'Declaration Public Property ColumnSizing As TimelineViewColumnSizing
public TimelineViewColumnSizing ColumnSizing {get; set;}
The UltraTimelineView control can be configured to display various different time intervals nested within one another, but only the columns whose headers reside in the bottom row provide resizing capability. The ColumnSizing property determines whether the width of these columns can be changed via the user interface, and whether the user can initiate this change from the headers, time slot borders, or both.
