    I have a radmap and i have small pinpoints which on clicking shows up a detailed pint point.
    The detailed pin point when open has the other neighbouring smaller pin points over lapping this and hiding the details.
    I have attached a screenshot which shows the scenario.

    Please help me with an example.Very critical.

    Hello Priya,

    You can use the Canvas.ZIndex property to display the item on the top of the other points. This property should be assigned to the ContentPresenter instance which is used as a cover for the control on the information layer. You can get it using the GetVisualParent extension. The sample code is below.
    using System;
    using System.Collections.ObjectModel;
    using System.Windows;
    using System.Windows.Controls;
    using System.Windows.Input;
    using Telerik.Windows.Controls;
    using Telerik.Windows.Controls.Map;
    namespace ExpandedPinPoints
        public partial class MainPage : UserControl
            private int zIndex = 0;
            public MainPage()
                this.radMap.InitializeCompleted += new EventHandler(radMap_InitializeCompleted);
            private void radMap_InitializeCompleted(object sender, EventArgs e)
                var collection = new Collection<DataPoint>();
                collection.Add(new DataPoint()
                    Location = new Location(40, -100),
                    Title="POI 1",
                    Description="Can be here."
                collection.Add(new DataPoint()
                    Location = new Location(40.2, -100),
                    Title = "POI 2",
                    Description = "Can be here 2."
                this.informationLayer.ItemsSource = collection;
            private void ParentRoot_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
                var templateRoot = sender as FrameworkElement;
                if (templateRoot != null)
                    var small = templateRoot.FindName("small") as FrameworkElement;
                    var big = templateRoot.FindName("big") as FrameworkElement;
                    if (small != null && big != null)
                        var presenter = templateRoot.GetVisualParent<ContentPresenter>();
                        if (small.Visibility == System.Windows.Visibility.Visible)
                            Canvas.SetZIndex(presenter, ++zIndex);
                            small.Visibility = System.Windows.Visibility.Collapsed;
                            big.Visibility = System.Windows.Visibility.Visible;
                            Canvas.SetZIndex(presenter, 0);
                            small.Visibility = System.Windows.Visibility.Visible;
                            big.Visibility = System.Windows.Visibility.Collapsed;
                    e.Handled = true;
