Gets or sets the visible index of the first resourse currently displayed on-screen.

Namespace: DevExpress.XtraScheduler

Assembly: DevExpress.XtraScheduler.v23.2.dll

NuGet Package: DevExpress.Win.Scheduler

Declaration

C#

[Browsable(false)]
public int FirstVisibleResourceIndex { get; set; }

VB.NET

<Browsable(False)>
Public Property FirstVisibleResourceIndex As Integer

Property Value

Type	Description
Int32	An integer value which represents the zero-based index of the first visible resource.

Remarks

Resources are visible to end-users if the SchedulerControl.GroupType property is set to the Resource value.

The maximum number of resources simultaneously displayed on screen depends on the View’s SchedulerViewBase.ResourcesPerPage property value. You can use the FirstVisibleResourceIndex property to scroll the Scheduler View to the specific resource.
