Value Property (MidpointSettings)

Gets or sets the value that should be represented at the midpoint of the TrackBar.
Syntax
'Declaration
 
Public Property Value As Nullable(Of Integer)
public Nullable<int> Value {get; set;}
Remarks

Note: Setting this property to a value that is not the midpoint of the range of the TrackBar will cause there to be a different number of values on either half of the track; this will take effect even if the midpoint tickmark is not visible.

Example
Imports Infragistics.Win.UltraWinEditors

        ' This method sets up the scale trackbar in a similar way to the Microsoft Office2007
        ' scaling trackbar. We want this trackbar to essentially have 2 different ranges. The first 
        ' range is from 10 to 100 percent. The second range is from 100 to 500 percent.

        ' to represent 100. So we can use the MidPointSettings.Value to set the middle to 100.
