Click on map - SDK - WPF

[NicolasBiboba]

Hello,

I have a very basic problem which I hope you will be able to solve.
I created a new task in arcGIS mobile 10.1.1 and I want to display a map on part of the screen and on the other part texboxes showing the coordinates of the points clicked on the map.

The problem is that I can't create a mouse event on the map : I have an unknown error and the log file does not help me. I have no idea how to skirt the problem. Maybe this is not the proper way to do it.But I precise that the method that manage the event does do the job and shows the coordinates and the error comes after. Here is the main lines of the code

                private Coordinate destination;
                private MobileCache m_mobileCache;

                // Create an instance of MobileCache, and set StoragePath
                m_mobileCache = new MobileCache();    
                m_mobileCache.StoragePath = @"mypath";
                m_mobileCache.Open();

                //Load layers from MobileCache to Mapcontrol 
                myMap.MapLayers.Add(m_mobileCache);
                
                myMap.CurrentNavigationMode = ESRI.ArcGIS.Mobile.WPF.NavigationMode.Pan;


            myMap.MouseLeftButtonDown += new MouseButtonEventHandler(myMap_MouseLeftButtonDown);

        void myMap_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            System.Windows.Point pt = e.GetPosition(myMap);
            int x = (int)pt.X;
            int y = (int)pt.Y;
            destination = myMap.ToMap(x, y);
            txtLongitude.Text = System.Convert.ToString(x);
            txtLatitude.Text = System.Convert.ToString(y);
        }

And the log file :
Stack Trace:
