Data binding to static resource: shown to work in VS but not when run

[Jonathan Davies]

Hi, I'm following a Data Binding example from: microsoft[^] which displays the expected result in the VS2008 design window on XP but not when I run it. The XML looks OK to me with the XMLDataProver in a Resource :

<XmlDataProvider x:Key="MoreColors" XPath="/colors">

and the ListBox attribute :

ItemsSource="{Binding Source={StaticResource MoreColors}, XPath=color/@name}">

, any ideas why it displays data in the ListBox in design mode in VS2008 but doesn't display any data in the ListBox when its run?

<Window x:Class="WpfText2LableBinding.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">

<StackPanel>
    <StackPanel.Resources>
        <XmlDataProvider x:Key="MoreColors" XPath="/colors">
            <x:XData>
                <colors >
                    <color name="pink"/>
                    <color name="white"/>
                    <color name="black"/>
                    <color name="cyan"/>
                    <color name="gray"/>
                    <color name="magenta"/>
                </colors>
            </x:XData>
        </XmlDataProvider>
    </StackPanel.Resources>

    <TextBlock Width="248" Height="24" Text="Colors:" TextWrapping="Wrap"/>

   <ListBox x:Name="lbColor" Width="248" Height="56" IsSynchronizedWithCurrentItem="True" 
        ItemsSource="{Binding Source={StaticResource MoreColors}, XPath=color/@name}">
   </ListBox>
        
</StackPanel>

</Window>

I answered this here[^]. Add the namespace I mention in the answer and you are good to go.

Thanks, you identified the cause though I think your linked solution is wrong (in this case anyway). It's now working but I had to use: <x:XData> <colors xmlns=""> rather then the <x:XData xmlns=""> <colors > in your link. I found another MS example which uses xmlns in this manner:

<StackPanel.Resources>
<XmlDataProvider x:Key="InventoryData" XPath="Inventory/Books">
<x:XData>
<Inventory xmlns="">
