The following sample code illustrates how the resolve the appearance of various parts of the scrollbar by calling methods on the ScrollBarLook object.

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinScrollBar

Private Sub button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles button2.Click

    Dim appData As AppearanceData
    Dim requestedProps As AppearancePropFlags

    Dim sbLook As ScrollBarLook

    sbLook = Me.ultraScrollBar1.ScrollBarInfo.ScrollBarLook

    ' -----------------------------------------------
    ' Resolve the default appearance of the scrollbar
    ' -----------------------------------------------

    ' Initialize the appearance data structure		
    appData = New AppearanceData()

    ' Specify which appearance properties we want to resolve.
    ' In this case just the backcolor and forecolor.
    requestedProps = AppearancePropFlags.BackColor Or AppearancePropFlags.ForeColor

    ' Call the ScrollBarLook's 'ResolveAppearance' method .
    sbLook.ResolveAppearance(appData, requestedProps)

    ' Note: The reason that the 'requestedProps' parameter
    ' is also passed in by reference is that as each requested
    ' property is resolved its bit is stripped out of the
    ' passed in parameter. On return from the call the only
    ' bits remaining in 'requestedProps' will be those 
    ' properties which were not resolved. Normally,
    ' 'requestedProps' has no bits set after the call returns.

    ' Write out the resolved colors
    Debug.WriteLine("BackColor: " + appData.BackColor.ToString() + ", ForeColor: " + appData.ForeColor.ToString())

    ' --------------------------------------------
    ' Resolve the appearance of scroll bar buttons
    ' --------------------------------------------

    ' Re-initialize the appearance data structure 
    appData = New AppearanceData()

    ' Specify which appearance properties we want to resolve.
    ' In this case we want all 'Render' properties. This
    ' includes every property but the 'Cursor' property.
    requestedProps = AppearancePropFlags.AllRender

    ' Call the ScrollBarLook's 'ResolveButtonAppearance' method.
    sbLook.ResolveButtonAppearance(appData, requestedProps)

    ' Write out the resolved gradient related properties.
    Debug.WriteLine("BackGradientStyle: " + appData.BackGradientStyle.ToString() + ", BackColor: " + appData.BackColor.ToString() + ", BackColor2: " + appData.BackColor2.ToString())


    ' There are also methods for resolving the appearance
    ' of the thumb and the track area.
