Control.BackgroundImage Property

Gets or sets the background image displayed in the control.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)
public virtual Image BackgroundImage { get; set; }

Property Value

Type: System.Drawing.Image
An Image that represents the image to display in the background of the control.
  • Use the BackgroundImage property to place a graphic image onto a control.

NoteNote

Images with translucent or transparent colors are not supported by Windows Forms controls as background images.

This property is not supported on child controls whose RightToLeftLayout property is true.

Notes to Inheritors

When overriding the BackgroundImage property in a derived class, use the base class's BackgroundImage property to extend the base implementation. Otherwise, you must provide all the implementation. You are not required to override both the get and set accessors of the BackgroundImage property; you can override only one if needed.

The following code example adds a Button to a form and sets some of its common properties. The example anchors the button to the bottom-right corner of the form so it keeps its relative position as the form is resized. Next it sets the BackgroundImage and resizes the button to the same size as the Image. The example then sets the TabStop to true and sets the TabIndex property. Lastly, it adds an event handler to handle the Click event of the button. This example requires that you have an ImageList named imageList1.

// Add a button to a form and set some of its common properties. 
private void AddMyButton()
{
   // Create a button and add it to the form.
   Button button1 = new Button();

   // Anchor the button to the bottom right corner of the form
   button1.Anchor = (AnchorStyles.Bottom | AnchorStyles.Right);

   // Assign a background image.
   button1.BackgroundImage = imageList1.Images[0];

   // Specify the layout style of the background image. Tile is the default.
   button1.BackgroundImageLayout = ImageLayout.Center;

   // Make the button the same size as the image.
   button1.Size = button1.BackgroundImage.Size;

   // Set the button's TabIndex and TabStop properties.
   button1.TabIndex = 1;
   button1.TabStop = true;

   // Add a delegate to handle the Click event.
   button1.Click += new System.EventHandler(this.button1_Click);

   // Add the button to the form. 
   this.Controls.Add(button1);
}
