Hello,
I have a problem with the RadMap component which leads the silverlight plugin to a crash.
Basically i'm changing periodically the center of the map using the "ZoomLevel" and the "Center" properties of the map and after a casual number of times the silverlight plugin crashes with an "AccessViolationException"
In order to reproduce the issue is sufficient to create a project with a simple user control with the following XAML:
<UserControl x:Class="RadMapTest.Map"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="400">
<Grid x:Name="LayoutRoot" Background="White">
<telerik:RadMap x:Name="MapControl" >
<telerik:RadMap.Provider>
<telerik:ArcGisMapProvider Mode="Aerial" />
</telerik:RadMap.Provider>
</telerik:RadMap>
</Grid>
</UserControl>
And the following code behind:
using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Threading;
namespace RadMapTest
{
public partial class Map : UserControl
{
private bool zoomOut;
private DispatcherTimer timer;
private Random random;
public Map()
{
this.zoomOut = true;
this.timer = new DispatcherTimer();
this.random = new Random(DateTime.Now.Second);
InitializeComponent();
this.Loaded += OnLoaded;
}
private void OnLoaded(object sender, RoutedEventArgs e)
{
this.timer.Interval = TimeSpan.FromMilliseconds(1000);
this.timer.Tick += this.OnTick;
this.timer.Start();
}
private void OnTick(object sender, EventArgs e)
{
this.MapControl.Center = new Telerik.Windows.Controls.Map.Location((random.NextDouble() * 180) - 90, (random.NextDouble() * 360) - 180);
this.MapControl.ZoomLevel = zoomOut ? this.MapControl.MinZoomLevel : random.Next(this.MapControl.MinZoomLevel, this.MapControl.MaxZoomLevel);
zoomOut = !zoomOut;
}
}
}
I was able to reproduce this issue with the Silverlight Q1 2014 and Silverlight Q2 2014.
Also I have tried both Bing and ArcGIS providers.
In the test i'm using a very short animation time (1 sec), but the problems persists also with longer timings (e.g. 45 sec).
Can you provide some help on this?
