RegistryAccessPolicy Class

Allows you to spot, analyze, and prohibit unwanted requests to the system registry.

Namespace: DevExpress.Data.Utils

Assembly: DevExpress.Data.Desktop.v24.2.dll

Declaration

C#

public static class RegistryAccessPolicy

VB.NET

Public Module RegistryAccessPolicy

Remarks

DevExpress UI controls can save, read, and modify configuration settings and options in the system registry. These requests can be initiated in your code or through the internal control engine. The RegistryAccessPolicy allows you to apply global registry access restrictions, or track user/app initiated requests and execute custom actions in response.

Call one of the following methods at application startup to apply a restrictive policy:

• SuppressAllOperations() – Suppresses all requests to the system registry.
• SuppressReadOperations() – Suppresses read requests from the system registry.
• SuppressWriteOperations() – Suppresses requests to write to the system registry.
• ThrowAlways() – Throws an exception when the control accesses the system registry.
• ThrowOnErrors() – Throws an exception if a request to the system registry fails.

The following example suppresses all read/write requests to the system registry:

C#

static void Main() {
    Application.EnableVisualStyles();
    Application.SetCompatibleTextRenderingDefault(false);
    DevExpress.Data.Utils.RegistryAccessPolicy.SuppressAllOperations();
    Application.Run(new Form1());
}

VB.NET

Shared Sub Main()
    Application.EnableVisualStyles()
    Application.SetCompatibleTextRenderingDefault(False)
    DevExpress.Data.Utils.RegistryAccessPolicy.SuppressAllOperations()
    Application.Run(New Form1())
End Sub

Use the AllowOperation method to allow a specific registry operation.

Handle SetValue, QueryValue, EnumerateSubKeyTree, DeleteSubKeyTree events to allow or cancel registry operations based on a specific condition.
