By default, you can hold "Shift" key and then draw a rectangle on the MapView to use similar navigation. If you want to zoom out, you can do "Shift+ Ctrl" combo instead. If you want to implement your own, then you can do something like this: private async void Button_Click(object sender, RoutedEventArgs e) { try { // use the MapView's Editor to request geometry (Envelope) from the user and await the result var newExtent = await myMapView.SketchEditor.StartAsync(Esri.ArcGISRuntime.UI.SketchCreationMode.Rectangle, false); // set the map view extent with the Envelope await myMapView.SetViewpointGeometryAsync(newExtent); } catch (TaskCanceledException tce) { // sketching cancelled } catch (Exception ex) { } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
