Initialize Method (UltraScrollBar)

Initializes the properties of the Infragistics.Win.UltraWinScrollBar.ScrollBarInfo with the specified values.
Syntax
'Declaration
 
Public Sub Initialize( _
   ByVal minimum As Integer, _
   ByVal maximumDragValue As Integer, _
   ByVal smallChange As Integer, _
   ByVal largeChange As Integer _
) 
public void Initialize( 
   int minimum,
   int maximumDragValue,
   int smallChange,
   int largeChange
)

Parameters

minimum
Minimum value the user can drag to.
maximumDragValue
Maximum value the user can drag to.
smallChange
How much the control scrolls when using the scroll arrows.
largeChange
How much the control scrolls when clicking in the scroll track.
Remarks

Since the actual maximum value that can be achieved by using the interface may be less than the Maximum property, this method provides a way to specify the actual maximum value that the user should be able to get to.

Example
The following sample code illustrates how to set various properties exposes by the UltraScrollBar control.

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinScrollBar

Private Sub InitializeScrollBar()

    With Me.ultraScrollBar1

        ' Note: Under Windows XP if the 'SupportThemes' property
        ' is left set to True (its default setting) then some of

        ' to use a gradient.
        .Appearance.BackColor = Color.LightGray
