Imports Infragistics.Win
	
Private Sub SetupGridImages()

    Dim appearance As Appearance = New Appearance()

    appearance.ImageBackground = Me.Icon.ToBitmap()
    appearance.ImageBackgroundOrigin = ImageBackgroundOrigin.Form
    appearance.ImageBackgroundStyle = ImageBackgroundStyle.Stretched
    appearance.ImageBackgroundAlpha = Alpha.UseAlphaLevel
    appearance.AlphaLevel = 125
    appearance.Image = Me.Icon.ToBitmap()
    appearance.ImageVAlign = VAlign.Middle
    appearance.ImageHAlign = HAlign.Center

    Me.ultraGrid1.DisplayLayout.Appearance = appearance

End Sub

C#

using Infragistics.Win;

private void SetupGridImages()
{

	Appearance appearance = new Appearance();

	appearance.ImageBackground = this.Icon.ToBitmap();
	appearance.ImageBackgroundOrigin = ImageBackgroundOrigin.Form;
	appearance.ImageBackgroundStyle = ImageBackgroundStyle.Stretched ;
	appearance.ImageBackgroundAlpha = Alpha.UseAlphaLevel ;
	appearance.AlphaLevel = 125;
