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

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

Remarks

Handle the Shown event to process show actions. This event occurs in the following cases:

• You set the IsOpen property to true.
• You call the ShowAsync method.

You can handle the Showing event that fires before the flyout window is displayed and allows you to cancel this action. To process close actions, handle the Closing and Closed events.

The following example allows users to display the flyout window only after they enable the checkbox:

<div>
    <DxCheckBox @bind-Checked="@Checked">Allow flyout Window</DxCheckBox>
    <DxButton Id="button" Text="Show" Click="() => IsOpen = true" />
</div>

<DxFlyout @bind-IsOpen="@IsOpen"
            HeaderText="Header"
            BodyText="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris sit amet metus vel
             nisi blandit tincidunt vel efficitur purus."
            Width="400"
            PositionTarget="#button" Position="FlyoutPosition.LeftStart"
            Showing="WindowShowing"
            Shown="WindowShown">
</DxFlyout>
@code {
    bool Checked { get; set; }
    bool IsOpen { get; set; }

    void WindowShowing(FlyoutShowingEventArgs args) {
        args.Cancel = !Checked;
    }
    void WindowShown(FlyoutShownEventArgs args) {
        Checked = false;
    }
}
