There are two ways to control the size of the track bar’s thumb:
Set the AutoSize property to True. In this case, dimensions of the thumb will be calculated automatically with respect to the track bar width (the TrackSize property). Values of the ThumbWidth and ThumbHeight properties will be ignored in this case.
Set the AutoSize property to False and specify the thumb’s dimensions manually using the ThumbHeight and ThumbWidth properties.
Note that you cannot assign values less than 10 to the ThumbHeight property.
