Hope this helps.

Based on your information, I made a minor modification to SimpleWebDesktop.aspx (available in WebDesktop sample file). The details are:

• Set Height of WebDesktopManager to 600px.
• Set Width of WebDesktopManager to 800px.

The list below shows the step-by-step in order to reproduce the reported problem in my local end.

1. Save the above changes.
2. View the modified sample page in Chrome and/or Firefox browser.
3. Drag a window until mouse pointer leaves the WebDesktopManager canvas.
4. Drop or release the mouse down button.
5. Move the mouse pointer to enter the WebDesktopManager canvas again.

However, I was unable to replicate the reported problem in my local end by using this sample. For your information, I'm using WebDesktop 4.0.7200.14 and WebUI.NET Framework 3.0.5000.913.

Should you find anything that I might miss during my attempt to reproduce the problem, please feel free to let me know.

There is no two way binding of the CameraSettings on iOS maybe on Android, too. Moving around the map does not update the CameraSettings (I added two way binding in the binding provider). How can I save and restore the state of the map when leaving the map view and navigate back to the map view (view is initialized new)? A sample for iOS and Android would be nice.

The map view is used to show map so it only receives one way binding. Currently it is not possible to save and restore the state of the map when leaving and navigate back.

I found an interesting article in stackoverflow, which discuss about how to restoring Android map state.

Hope this help.

Reason: add snippet code to save and restore map state.

Android

You can try to get the Southwest and Northeast visible region before leaving the map view. Example: add following snippet code in map fragment.

protected override void OnViewDisposed()
{
    LatLng SouthwestBound = this.MapView.Map.Projection.VisibleRegion.LatLngBounds.Southwest;
    LatLng NortheashBound = this.MapView.Map.Projection.VisibleRegion.LatLngBounds.Northeast;

    // place code to save SouthwestBound and NortheastBound in here

    base.OnViewDisposed();
}

Next, set the CameraSettings and apply the latitude and longitude of SouthwestBound and NortheastBound when navigate back at the constructor of the view model.

Example:

public CustomMarkerViewModel()
{
    this.Title = "Custom Marker";
    this.Markers = this.Repository.GetAll();

    this.CameraSettings = new CameraSettings(
        new MapRectBounds(
            new LocationCoordinate(SouthwestBound.Latitude, SouthwestBound.Longitude),
            new LocationCoordinate(NortheastBound.Latitude, NortheastBound.Longitude)));
}

iOS

The Span and Center of map region can be obtained before leave the map view.

protected override void OnViewDisposed()
{
    MKCoordinateSpan SpanPosition = this.Map.Region.Span;
    CLLocationCoordinate2D CenterPosition = this.Map.Region.Center;

    // place code to save SpanPosition and CenterPosition in here
            
    base.OnViewDisposed();
}

Next, set CameraSettings in view model when navigate back to map view.

public CustomMarkerViewModel()
{
    this.Title = "Custom Marker";
    this.Markers = this.Repository.GetAll();

    this.CameraSettings =
        new CameraSettings(new MapRectBounds(new LocationCoordinate(latitude, longitude), radius));
}

Hope this helps.

Glad to hear that the snippet code helps.
