Hi, i'm trying to write simple application in WPF which can open shp files add it to layers and display them (with possiblity to disable/enable particular layers), but i have big problem with adding layers after boot...

Example 1 (this code don't render file):

        private string filename=null;

        public MainWindow()

        {

            InitializeComponent();

        }

        private void button1_Click(object sender, RoutedEventArgs e)

        {

            // Create OpenFileDialog

            Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();

            // Set filter for file extension and default file extension

            dlg.DefaultExt = ".shp";

            dlg.Filter = "Text documents (.shp)|*.shp";

            // Display OpenFileDialog by calling ShowDialog method

            Nullable<bool> result = dlg.ShowDialog();

            // Get the selected file name and display in a TextBox

            if (result == true)

            {

                filename = Path.GetDirectoryName(dlg.FileName) + "\\" + Path.GetFileNameWithoutExtension(dlg.FileName);

            }

            MapLayer WorldLayer = new MapLayer();

            ShapeFileReader reader = new ShapeFileReader();

            reader.Uri = filename;

            WorldLayer.Reader = reader;

            WorldLayer.ImportAsync();

            xamMap1.Layers.Add(WorldLayer);

            MapNavigationPane navPane = new MapNavigationPane();

            navPane.SetValue(XamDock.EdgeProperty, DockEdge.InsideRight);

            navPane.Margin = new Thickness(10);

            xamMap1.LogicalChildren.Add(navPane);

        }

    }

Example 2 (this code renders file):

        private string filename=null;

        public MainWindow()

        {

            InitializeComponent();

            // Create OpenFileDialog

            Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();

            // Set filter for file extension and default file extension

            dlg.DefaultExt = ".shp";

            dlg.Filter = "Text documents (.shp)|*.shp";

            // Display OpenFileDialog by calling ShowDialog method

            Nullable<bool> result = dlg.ShowDialog();

            // Get the selected file name and display in a TextBox

            if (result == true)

            {

                filename = Path.GetDirectoryName(dlg.FileName) + "\\" + Path.GetFileNameWithoutExtension(dlg.FileName);

            }

            MapLayer WorldLayer = new MapLayer();

            ShapeFileReader reader = new ShapeFileReader();

            reader.Uri = filename;

            WorldLayer.Reader = reader;

            WorldLayer.ImportAsync();

            xamMap1.Layers.Add(WorldLayer);

            MapNavigationPane navPane = new MapNavigationPane();

            navPane.SetValue(XamDock.EdgeProperty, DockEdge.InsideRight);

            navPane.Margin = new Thickness(10);

            xamMap1.LogicalChildren.Add(navPane);

        }

        private void button1_Click(object sender, RoutedEventArgs e)

        {

        }

    }

And here is XAML file in both cases the same:

         <Window x:Class="testwczytywania.MainWindow"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        Title="MainWindow" Height="350" Width="525"

        xmlns:ig="http://schemas.infragistics.com/xaml">

    <Grid>

        <Grid.RowDefinitions>

            <RowDefinition Height="26*" />

            <RowDefinition Height="285*" />

        </Grid.RowDefinitions>

        <Button Content="Button" Height="23" HorizontalAlignment="Left" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />

        <Grid Grid.Row="1">

                <ig:XamMap HorizontalAlignment="Left" Margin="11,37,0,0" Name="xamMap1" VerticalAlignment="Top" MinHeight="299" MinWidth="491" />

        </Grid>

    </Grid>

</Window>
