Public ReadOnly Property OldFirstVisibleResourceIndex As Integer

Property Value

Type	Description
Int32	An integer that is the index of a resource in the SchedulerViewInfoBase.VisibleResources collection.

Remarks

The collection of visible resources is accessible using the SchedulerViewInfoBase.VisibleResources property. To hide certain resources, that is, to remove them from the collection of visible resources, handle the SchedulerStorageBase.FilterResource event.

The OldFirstVisibleResourceIndex gets the collection index of a resource which is actually displayed in the current SchedulerControl.ActiveView when grouping is applied to the view (use the SchedulerViewBase.GroupType property to apply grouping).
