IXafCultureInfoService.CultureChanging Event

Fires before a change of culture in the application.

Namespace: DevExpress.ExpressApp.Blazor.Services

Assembly: DevExpress.ExpressApp.Blazor.v25.1.dll

NuGet Package: DevExpress.ExpressApp.Blazor

Declaration

C#

event EventHandler<CultureChangingEventArgs> CultureChanging

VB.NET

Event CultureChanging As EventHandler(Of CultureChangingEventArgs)

Event Data

The CultureChanging event's data class is DevExpress.ExpressApp.Blazor.Services.CultureChangingEventArgs.

Remarks

XAF raises the CultureChanging event before the application’s culture changes, for example, when a user selects a different language. Use the event to intercept and perform custom actions before the culture switches and the page reloads if you need to validate, cancel, or log the culture change. To cancel the culture change, set the Cancel property of the CultureChangingEventArgs to true to prevent switching the culture and reloading the page.

You can use this event to control when and how the culture is changed and enforce business rules or perform localization-specific logic before the change takes effect. However, it is important to use caution when you cancel the culture change, as it may affect the overall user experience or consistency of the application’s behavior.

For an example of use, see the following code snippet:

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Blazor.Services;

namespace MySolutionName.Blazor.Server.Controllers;

public class MyController : WindowController {
    protected override void OnActivated() {
        base.OnActivated();
        var cultService = Application.ServiceProvider.GetService<IXafCultureInfoService>();
        cultService.CultureChanging += CultService_CultureChanging;
    }

    private void CultService_CultureChanging(object sender, CultureChangingEventArgs e) {
        e.Cancel = true;
    }
}
