This sample code illustrates the way by which you can determine whether your end users can edit or delete tasks, using the TaskSettings object.
Imports Infragistics.Win.UltraWinSchedule
Imports Infragistics.Win.UltraWinGanttView
Private Sub TaskSettings_Load(ByVal sender As Object, ByVal e As EventArgs) Handles TaskSettings.Load
' Disable specific editing for all Tasks visible in GanttView control
Me.ultraGanttView1.TaskSettings.AllowDelete = Infragistics.Win.DefaultableBoolean.[False]
Me.ultraGanttView1.TaskSettings.AllowEditDuration = Infragistics.Win.DefaultableBoolean.[False]
Me.ultraGanttView1.TaskSettings.AllowEditDeadline = Infragistics.Win.DefaultableBoolean.[False]
'Allow specific editing for specific Tasks
Me.ultraGanttView1.CalendarInfo.Tasks(0).Tasks(0).TaskSettings.AllowEditStartDateTime = Infragistics.Win.DefaultableBoolean.[False]
Me.ultraGanttView1.CalendarInfo.Tasks(1).Tasks(0).TaskSettings.AllowEditPercentComplete = Infragistics.Win.DefaultableBoolean.[False]
End Sub
