Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v25.2.dll

NuGet Package: DevExpress.Win.Navigation

[DXCategory("Events")]
public event DisableCalendarDateEventHandler DisableCalendarDate

Public Event DisableCalendarDate As DisableCalendarDateEventHandler

Event Data

The DisableCalendarDate event's data class is DevExpress.XtraEditors.Calendar.DisableCalendarDateEventArgs.

Remarks

Handle the DisableCalendarDate event to prevent users from selecting specific dates or date ranges. The event fires for each day cell in the drop-down calendar before it is rendered. Set the e.Disabled event parameter to true to disable the processed date.

The following code snippet disables all weekend dates in the drop-down calendar:

C#

using DevExpress.XtraEditors.Controls;

dateEdit1.DisableCalendarDate += (sender, e) => {
    if (e.Date.DayOfWeek == DayOfWeek.Saturday || e.Date.DayOfWeek == DayOfWeek.Sunday)
        e.IsDisabled = true;
};

VB.NET

Imports DevExpress.XtraEditors.Controls

AddHandler dateEdit1.DisableCalendarDate, Sub(sender, e)
    If e.Date.DayOfWeek = DayOfWeek.Saturday OrElse e.Date.DayOfWeek = DayOfWeek.Sunday Then
        e.IsDisabled = True
    End If
End Sub

The DisableCalendarDate event is equivalent to RepositoryItemDateEdit.DisableCalendarDate.
