Filter XML Data Help Request

programming
1

I have been reading about filtering, XML, CollectionViewSource for days now and I am just as confused as when I started.

I have created a very simple little project in Blend 4…

XML:

<?xml version="1.0" encoding="UTF-8"?>
<dataroot 
xmlns:od="urn:schemas-microsoft-com:officedata" 
generated="2011-06-04T14:21:45">
<Product>
<ID>101</ID>
<Name>Old 
Book</Name>
<Price>10</Price>
</Product>
<Product>
<ID>105</ID>
<Name>New 
Book</Name>
<Price>20</Price>
</Product>
<Product>
<ID>110</ID>
<Name>Video 
Tape</Name>
<Price>25</Price>
</Product>
<Product>
<ID>112</ID>
<Name>Video 
Game</Name>
<Price>30</Price>
</Product>
<Product>
<ID>130</ID>
<Name>Candy 
Bar</Name>
<Price>5</Price>
</Product>
</dataroot>

XAML:


 
<Window
 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"

 <Window.Resources>
  <XmlDataProvider 
x:Key="ProductData" Source="\Product.xml" XPath="dataroot" 
d:IsDataSource="True"/>
  <DataTemplate 
x:Key="DataTemplate1">
   <StackPanel

Width="592.56">
    <TextBlock Text="{Binding

    <TextBlock

Margin="20,0,0,0"/>
    <TextBlock Text="{Binding

Margin="20,0,0,0"/>
   </StackPanel>
  </DataTemplate>
 
 </Window.Resources>
 
 
 <Grid x:Name="LayoutRoot" DataContext="{Binding 
Source={StaticResource ProductData}}" >
  <ListBox 
x:Name="myList" ItemTemplate="{DynamicResource DataTemplate1}" 
ItemsSource="{Binding XPath=/dataroot/Product}" Margin="8,8,0,0" Height="86" 
VerticalAlignment="Top" HorizontalAlignment="Left" 
Width="267"/>
  <Grid x:Name="SelectedItemGrid" 
DataContext="{Binding SelectedItem, ElementName=myList}" Margin="20,98,20,62" 
d:DataContext="{Binding Source={StaticResource ProductData}, 
XPath=/dataroot/Product}">
   <TextBlock 
HorizontalAlignment="Left" VerticalAlignment="Top" Width="100" 
Text="ID"/>
   <TextBlock Text="{Binding XPath=ID}" 
HorizontalAlignment="Left" VerticalAlignment="Top" Width="150" 
Margin="104,0,0,0"/>
   <TextBlock 
HorizontalAlignment="Left" VerticalAlignment="Top" Width="100" 
Margin="0,19.96,0,0" Text="Name"/>
   <TextBlock 
Text="{Binding XPath=Name}" HorizontalAlignment="Left" VerticalAlignment="Top" 
Width="150" Margin="104,19.96,0,0"/>
   <TextBlock 
HorizontalAlignment="Left" VerticalAlignment="Top" Width="100" 
Margin="0,39.92,0,0" Text="Price"/>
   <TextBlock 
Text="{Binding XPath=Price}" HorizontalAlignment="Left" VerticalAlignment="Top" 
Width="150" 
Margin="104,39.92,0,0"/>
  </Grid>
  <Label 
x:Name="filterLabel" Content="Filter ProductId:" HorizontalAlignment="Left" 
VerticalAlignment="Bottom" Margin="8,0,0,23.04"/>
  <TextBox 
x:Name="myFilterBox"
 TextWrapping="Wrap" VerticalAlignment="Top" 
Margin="105.727,174,9,0" 
d:LayoutOverrides="HorizontalAlignment"/>
 </Grid>
</Window>

I tried to follow the Zune XML tutorial posted here, but it was a much older version of Blend and it succeeded in getting me even more confused.

Is there a simple way from within the Blend UI that I can filter my xml generated list using what is typed into the text box?

Any help fot this dumb ditz would be greatly appreciated.
