ToolStripItem.AutoSize Property


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Gets or sets a value indicating whether the item is automatically sized.

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

public bool AutoSize { get; set; }

Property Value

Type: System.Boolean

true if the ToolStripItem is automatically sized; otherwise, false. The default value is true.

Set the AutoSize property to true to cause the ToolStripItem to adjust either its height or width, depending on the orientation of the ToolStrip, to ensure that the ToolStripItem uses only the required amount of space.

A ToolStripItem has a minimum size if the AutoSize property is true. Set the AutoSize property to false if you want a ToolStripItem to be smaller than the system-defined minimum size or to have a ToolStripItem size of zero.

The following code example demonstrates how to set the Text, AutoSize, Overflow, and TextDirection properties, and handle the Click event. To run this example, paste the following code into a form that contains a ToolStrip named movingToolStrip and call InitializeMovingToolStrip in the form's constructor or Load event handler.

internal ToolStripButton changeDirectionButton;

private void InitializeMovingToolStrip()
          movingToolStrip = new ToolStrip();

	changeDirectionButton = new ToolStripButton();

	movingToolStrip.AutoSize = true;
	movingToolStrip.RenderMode = ToolStripRenderMode.System;

	changeDirectionButton.TextDirection = ToolStripTextDirection.Vertical270;
	changeDirectionButton.Overflow = ToolStripItemOverflow.Never;
	changeDirectionButton.Text = "Change Alignment";

private void changeDirectionButton_Click(object sender, EventArgs e)

	ToolStripItem item = (ToolStripItem)sender;

	if (item.TextDirection == ToolStripTextDirection.Vertical270 || item.TextDirection == ToolStripTextDirection.Vertical90)
		item.TextDirection = ToolStripTextDirection.Horizontal;
		movingToolStrip.Dock = System.Windows.Forms.DockStyle.Top;
		item.TextDirection = ToolStripTextDirection.Vertical270;
		movingToolStrip.Dock = System.Windows.Forms.DockStyle.Left;
