ClearAutomationEventsHelper.IsEnabled Property

Gets or sets whether the ClearAutomationEventsHelper should block automation events to improve application performance. This is a dependency property.

Namespace: DevExpress.Xpf.Core

Assembly: DevExpress.Xpf.Core.v25.1.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

C#

public static bool IsEnabled { get; set; }

VB.NET

Public Shared Property IsEnabled As Boolean

Property Value

Type	Description
Boolean	true to block automation events and improve application performance; otherwise false.

Remarks

DevExpress controls remove UI Automation peers and events to improve performance when UI Automation is not needed. However, they keep them if Narrator is running or the Screen Reader parameter is enabled.

The IsEnabled property is set to false automatically in the following cases:

• Screen reader is active
• Narrator is active
• UITestingEnabled is true

If you need to use the UI Automation framework without screen readers, set the IsEnabled property to false in the application constructor or any other code that is invoked before DevExpress controls are loaded:

C#

public App() {  
    DevExpress.Xpf.Core.ClearAutomationEventsHelper.IsEnabled = false;  
}  

Visual Basic

Partial Public Class App  
    Inherits Application  
    Public Sub New()  
    DevExpress.Xpf.Core.ClearAutomationEventsHelper.IsEnabled = False  
    End Sub
