DayViewBase.TimeRulerCellStyle Property

Gets or sets the style of the time ruler cells. This is a dependency property.

Namespace: DevExpress.Xpf.Scheduling

Assembly: DevExpress.Xpf.Scheduling.v24.1.dll

NuGet Package: DevExpress.Wpf.Scheduling

Declaration

C#

public Style TimeRulerCellStyle { get; set; }

VB.NET

Public Property TimeRulerCellStyle As Style

Property Value

Type	Description
Style	A Style object that represents a style to be applied to cells within a time ruler.

Remarks

Style objects modify target type instances with the same group of properties, resources, and event handlers.

Target Type: DevExpress.Xpf.Scheduling.Visual.TimeRulerCellControl.

Example

The following example demonstrates how to add multiple time rulers to the scheduler’s Day View using the MVVM architectural pattern.

Use the DayViewBase.TimeRulersSource property to bind the view to a collection of objects containing time ruler settings described in the ViewModel. The DayViewBase.TimeRulerTemplate property specifies a data template based on which time rulers are generated.

Create a custom style for the TimeRulerCellControl to specify format strings for displaying time in the time rulers’ time scale.
