ColumnAutoSizing Property

Returns or sets a value indicating whether the value of the ColumnWidth property is set to the ideal width for the PrimaryInterval when the user double-clicks the adjustable area of the header.
Syntax
'Declaration
 
Public Property ColumnAutoSizing As TimelineViewColumnAutoSizing
public TimelineViewColumnAutoSizing ColumnAutoSizing {get; set;}
Remarks

Note: The ColumnAutoSizing property is not applicable when the ColumnSizing property is set to 'None' or 'Column'; header sizing must be enabled in order for the user to be able to auto-size the columns.

Example
The following code sample demonstrates how to use the properties of the UltraTimelineView control to customize the column headers.

Imports System.Collections.Generic
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinSchedule
Imports System.Diagnostics

    Public Sub InitColumnProps(ByVal control As UltraTimelineView)

        '  Set ColumnAutoSizing to 'AllVisibleIntervals' so that when the user auto-sizes
        '  the columns, the width required to show the additional interval's captions is considered
        control.ColumnAutoSizing = TimelineViewColumnAutoSizing.AllVisibleIntervals

        '  Use the ColumnHeaderAppearance to customize the look for all headers
        control.ColumnHeaderAppearance.BackColor = Color.White
        control.ColumnHeaderAppearance.BackColor2 = Color.LightBlue
        control.ColumnHeaderAppearance.BorderColor = Color.DarkBlue
        control.ColumnHeaderAppearance.ForeColor = Color.DarkBlue

        '  Don't show images on the headers
        control.ColumnHeaderImageVisible = False

        '  Only display the minutes for the primary interval, if there is
        '  an additional interval being displayed for the hours.
