HorizontalSingleWeekCell.FirstVisible Property

Indicates whether the current cell is the first visible cell in the cell area of the Month view.

Namespace: DevExpress.XtraScheduler.Drawing

Assembly: DevExpress.XtraScheduler.v19.1.dll

Declaration

C#

public bool FirstVisible { get; set; }

VB.NET

Public Property FirstVisible As Boolean

Property Value

Type	Description
Boolean	True if the cell is the first (upper leftmost) cell in the Month view’s time cell area; otherwise, false.

Remarks

If the view is grouped, an upper leftmost cell in each group is considered the first visible cell.

Example

To identify the first visible cell in the Month View, handle the SchedulerControl.CustomDrawTimeCell event and check whether the HorizontalSingleWeekCell.FirstVisible property value is true.

The following code draws text in the Month view’s first visible cell, as illustrated in th picture below.
