Example
The following code sample demonstrates how to use the KeyActionMappings collection to customize keyboard behavior for the UltraTimelineView control:

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

    Public Sub EnableHorizontalPaging(ByVal control As UltraTimelineView)

        Next

        For Each mapping As UltraTimelineViewKeyActionMapping In forRemoval
            keyMappings.Remove(mapping)
        Next
