ya its working... thanks

You can get notified of the map scale changing by using the WindowRectChanged event. And you can examine the current map zoom level by examining the property WindowZoom. e.g.

private void theMap_WindowRectChanged(object sender,
            Infragistics.Silverlight.Map.MapWindowRectChangedEventArgs e)
        {
            System.Diagnostics.Debug.WriteLine(theMap.WindowZoom.ToString());
        }

This help?

hi

  how to get the zoom  level when im zooming in or out. Because i want to display some controls or images over map when i am in particular zoom level. Let say i want to display chart at zoom level 3 and i want to display grid at zoom level five.

Hi David

          I am using Geo Spatial data to load map not shape files. I have created service for this. for single layer its working fine. but when i go for more than one layer i.e added dynamically its not working can you please check. My code looks like this

public partial class MainPage : UserControl

    {

        SqlDbServiceReference.SqlDbServiceClient sqlClient;

        string connectionString;

        string layerName = "Layer1";

        DataMapping.Converter convertor;

        public MainPage()

        {

            InitializeComponent();

            sqlClient = new DEMO_N.SqlDbServiceReference.SqlDbServiceClient();

            connectionString = "Integrated Security=True;Initial Catalog=sampledata;Data Source=IE11DT485ZL1S";

            convertor = new DataMapping.Converter();

        }

           private void myMap_Loaded(object sender, RoutedEventArgs e)

        {

 sqlClient.GetDataCompleted +=new EventHandler<DEMO_N.SqlDbServiceReference.GetDataCompletedEventArgs>(sqlClient_GetDataCompleted);

            sqlClient.GetDataAsync(connectionString, "select * from Plantlevel1");

            MessageBox.Show("1");

                for (int i = 0; i < 1; i++)

              {

                   MapLayer newLayer = new MapLayer();

                   newLayer.VisibleFromScale = i + 1;

                   newLayer.LayerName = "Layer" + (i + 2);               

                   newLayer.Reader = new SqlShapeReader();

                   newLayer.DataMapping = (DataMapping)convertor.ConvertFromString("Data=geom;Name=ID");

                   myMap.Layers.Add(newLayer);

                   layerName = "Layer2";

                   SqlDbServiceReference.SqlDbServiceClient newClient1 = new DEMO_N.SqlDbServiceReference.SqlDbServiceClient();

                   sqlClient.GetDataAsync(connectionString, "select * from plantlevel2");

               }

        }

 public void sqlClient_GetDataCompleted(object sender, SqlDbServiceReference.GetDataCompletedEventArgs e)

        {

            SqlShapeReader sqlReader = myMap.Layers[layerName].Reader as SqlShapeReader;

            if (sqlReader != null)

            {

               sqlReader.DataSource = e.Result;

                myMap.Layers[layerName].ImportAsync();

            }

        }

    }
