Size

A Size that represents the size of the tabs. The default automatically sizes the tabs to fit the icons and labels on the tabs.

Examples

The following code example creates a TabControl with two TabPage objects. To define the dimensions of the tabs, set the ItemSize property equal to a Size structure. In this example, Size defines the tabs 90 pixels wide and 50 pixels high. You cannot change the width of the tabs unless the SizeMode property is set to the Fixed value.

C#

using System.Drawing;
using System.Windows.Forms;

public class Form1 : Form
{
    private TabControl tabControl1;
    private TabPage tabPage1;
    private TabPage tabPage2;

    public Form1()
    {
        this.tabControl1 = new TabControl();
        this.tabPage1 = new TabPage();
        this.tabPage2 = new TabPage();
        
        // Sizes the tabs of tabControl1.
        this.tabControl1.ItemSize = new Size(90, 50);

        // Makes the tab width definable. 
        this.tabControl1.SizeMode = TabSizeMode.Fixed;

        this.tabControl1.Controls.AddRange(new Control[] {
            tabPage1, tabPage2});
        this.tabControl1.Location = new Point(35, 25);
        this.tabControl1.Size = new Size(220, 220);

        this.Size = new Size(300, 300);
        this.Controls.Add(tabControl1);
    }

    static void Main() 
    {
        Application.Run(new Form1());
    }
}

Remarks

To change the Width property of the ItemSize property, the SizeMode property must be set to Fixed.
