I have a ListView with an ItemSource that is bound to some XML, via {Binding 
Xpath=...}.  The ListView.View is defined with a GridView.  In the individual 
GridViewColumn elements, I'd like to specify DisplayMemberBinding, and bind 
to the various XML elements.  If my XML is specified with the default 
namespace, then everyting works like a charm:

<GridViewColumn Header="Name" DisplayMemberBinding="{Binding XPath=name}" />

However, my production XML relies on several namespaces, and so my 
production XML element names have a prefix.  When I change my XAML code to 
use an XmlNamespaceManager, everything ELSE works with the prefixed XPaths, 
except for the GridViewColumns.  Thus the following:

<GridViewColumn Header="Name" DisplayMemberBinding="{Binding 
XPath=cap:name}" />

doesn't work.  Found a solution (somewhere on the Internet) that proposed 
switching from DisplayMemberBinding to using a CellTemplate, but that didn't 
work either.

Any other ideas?

Hi Jim,


This is a quick note to let you know that I am performing research on this 
issue and will get back to you as soon as possible. I appreciate your 
patience.

Hi Jim,

I've done some research and following code works on my side:

<Window x:Class="WpfApplication1.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">
    <Window.Resources>
        <XmlNamespaceMappingCollection x:Key="mapping">
            <XmlNamespaceMapping Uri="http://foo" Prefix="foo" />
        </XmlNamespaceMappingCollection>

        <XmlDataProvider x:Key="Books" Source="Books.xml" 
XmlNamespaceManager="{StaticResource mapping}" />
    </Window.Resources>
    <StackPanel>
        <TextBlock>ListView</TextBlock>
        <ListView>
            <ListView.ItemsSource>
                <Binding Source="{StaticResource Books}" 
XPath="foo:Books/foo:Book" />
            </ListView.ItemsSource>
            <ListView.View>
                <GridView>
                    <GridViewColumn Header="Name" 
DisplayMemberBinding="{Binding XPath=foo:Name}" />
                </GridView>
            </ListView.View>
        </ListView>
        <TextBlock>ListBox</TextBlock>
        <ListBox>
            <ListBox.ItemsSource>
                <Binding Source="{StaticResource Books}" 
XPath="foo:Books/foo:Book"/>
            </ListBox.ItemsSource>
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding XPath=foo:Name}">
                    </TextBlock>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
    </StackPanel>
</Window>


Books.xml

<?xml version="1.0" encoding="utf-8" ?>
<foo:Books xmlns:foo="http://foo">
	<foo:Book>
		<foo:Name>First</foo:Name>
		</foo:Book>
</foo:Books>



Please test this and let me know the result. Thanks.

Your ListView didn't work on my machine.  I modified your code, a little, to 
make sure that the ListView was doing anything.  The modified code is:

  <StackPanel>
    <TextBlock>ListView</TextBlock>
    <ListView ItemsSource="{Binding Source={StaticResource Books}, 
XPath=foo:Books/foo:Book}" >
      <ListView.View>
        <GridView>
          <GridViewColumn Header="Name1" DisplayMemberBinding="{Binding 
XPath=foo:Name}" />
          <GridViewColumn Header="Row?" >
            <GridViewColumn.CellTemplate>
              <DataTemplate>
                <TextBlock Text="A Row" />
              </DataTemplate>
            </GridViewColumn.CellTemplate>
          </GridViewColumn>
        </GridView>
      </ListView.View>
    </ListView>
    <TextBlock>ListBox</TextBlock>
    <ListBox ItemsSource="{Binding Source={StaticResource Books}, 
XPath=foo:Books/foo:Book}" >
      <ListBox.ItemTemplate>
        <DataTemplate>
          <TextBlock Text="{Binding XPath=foo:Name}" />
        </DataTemplate>
      </ListBox.ItemTemplate>
    </ListBox>
  </StackPanel>

I also added 3 more <foo:Book> nodes into Books.xml.  When I run the 
application, the window looks like this:

----------------------------------------
| ListView
| Name1   Row?
|              A Row
|              A Row
|              A Row
|              A Row
| ListBox
| First
| Second
| Third
| Fourth
----------------------------------

Given that your code works properly on your machine, I have to conclude that 
the problem is in the particular release of the .Net 3.0 WPF assemblies 
installed on my computer.  

Here's where I get a little confused.  In my VS2005 project file, the 
references for PresentationCore and PresentationFramework both go to dlls in 
"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.0".  
Those DLLs are listed as "Runtime Version v2.0.50727, Version 3.0.0.0".

However, my GAC contains different versions of the same 2 assemblies: the 
GAC assemblies are marked as "Product Version 3.0.6912.0 Version 3.0.0.0" 
(BTW, I'm doing this testing on a Vista Business 64-bit system).  

Have I installed out-of-date copies of the WPF/WCF Framework SDKs?

Hi Jim,

After further testing, this looks like an issue of .NET Framework 3.0 but 
fixed in .NET Framework 3.5 Beta 2. Please install .NET Framework 3.5 Beta 
2 from here:

#Download details: .NET Framework 3.5 Beta 2
http://www.microsoft.com/downloads/details.aspx?familyid=d2f74873-c796-4e60-
91c8-f0ef809b09ee&displaylang=en

We're sorry for the inconvenience caused by this. I'll file a bug for it.

Please note the RTM version of .NET Framework 3.5 is scheduled to be 
released at end of 2007; beta 2 of it is also included in VS2008 (aka 
Orcas) beta 2, which can be downloaded here: 
http://msdn2.microsoft.com/en-us/vstudio/aa700831.aspx

Thanks for the info, Walter.  I'll pass the word about those 2 beta versions 
around here at my company.
