Hi,
I have DynamicLayer and ItemsRequest method which returns collection of MapPinPoint. I would like to handle MouseLeftButtonDown event on MapPinPoint which has to show some information on RadMap. What should I do to achieve that?
I was trying to programmatically add handler for each created MapPinPoint in ItemsRequest method but then I could not access RadMap instance in handler which is in that class (class based on IMapDynamicSource which implements ItemsRequest).

Hello drLich,
When you create the instance of the class which implements the IMapDynamicSource interface then you can reference the instance of class which has access to the RadMap. So, you will have access to the RadMap instance in your handler of mouse event.
Also as an another way you can assign the mouse event handler from the instance of class which has access to the RadMap.

public partial class MainPage : UserControl { public MainPage() { InitializeComponent();
this.dynamicLayer.ZoomGridList.Add(new ZoomGrid(2, 2, 3)); this.dynamicLayer.ZoomGridList.Add(new ZoomGrid(36, 72, 9));
// set dynamic source this.dynamicLayer.DynamicSource = new DynamicSource(this); } private class DynamicSource : IMapDynamicSource { private MainPage page;
public DynamicSource(MainPage page) { this.page = page; }
public void ItemsRequest(object sender, ItemsRequestEventArgs e) { // ... pinPoint.MouseLeftButtonDown += new MouseButtonEventHandler(pinPoint_MouseLeftButtonDown); }
private void pinPoint_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { RadMap map = this.page.RadMap1; } } } Also as an another way you can assign the mouse event handler from the instance of class which has access to the RadMap.
