Question

How do I implement a tab control with vertical tabs in C#?

Answer 1

Create an instance of System.Windows.Forms.TabControl (one of the standard container controls for Windows Forms) and set the Alignment property to Left.

Answer 2

First set in properties the Alignment property to Left.

Second set SizeMode property to Fixe.

Third set ItemSize property to prefered size example width :30 height :120.

After that you need to set the DrawMode property to OwnerDrawFixed. Next step is define a handler for the DrawItem event of TabControl that renders the text from left to right.

Example In form Designers.cs file

TabControl.DrawItem += new DrawItemEventHandler(tabControl_DrawItem);

Definition for tabControl_DrawItem method:

private void tabControl_DrawItem(Object sender, System.Windows.Forms.DrawItemEventArgs e)
    {
        Graphics g = e.Graphics;
        Brush _textBrush;

        // Get the item from the collection.
        TabPage _tabPage = TabControl.TabPages[e.Index];

        // Get the real bounds for the tab rectangle.
        Rectangle _tabBounds = TabControl.GetTabRect(e.Index);

        _textBrush = new System.Drawing.SolidBrush(Color.Black);

        // Use our own font.
        Font _tabFont = new Font("Arial", (float)12.0, 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));
    }

Effect:Ready horizontal tabcontrol
