public ToolStripItemImageScaling ImageScaling { get; set; }

Property Value

Type: System.Windows.Forms.ToolStripItemImageScaling

One of the ToolStripItemImageScaling values. The default is SizeToFit.

The Image, ImageAlign, ImageIndex, ImageKey, and ImageScaling properties pertain to various aspects of image handling. Use images in ToolStrip controls by setting these properties directly or by setting the run-time–only ImageList property.

Image scaling is determined by the interaction of properties in both ToolStrip and ToolStripItem, as follows:

The following code example demonstrates how to set the Image, ImageScaling, and ImageTransparentColor for a ToolStripItem. In addition, it demonstrates how to set and show a custom ToolTip for the item.

internal ToolStripButton imageButton;

private void InitializeImageButtonWithToolTip()

	// Construct the button and set the image-related properties.
	imageButton = new ToolStripButton();
	imageButton.Image = new Bitmap(typeof(Timer), "Timer.bmp");
	imageButton.ImageScaling = ToolStripItemImageScaling.SizeToFit;

	// Set the background color of the image to be transparent.
	imageButton.ImageTransparentColor = Color.FromArgb(0, 255, 0);

	// Show ToolTip text, set custom ToolTip text, and turn
	// off the automatic ToolTips.
	toolStrip1.ShowItemToolTips = true;
	imageButton.ToolTipText = "Click for the current time";
	imageButton.AutoToolTip = false;

	// Add the button to the ToolStrip.
