### Q: A window event gives me a window ID. How do I get back the view object I registered?

If you register your own view (for example, a WinForms or WPF window) with `RegisterAppFactoryAsync` or `RegisterInstance`, it becomes an io.Connect window with an ID. Window events, such as focus changes, give you that ID. You often need the opposite: the original view object.

**Find the window**

To find any io.Connect window by ID, use `GetGDWindows()`:

```csharp
var targetWindowId = "29476_0";
IGDWindow[] allWindows = await io.GlueWindows.GetGDWindows();
IGDWindow targetWindow = allWindows.FirstOrDefault(window => window.Descriptor.Id == targetWindowId);

```

To search only your own app’s windows, use `GlueWindows.OwnWindows` ([io.Connect.NET](http://io.Connect.NET) 1.36.0 or later).

**Get the view ([io.Connect.NET](http://io.Connect.NET) 1.37.0 or later)**

From 1.37.0, the library stores the view you passed at registration on the window, under `StickyWindow.View`. Cast it to the type you registered:

```csharp
glue_.GlueWindows.SubscribeEvents<WindowFocusChangedEvent>(((@event, descriptor) =>
{
    if (glue_.GlueWindows.OwnWindows.FirstOrDefault(gdw => gdw.Id == descriptor.Id) is { } wnd)
    {
        var view = wnd.StickyWindow.View as Window;
        Debug.WriteLine($"{(@event.Data ? "got" : "lost")} focus: {@event.WindowId} with host {descriptor.ApplicationName}");
    }
}));

```
