WindowShownEventArgs Class

Contains data for the Shown event.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

#Declaration

C#
public class WindowShownEventArgs :
    EventArgs

#Remarks

The Shown event fires after the Window is displayed in one of the following ways:

Handle the Shown event to process show actions. You can also handle the Showing event that fires before the Window is displayed and allows you to cancel this action.

The following example displays the window only after users enable the checkbox:

Razor
<div>
    <DxCheckBox @bind-Checked="@Checked">
        Allow Window
    </DxCheckBox>
    @*...*@
    <DxButton RenderStyle="ButtonRenderStyle.Secondary"
          Click="OnShowAtPositionClick">SHOW A WINDOW</DxButton>
</div>

<DxWindow 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."
          Width="max(25vw, 250px)"
          @ref=WindowRef
          Showing="WindowShowing"
          Shown="WindowShown">
</DxWindow>

@code {
    DxWindow WindowRef;
    bool Checked { get; set; }
    bool WindowVisible { get; set; }

    void WindowShowing(WindowShowingEventArgs args) {
        args.Cancel = !Checked;
    }

    void WindowShown(WindowShownEventArgs args) {
        Checked = false;
    }

    async Task OnShowAtPositionClick(MouseEventArgs args) {
        await WindowRef.ShowAtAsync(args.ClientX, args.ClientY);
    }
}
