DxWindow.Closed Event

Fires after the Window is closed.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[Parameter]
public EventCallback<WindowClosedEventArgs> Closed { get; set; }

Event Data

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

Property	Description
CancellationToken	Specifies an object that propagates a cancellation notification.

Remarks

Handle the Closed event to process close actions. This event occurs in the following cases:

• A user closes the Window: clicks the Close button, clicks outside the Window boundaries, or presses Escape.
• You set the Visible property to false.
• You call the CloseAsync method.
• The Window is closed in a custom way (the CloseCallback is called from any template).

You can also handle the Closing event that fires before the Window is closed and allows you to cancel this action. To process show actions, handle the Showing and Shown events.

In the following example, neither the Close button in the header nor the custom OK button closes the Window until a user enables the checkbox in the footer:

<DxButton Id="showDDbtton" Click="() => IsOpen = true">SHOW A WINDOW</DxButton>
<DxWindow Width="400"
            @bind-IsOpen="@IsOpen"
            ShowFooter="true"
            HeaderText="DevExpress EULA"
            Closing="EulaClosing"
            Closed="EulaClosed">
    <BodyTextTemplate>

        <DxButton RenderStyle="ButtonRenderStyle.Primary" Text="OK" Click="context.CloseCallback" />
    </FooterTextTemplate>
</DxWindow>

@code {
    bool IsOpen { get; set; } = false;
    bool EulaAccepted { get; set; }

    void EulaClosing(WindowClosingEventArgs args) {
        if (args.CloseReason == WindowCloseReason.Programmatically) {
            args.Cancel = !EulaAccepted;
        }
    }
    void EulaClosed(WindowClosedEventArgs args) {
        EulaAccepted = false;
    }
