TabControl.DisplayRectangle Property

Gets the display area of the control's tab pages.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public override Rectangle DisplayRectangle { get; }

Property Value

Type: System.Drawing.Rectangle
A Rectangle that represents the display area of the tab pages.

The following code example creates a TabControl with one TabPage. This example uses the DisplayRectangle property to draw a Rectangle representing the tab page display area of tabControl1. Notice that the example uses the Inflate method; otherwise, the TabPage drawing code overwrites the Rectangle drawn in the DrawOnTabPage method.

Use the System.Drawing and System.Windows.Forms namespaces for this example.

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

public class Form1 : Form
    private Rectangle myTabRect;

    public Form1()
        TabControl tabControl1 = new TabControl();
        TabPage tabPage1 = new TabPage();

        tabControl1.DrawMode = TabDrawMode.OwnerDrawFixed;
        tabControl1.Appearance = TabAppearance.Buttons;
        tabControl1.Location = new Point(25, 25);

        // Gets a Rectangle that represents the tab page display area of tabControl1.
        myTabRect = tabControl1.DisplayRectangle;

        myTabRect.Inflate(1, 1); 
        tabControl1.DrawItem += new DrawItemEventHandler(DrawOnTabPage);

    private void DrawOnTabPage(object sender, DrawItemEventArgs e)
        Graphics g = e.Graphics;
        Pen p = new Pen(Color.Blue);
        g.DrawRectangle(p, myTabRect);

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