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.
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.

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;
must be changed to:

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.
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.

I'm writing a simple application in c# .net core 6 and winform to "assemble" some pngs and write some text on it.
This is the Photoshop output. The Title "Baldur the invincible" is wrote in Diablo Light when i'm writing it with DrawString with Font("Diablo", 30, FontStyle.Regular)
and this is my output with the Font.
In photoshop i used Diablo Light font but in the list of system fonts, from C# code, i see just Diablo Regular.. and the result is different.
How i can set the fontweight ?
here some code:
// ---------------------------------------------------------------------------------------------- +
// All TEXT ------------------------------------------------------------------------------------- +
// ---------------------------------------------------------------------------------------------- +
{
//string familyName;
//string familyList = "";
//FontFamily[] fontFamilies;
//InstalledFontCollection installedFontCollection = new InstalledFontCollection();
//fontFamilies = installedFontCollection.Families;
Font title_font = new Font("Diablo", 30, FontStyle.Regular);
Font sub_font = new Font("Diablo", 25, FontStyle.Regular);
List<Font> list_fonts = new List<Font>();
list_fonts.Add(title_font);
list_fonts.Add(sub_font);
RectangleF tit_rect = new RectangleF(165, 70, w - (165 * 2), h);
//RectangleF sub_rect = new RectangleF(165, 82 + 30, w - (165 * 2), h);
var v = m_dict_titles["Title"];
string curr_string = tabbed_value[v].ToUpper();
float offsety = WriteTitleTextf2(map_back, 0, TL(curr_string, false), tit_rect, list_fonts, StringAlignment.Near, 5);
}
public void WriteOnBitmapf(Bitmap bmp, int col, Font font, String text, RectangleF rectf, StringAlignment st_align, float stringi = 0.0f)
{
float size = font.Size;
Graphics g = Graphics.FromImage(bmp);
g.SmoothingMode = SmoothingMode.AntiAlias;
g.InterpolationMode = InterpolationMode.HighQualityBicubic;
g.PixelOffsetMode = PixelOffsetMode.HighQuality;
g.TextRenderingHint = TextRenderingHint.AntiAliasGridFit;
StringFormat format = new StringFormat()
{
Alignment = st_align,
LineAlignment = StringAlignment.Near
};
Brush br = col == 0 ? new SolidBrush(Color.FromArgb(0, 0, 0)) : new SolidBrush(Color.FromArgb(255, 255, 255));
g.DrawString(text, font, br, rectf, format);
g.Flush();

I want to change the color of a selected item in a listbox to a specific ARGB value.
When it's not selected it's showing the ForeColor I've defined in the Properties of my listBox.
But whatever I try it's either setting the brush to a predefined color (white, green, whatever),
changing the color when selected & not selected for both in the same color...
or it's not changing at all.
The solutions I see on stackoverflow are XAML based, but I'm using Winforms C# .NET, so that's not an option.
I've managed to make a custom listBox already using OwnerDrawFixed as DrawMode and a custom DrawItem predefined like this:
{
SolidBrush myBrushBack = new SolidBrush(Color.FromArgb(255, 42, 42, 42));
SolidBrush myBrushFore = new SolidBrush(Color.FromArgb(255, 62, 182, 86));
if (e.Index < 0) return;
e.DrawBackground();
Graphics g = e.Graphics;
Brush brush = ((e.State & DrawItemState.Selected) == DrawItemState.Selected) ?
myBrushBack : new SolidBrush(e.BackColor);
myBrushFore : new SolidBrush(e.ForeColor);
g.FillRectangle(brush, e.Bounds);
SizeF size = e.Graphics.MeasureString(listBoxTracks.ToString(), e.Font);
e.Graphics.DrawString(listBoxTracks.Items[e.Index].ToString(), e.Font,
new SolidBrush(e.ForeColor), e.Bounds.Left + (e.Bounds.Width / 29 - size.Width / 39), e.Bounds.Top + (e.Bounds.Height / 2 - size.Height / 2), StringFormat.GenericDefault);
e.DrawFocusRectangle();
}
This code doesn't give me the right green I want + it changes the selected & not selected text color for both:
e.Graphics.DrawString(listBoxTracks.Items[e.Index].ToString(), e.Font, Brushes.Green, e.Bounds, StringFormat.GenericDefault);
How it is behaving now: https://imgur.com/a/VvhDjqQ
How I want it to behave: https://imgur.com/a/IqNT70p
Thanks to Jimi, I've adapted the code and it works correctly now, using the code like this:
{
if (e.Index < 0) return;
e.DrawBackground();
bool isItemSelected = ((e.State & DrawItemState.Selected) == DrawItemState.Selected);
using (SolidBrush bgBrush = new SolidBrush(isItemSelected ? Color.FromArgb(255, 42, 42, 42) : Color.FromArgb(255, 29, 29, 29)))
using (SolidBrush itemBrush = isItemSelected ? new SolidBrush(Color.FromArgb(255, 62, 182, 86)) : new SolidBrush(Color.FromArgb(255, 176, 176, 176)))
{
string itemText = listBoxTracks.GetItemText(listBoxTracks.Items[e.Index]);
e.Graphics.TextRenderingHint = TextRenderingHint.ClearTypeGridFit;
SizeF size = e.Graphics.MeasureString(listBoxTracks.ToString(), e.Font);
e.Graphics.FillRectangle(bgBrush, e.Bounds);
e.Graphics.DrawString(itemText, e.Font, itemBrush, e.Bounds.Left + (e.Bounds.Width / 29 - size.Width / 39), e.Bounds.Top + (e.Bounds.Height / 2 - size.Height / 2), StringFormat.GenericDefault);

I want to align the dynamic text on my progress bar.
Here is the code
using (var sf = new StringFormat()
{
Alignment = StringAlignment.Center,
LineAlignment = StringAlignment.Center,
}
)
progressBar1.CreateGraphics()
.DrawString(message, new Font("Arial", (float)8.25, FontStyle.Regular), Brushes.Black, new Rectangle(0, 0, 600, 480), sf);
The values 600,480 is the size of my application.
My progress bar location is 0,430
Progress bar dimensions are 600,11
Can anyone please help me?
using (var sf = new StringFormat()
{
Alignment = StringAlignment.Center,
LineAlignment = StringAlignment.Center,
})
{
progressBar1.CreateGraphics()
.DrawString(message,
new Font("Arial",
(float) 20, FontStyle.Regular),
Brushes.Black,
new Rectangle(0, 0, 600, 480), sf);
}
Use this to measure the size of the string: Graphics.MeasureString
Then use this simple formula:
containerWidth // width in pixels of the container
textWidth // width of your string in pixels
margin = (containerWidth - textWidth) / 2;
You must offset the text from the left by margin pixels.
