CustomizeElementStyleEventArgs.IsAlternate Property

Gets a value that indicates whether an element is highlighted within the scheduler control.

Namespace: DevExpress.Web.ASPxScheduler

Assembly: DevExpress.Web.ASPxScheduler.v19.2.dll

Declaration

C#

public bool IsAlternate { get; }

VB.NET

Public ReadOnly Property IsAlternate As Boolean

Property Value

Type	Description
Boolean	true if the visual element is highlighted; otherwise, false.

Remarks

If the IsAlternate property is set to true, a visual element can have a specific appearance. For example, a date header and date cell corresponding to today’s date can be highlighted within the scheduler control.

Example

This example demonstrates how to set a specific font color for a date header corresponding to today’s date. To do this, handle the ASPxScheduler.CustomizeElementStyle event. Use the CustomizeElementStyleEventArgs.ElementType property to obtain whether the processed element is a date header and the CustomizeElementStyleEventArgs.IsAlternate property to determine whether the date header shows today’s date.

Assign the required font color to the corresponding property of the Style object returned by the CustomizeElementStyleEventArgs.Style property.

C#

using DevExpress.Web.ASPxScheduler;
using System.Drawing;
// ...

protected void ASPxScheduler1_CustomizeElementStyle(object sender, CustomizeElementStyleEventArgs e) {
    if (e.ElementType == WebElementType.DateHeader && e.IsAlternate == true) {
        e.Style.ForeColor = Color.Coral;
    }
}

VB.NET

Imports DevExpress.Web.ASPxScheduler
Imports System.Drawing
' ...

Protected Sub ASPxScheduler1_CustomizeElementStyle(ByVal sender As Object, _
                                                   ByVal e As CustomizeElementStyleEventArgs)
    If e.ElementType = WebElementType.DateHeader AndAlso e.IsAlternate = True Then
        e.Style.ForeColor = Color.Coral
    End If
End Sub
