横向宽度相同。
将 ItemSize 属性设置为标签的首选大小,请注意宽度和高度相反。
将 DrawMode 属性设置为 OwnerDrawFixed 。
为TabControl的 DrawItem 事件设置事件处理程序,并将所有者绘图代码放在那里,指示每个标签的显示方式。为方便起见,下面重现了它们的事件处理程序的C#示例代码(假设您的TabControl名为tabControl1
:
private void tabControl1_DrawItem(Object sender, System.Windows.Forms.DrawItemEventArgs e)
{
Graphics g = e.Graphics;
Brush _textBrush;
// Get the item from the collection.
TabPage _tabPage = tabControl1.TabPages[e.Index];
// Get the real bounds for the tab rectangle.
Rectangle _tabBounds = tabControl1.GetTabRect(e.Index);
if (e.State == DrawItemState.Selected)
{
// Draw a different background color, and don't paint a focus rectangle.
_textBrush = new SolidBrush(Color.Red);
g.FillRectangle(Brushes.Gray, e.Bounds);
}
else
{
_textBrush = new System.Drawing.SolidBrush(e.ForeColor);
e.DrawBackground();
}
// Use our own font.
Font _tabFont = new Font("Arial", (float)10.0, FontStyle.Bold, GraphicsUnit.Pixel);
// Draw string. Center the text.
StringFormat _stringFlags = new StringFormat();
_stringFlags.Alignment = StringAlignment.Center;
_stringFlags.LineAlignment = StringAlignment.Center;
g.DrawString(_tabPage.Text, _tabFont, _textBrush, _tabBounds, new StringFormat(_stringFlags));
}
您可以尝试使用上述代码中的ItemSize
属性和_tabFont
值来微调您的标签'满足你的需要。对于更漂亮的造型,我建议以this other MSDN article作为起点。

这是一个老问题,但是我发现了一个漂亮的C#类。添加普通的WinForms选项卡控件之后。将此作为类DotNetBarTabControl.cs
添加到项目中,然后确保将Winforms选项卡控件替换为该类。
this.tabControl1 = new System.Windows.Forms.TabControl();
必须更改为:
this.tabControl1 = new TabControls.DotNetBarTabControl();
private System.Windows.Forms.TabControl tabControl1;
必须更改为:
private TabControls.DotNetBarTabControl tabControl1;
