[Solved] MapMode button crashes in Silverlight 3

[tongyang]

I started a new project, building to .NET 3.5 and Silverlight 3... added RadMap and using BingMapProvider.  This is the xaml file:

<UserControl x:Class="RadControlsSilverlightApp1.MainPage"
        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:telerikRadMap="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.DataVisualization"
        mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480">
    <Grid x:Name="LayoutRoot">
        <telerikRadMap:RadMap Margin="12" Name="radMap1" AllowedCommands="Road,Aerial,Birdseye" />
    </Grid>
</UserControl>

And this is the code behind:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

using Telerik.Windows.Controls;
using Telerik.Windows.Controls.Map;
using Telerik.Windows.Data;

namespace RadControlsSilverlightApp1
{
    public partial class MainPage : UserControl
    {
        public MainPage()
        {
            InitializeComponent();
            BingMapProvider provider = new BingMapProvider(MapMode.Aerial, true, "key");
            this.radMap1.Provider = provider;
        }
    }
}

With the key being the real BingMaps key.  Running this, whenever I hover the MapMode button in the CommandBar, the whole silverlight app just crashes with the message:

Silverlight application code 4004
Message: System.Windows.Markup.XamlParseException: AG_E_PARSER_BAD_PROPERTY_VALUE [Line:13 Position: 30]

Any ideas?  Thanks in advance.

Hi tongyang,

As of Q3 2010 official release we have discontinued the support of our RadControls suite for Silverlight 3. We have been supporting our Silverlight 3 controls more than six months after the official release of RadControls for Silverlight 4 to ensure smooth transition between these two versions.

The default UI of the the RadMap control uses features which are not available in Silverlight 3 so you will not be able to use the control in Silverlight 3 project -- as you are starting new project, we would suggest you to target the Silverlight 4 framework and the control will work as expected.

Thank you for your reply.  Unfortunately the network where our users are going to be, is not approved for silverlight 4 yet, so going to 4 is not an option for us.

Hello tongyang,

In this case you will need to use the latest official Silverlight 3 binaries we have released with Q2 2010 SP2 (version 2010.2 924.1030). You can download them from this link (note that you need to be logged-in in your Client.Net account).


Best wishes,
