Editorial Note

This article is an entry in our AppInnovation Contest. Articles in this sub-section are not required to be full articles so care should be taken when voting.


I built this app for App Innovation Contest. My app gets your location coordinates using GPS (in your device) or using IP address. It displays a list of hospitals near your location. It will also provide you Yahoo ratings for the hospitals and plot them on a map. It allows user to search hospitals near any US Zip Code. This app is very useful if you have small children or an elderly person in your house.


The basic idea of this app is to provide you with important information which can be used during emergency. In an emergency situation we don’t have time to do a search on internet for nearby hospitals and find their ratings. This app makes important information available to you at your fingertips.

This app uses following technical components:

  1. Uses MVVM to bind data with controls.
  2. Uses Geolocator class’s GetGeopositionAsync method to obtain user’s location. Here is the code which retrieves user’s current location.
    Geolocator geo = new Geolocator();Geoposition cur_pos;
    cur_pos = await geo.GetGeopositionAsync();
  3. Calls a Web service to obtain list of nearby hospitals based on user’s Location. The results are then mapped to the UI using Data Binding. The results are displayed using ListView control. Here is the sample code:
    <ListView   x:Name="itemGridView"            ItemSource={Binding Results}"
                ItemTemplate="{StatisResource HospitalItemTemplate}"
                ItemClick="itemGridView_ItemClick" />
  4. The app also plots the locations in the resultset on the map. Following code is used to plot an image on the map:
    <bm:Map x:Name="map"
     Image img;
     img = new Image();
     img.Width = 32;
     img.Height = 32;
     img.Opacity = 0.8;
     BitmapImage bi = new BitmapImage();
     bi.UriSource = new Uri("ms-appx:///Assets/your_icon.png");
     Location pos = new Location(cur_pos.Coordinate.Latitude, cur_pos.Coordinate.Longitude);
     img.Source = bi;
     MapLayer.SetPosition(img, pos);
     map.SetView(pos, 12.0f);
  5. When user clicks on any one of the item in the resultset, it would be nice to pan the map so that the selected location shows up in the center of the map. Here is the code for doing that:
     private void  itemGridView_ItemClick(object sender, ItemClickEventArgs e)
            // Get the Result object which stores the resultset.
            Model.Result res = ((Model.Result)e.ClickedItem);
            Location currloc = new Location(double.Parse(res.Latitude,CultureInfo.InvariantCulture),double.Parse(res.Longitude,CultureInfo.InvariantCulture));
            map.SetView(currloc, 15.0f);
  6. This app also makes use of LiveTiles features in Windows 8. It displays a list of nearby hospitals in a WideTile format to the user when the application is not running.
  7. This app provides a screen where the user can search nearby Hospitals by entering a Zip Code.
  8. User can either run this app in a Snap, Full Screen or Filled Screen view.

Points of Interest

I learned a lot about Windows 8 Store app when developing this app and how to handle errors within code without impacting the user experience.

Here are some of the App Screenshots:


This is the version 1.0 of my app.
