Task Settings for WinGanttView

This topic demonstrates settings that can be applied to tasks added to the WinGanttView™ control, using the TaskSettings object. These settings enable you to control end users interaction with a specific task or all tasks within the grid and chart sections of the control. You can restrict end users from editing certain task information. Task settings applied to a specific task have precedence over settings applied directly on the control.

The following example code assumes that you have an UltraGanttView control dropped onto the form that displays tasks and task details. For information on adding tasks to WinGanttView, please see the Adding Tasks to WinGanttView topic.

In Visual Basic:

' Disable editing of Duration, Deadline and deletion for all Tasks
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 specifc user interactions  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]
Me.ultraGanttView1.CalendarInfo.Tasks(0).Tasks(1).TaskSettings.AllowDelete = Infragistics.Win.DefaultableBoolean.[True]

In C#:

// Disable editing of Duration, Deadline and deletion for all Tasks
this.ultraGanttView1.TaskSettings.AllowDelete = Infragistics.Win.DefaultableBoolean.False;
this.ultraGanttView1.TaskSettings.AllowEditDuration = Infragistics.Win.DefaultableBoolean.False;
this.ultraGanttView1.TaskSettings.AllowEditDeadline = Infragistics.Win.DefaultableBoolean.False;
// Allow specifc user interactions  for specific Tasks
this.ultraGanttView1.CalendarInfo.Tasks[0].Tasks[0].TaskSettings.AllowEditStartDateTime = Infragistics.Win.DefaultableBoolean.False;
this.ultraGanttView1.CalendarInfo.Tasks[1].Tasks[0].TaskSettings.AllowEditPercentComplete = Infragistics.Win.DefaultableBoolean. False;
this.ultraGanttView1.CalendarInfo.Tasks[0].Tasks[1].TaskSettings.AllowDelete = Infragistics.Win.DefaultableBoolean.True;
