Vertical Tab Control with horizontal text in Winforms
Solution 1
I don't know how robust this is and I can't claim to have created it but... http://www.dreamincode.net/forums/topic/125792-how-to-make-vertical-tabs/
Here's a way of doing it.
So first we are going to change its alignment to Left, by setting the property:
Alignment = Left
If you have XP themes turned on then you may notice the weird layout of Tab Control. Don't worry we will make it fine.
As you may have noticed that Tabs are vertical, and our requirement is horizontal. So we can change the size of Tabs. But before we can do this we have to set the SizeMode property as,
SizeMode = Fixed
Now we can change the size by using the ItemSize property,
ItemSize = 30, 120 Width = 30 and Height = 120
After setting the Alignment = Left, Tab control rotates the Tabs which causes the Width and Height seem to be reversed. That is why when we increase Height, we see that width is increasing and when we increase width the height is effected.
Now Text will also be displaying, but vertically. Unfortunately there is no simple way to resolve this issue. For this purpose we have to write the Text by ourselves. To do this we will first set the 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

This is the code for a custom tab control that I'm quite fond of. You will need to copy and paste this code into a new class then rebuild the project. You will see a new custom user control displayed in your toolbox.
Imports System.Drawing.Drawing2D
Class DotNetBarTabcontrol
Inherits TabControl

SetStyle(ControlStyles.AllPaintingInWmPaint Or ControlStyles.ResizeRedraw Or ControlStyles.UserPaint Or ControlStyles.DoubleBuffer, True)
DoubleBuffered = True
SizeMode = TabSizeMode.Fixed
ItemSize = New Size(44, 136)
End Sub
Protected Overrides Sub CreateHandle()
MyBase.CreateHandle()
Alignment = TabAlignment.Left
End Sub
Function ToPen(ByVal color As Color) As Pen
Return New Pen(color)
End Function
Function ToBrush(ByVal color As Color) As Brush
Return New SolidBrush(color)
End Function

Dim G As Graphics = Graphics.FromImage(B)
Try : SelectedTab.BackColor = Color.White : Catch : End Try

This is an old question but I found a good looking C# class. After adding the normal WinForms tab control. Add this to your project as a class E.G DotNetBarTabControl.cs
Then make sure to replace the Winforms tab controls to this class.
-
this.tabControl1 = new System.Windows.Forms.TabControl();
must be changed to:
this.tabControl1 = new TabControls.DotNetBarTabControl();
-
private System.Windows.Forms.TabControl tabControl1;

You can have fun making a dark theme to. In the photo Form2 uses the material skin. It can be found on NuGet as well.

I have decided to share the code I developed since some people, such as Amit Andharia, would like to benefit from it.
This is the result after I had implemented Rob P.'s answer.
Release Notes:
- Full design time support
- Automatic resizing of tabs (up to 128px wide)
- Tab icons implemented
- Unused properties have been hidden
The code can be downloaded from here.
Solution 5
There is a tutorial provided by Microsoft for doing this with the existing TabControl on MSDN, with sample code given in both C# and Visual Basic .NET. Their method is based on using owner drawing. Summarizing their steps below:
Set the TabControl's Alignment property to Right.
Ensure all tabs are the same horizontal width by setting the SizeMode property to Fixed.
Set the ItemSize property to your preferred size for the tabs, keeping in mind that the width and height are reversed.
Set the DrawMode property to OwnerDrawFixed.
-
Set up an event handler for the TabControl's DrawItem event, and place your owner drawing code in there dictating how each tab should be displayed. Their C# sample code for the event handler is reproduced below for convenience (it assumes your TabControl is named
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)); }
You can probably experiment with your ItemSize
property and the _tabFont
value from the above code to fine-tune your tabs' appearance to whatever you need. For even fancier styling, I'd recommend looking at this other MSDN article as a starting point.

Alex Essilfie about 4 years
I would like to have the tabs on my TabControl displayed on the left, or sometimes right.
Unlike the System.Windows.Forms.TabControl, however, I would like the text to remain horizontal instead of being rotated by 90 or 270 degrees to the horizontal.Here are a couple of pictures illustrating the concept
Though I could write code to do this myself in about an hour or two, I just thought I'd ask first if there is any existing Winforms control that implements such feature.
NB: Any existing solution should preferably be non-commercial.
Thanks.
-
Alex Essilfie over 12 yearsThanks for the help. I tweaked the code a bit but it wasn't as long as it would taken to write a new control from scratch.
-
Amit Andharia over 9 years@AlexEssilfie did you made it look exactly same as screenshots you've included? if so, can you share the code?
-
Alex Essilfie over 9 years@AmitAndharia: I did not desire it to be exactly as shown in the screenshots but I was able to get it to work well enough for me. I'll upload my code later today or within three days max in the interest of the wider community.
-
Amit Andharia over 9 years@AlexEssilfie I'll be waiting to look at it. Actually i've an urgent assignment which requires it, if you can share today, that would be gr8 help.
-
Alex Essilfie over 9 years@AmitAndharia: I have uploaded the code. See my answer for details.
-
Amit Andharia over 9 yearsThanks Alex. I've been actually thinking it would be similar to the screenshot you posted and hence was interested in looking at code, regardless, code you shared is really helpful.
-
Alex Essilfie over 9 years@AmitAndharia: I wrote one that replicates the Visual Studio style but I unfortunately lost that code so I had to bug-fix this one and pack it into a
.vb
file for use. If you so desire, I could reimplement the VS-style one but I can't assure you of getting it very soon. -
Amit Andharia over 9 yearsThanks that would be gr8 if you can do something similar and share.
-
Alex Essilfie almost 9 years@dahsra I didn't write a C# version. I'll have to work on that conversion and provide you with the link in a day or two.
-
Alex Essilfie about 7 yearsDid you read the answer by Rob P.? You have repeated the exact same thing almost six years after he posted his answer.
-
Knowledge Cube about 7 years@AlexEssilfie I wouldn't say exactly the same. First, my provided code is in C#, whereas his was provided in VB.NET. Second, I'm using MSDN as my source as opposed to a forum post from elsewhere, so I imagine the version of the code I'm presenting is more likely to represent best practices for approaching this. Third, there are subtle differences in the code if you care to look (using
GetTabRect()
instead ofe.Bounds
, code to account for selected states, etc.). Basically, I posted my answer because I believed the information I had to share was more complete and of higher quality. -

DrBB over 3 yearsThere are a lot of missing Dispose() calls which need to be added. I translated this to C# and it leaked everywhere. StringFormat, Font, Pen, Brush all need to have Dispose() called.
