Adding MapControl in xaml results in a "Catastropic failure"


I am creating an universal application using Visual Studio Ultimate 2013 Version 12.0.30501.00 Update 2. I am getting Catastrophic failure on adding Map Control in my xaml like this

<Maps:MapControl Visibility="Collapsed"/>. 

I have added

xmlns:Maps="using:Windows.UI.Xaml.Controls.Maps" 

in the page header and added 'location' capability to application manifest file. Has anyone faced the same issue? You can test his by creating a sample application and add only MapControl. Please help me to resolve this issue.

The problem is observed in normal Windows Phone 8.1 applications also. Am i missing something here?

The problem is observed when i try to run the application in emulator.

The error does not show any other information just 'catastropic failure', nothing else.

May be i will try to re-install Visual Studio. But one more interesting fact is that i could get it working if i am not hiding the map control in the page.

Can you test it by creating a sample application and just making the map control Visibility='Collapsed'?

<Page
    x:Class="TestMaps.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:TestMaps"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:Maps="using:Windows.UI.Xaml.Controls.Maps" 
    mc:Ignorable="d"
    Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">

    <Grid>
        <Maps:MapControl Visibility="Collapsed" />
    </Grid>
</Page>

And the problem is observed in more than one PC.


Solution

  • I've tested your example and indeed there is such a problem also on my Phone.

    As I have checked it is possible to set Collapsed from code - so as a workaround:

    <Grid>
       <Maps:MapControl Name="myMap" Visibility="Visible" />
    </Grid>
    

    In the code behind:

    public MainPage()
    {
        this.InitializeComponent();
        this.Loaded += (sender, e) => myMap.Visibility = Visibility.Collapsed;
    }
