DxMessageBox.Shown Event

Fires after the message box is displayed.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[Parameter]
public EventCallback Shown { get; set; }

Remarks

Handle the Shown event to perform actions after the message box appears. The following code sample hides the message box 3 seconds after it is displayed:

@using System.Timers;

<DxButton Text="Show Alert" Click="@(() => MessageBoxVisible = true)" />
<DxMessageBox @bind-Visible="MessageBoxVisible" 
              Title="Alert" 
              Text="I'm an alert that hides in 3 seconds" 
              Shown="@Shown" />

@code {
    bool MessageBoxVisible { get; set; } = false;
    static Timer mbTimer;

    void Shown() {
        mbTimer = new Timer(3000);
        mbTimer.Elapsed += OnTimedEvent;
        mbTimer.Enabled = true;
    }

    void OnTimedEvent(Object source, ElapsedEventArgs e) {
        MessageBoxVisible = false;
        mbTimer.Stop();
        mbTimer.Dispose();
        InvokeAsync(StateHasChanged);
    }
}
