DXCommonDialog.ShowDefaultDialog Event

Fires when running DevExpress file dialogs in an unsupported OS (e.g. Windows XP).

Namespace: DevExpress.Xpf.Dialogs

Assembly: DevExpress.Xpf.Dialogs.v24.2.dll

NuGet Package: DevExpress.Wpf.Dialogs

Declaration

C#

public event EventHandler<NotSupportedOsVersionEventArgs> ShowDefaultDialog

VB.NET

Public Event ShowDefaultDialog As EventHandler(Of NotSupportedOsVersionEventArgs)

Event Data

The ShowDefaultDialog event's data class is NotSupportedOsVersionEventArgs. The following properties provide information specific to this event:

Property	Description
Dialog	Gets the DevExpress file dialog that cannot be run under Windows versions before Vista.
DialogResult	Returns a result of a fallback dialog, which was launched instead of the DevExpress file dialog.
Handled	Gets or sets whether a file dialog fallback is handled and no default processing is required.

Remarks

The DevExpress file dialogs replace standard WPF dialogs. These DevExpress counterparts fully support themes and can be displayed on Windows Vista and newer. For older OS versions, default WPF dialogs are displayed instead and the ShowDefaultDialog event is raised.
