TimeRulerCellControl Class

Visualizes a cell in the TimeRuler element of the Day View, WorkWeek View, and Week View views.

Namespace: DevExpress.Xpf.Scheduling.Visual

Assembly: DevExpress.Xpf.Scheduling.v19.2.dll

Declaration

C#

public class TimeRulerCellControl :
    ChromeBase

VB.NET

Public Class TimeRulerCellControl
    Inherits ChromeBase

Remarks

To display its content, the TimeRulerCellControl element uses the TimeRulerCellPresenter, TimeRulerCellHourPresenter and the TimeRulerCellMinutePresenter instances.

The TimeRulerCellControl.Content property provides access to a View Model passed to the control.

Tip

To specify formats to display hour and minutes in the time ruler, set the TimeRulerCellControl.HourStringFormat and TimeRulerCellControl.MinuteStringFormat properties.

Tip

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=T610483.

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.
