WPF phone 8 The attachable property Resources was not found in type DataTemplate

I'm trying to kick out a DataTemplate at runtime for the ListBox's ContentTemplateSelected. The data types and values are not known at runtime. Here's an example of one. When I call this:

var dataTemplate = (DataTemplate)XamlReader.Load(xaml.ToString());

on the generated xaml:

<DataTemplate xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:converters="clr-namespace:DSI.MyProject.Converters;assembly=DSI.MyProject"
>
    <DataTemplate.Resources>
        <converters:StringValueToBoolConverter x:Key="stringValueToBoolConverter" />
    </DataTemplate.Resources>   
    <Grid>
      <Grid.ColumnDefinitions>
         <ColumnDefinition Width="128" />
      </Grid.ColumnDefinitions>
      <Border BorderThickness="1" BorderBrush="Black" Grid.Column="0" Background="{StaticResource PhoneContrastBackgroundBrush}" >
          <CheckBox IsChecked="{Binding [CheckEd], Mode=TwoWay}" Padding="2" HorizontalAlignment="Left" />
      </Border>
   </Grid>
</DataTemplate>

I get the error:

The attachable property Resources was not found in type DataTemplate

Am I missing something in the includes?

Even though this example doesn't use it, the converter will be used in the IsChecked binding.

It seems to work for this person: Dynamically added DataTemplate - StaticResource for Converter can't be found

My original issue: WPF using converter in datatemplate created from xaml text and XamlReader on phone 8

I think you are confusing WPF behavior with the SilverLight XAML distribution for Windows and Windows Phone 8. Unfortunately, Resources is a property of the FrameworkElement base class, while DataTemplate derives from the lower level DependencyObject class. As such, it does not support a resource collection.

As a fix, consider making the converter part of your Application or Page resources rather than part of the DataTemplate directly.
