The Shown event's data class is PopupShownEventArgs. 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 can also handle the Showing event that fires before the Popup 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 show the Popup only after they enable the checkbox:

<div>
    <DxCheckBox @bind-Checked="@Checked">
        Allow Popup
    </DxCheckBox>
    @*...*@
    <DxButton RenderStyle="ButtonRenderStyle.Primary" Text="Show"
              Click="() => PopupVisible = true"/>
</div>

<DxPopup @bind-Visible="@PopupVisible"
         HeaderText="Header"
         BodyText="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris sit amet metus vel
             nisi blandit tincidunt vel efficitur purus. Nunc nec turpis tempus, accumsan orci auctor,
             imperdiet mauris. Fusce id purus magna."
         Showing="PopupShowing"
         Shown="PopupShown">
</DxPopup>
@code {
    bool Checked { get; set; }
    bool PopupVisible { get; set; }

    void PopupShowing(PopupShowingEventArgs args) {
        args.Cancel = !Checked;
    }

    void PopupShown(PopupShownEventArgs args) {
        Checked = false;
    }
}
