Info about FeatureLayer ( Selection on feature layer )

MarcoRosa

Hi to all,
just one information .... referring on sample:

http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#FeatureLayerSelection

So, to do multiple selection is necessary to press keyboard button ..... it's possible to set this option by default and make directly multiple selection instead of press keyboard button each time ?
Better without the botton .... 🙂

Button code section is that:

               <Button x:Name="EnableKeyboardButton" Margin="2"
                            Content="Keyboard"
                            Command="{Binding Select}"
                            CommandParameter="Keyboard"
                            >
                    </Button>


many and many thaks ....

If I understood your question correctly, you want to be able to add to/remove from selection without clicking on any button and only using your keyboard and mouse.

If that is the case, you can listen to KeyDown and pass the proper command parameter on the editor's Select command based on the pressed key.

 
        public MainPage()
        {
            InitializeComponent();
            this.KeyDown += new KeyEventHandler(MainPage_KeyDown);
            editor = this.LayoutRoot.Resources["MyEditor"] as Editor;
        }
        Editor editor;
        void MainPage_KeyDown(object sender, KeyEventArgs e)
        {
            if (editor == null) return;
            if (e.Key == Key.Ctrl)
                editor.Select.Execute("Add");
            else if (e.Key == Key.Shift)
                editor.Select.Execute("Remove");
            else if (e.Key == Key.Escape)            
                editor.CancelActive.Execute(null);
        }
