WPF XmlDataProvider and XmlBinding in VB.NET
In this article, I will describe you how XmlBinding will be done using XmlDataProvider in WPF.
WPF also supports binding to Xml data in addition to object and relational data. For instance following example shows family data represented in Xml.
A random family rendered in Xml
<x:XData>
<Company xmlns="http://company.com">
<Employee Name="A" Age="11" />
<Employee Name="B" Age="12" />
<Employee Name="C" Age="38" />
</Company>
</x:XData>
With this file available in the same folder as the executing application, we can bind to it using the XmlDataProvider, as shown below.
<Window x:Class="XmlBinding.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApplication22.XmlBinding"
Title="XmlBinding" Height="325" Width="400">
<Window.Resources>
<XmlDataProvider x:Key="Company" XPath="/sb:Company/sb:Employee">
<XmlDataProvider.XmlNamespaceManager>
<XmlNamespaceMappingCollection>
<XmlNamespaceMapping Uri="http://company.com" Prefix="sb" />
</XmlNamespaceMappingCollection>
</XmlDataProvider.XmlNamespaceManager>
<x:XData>
<Company xmlns="http://company.com">
<Employee Name="A" Age="11" />
<Employee Name="B" Age="12" />
<Employee Name="C" Age="38" />
</Company>
</x:XData>
</XmlDataProvider>
<local:AgeToForegroundConverter x:Key="ageConverter" />
</Window.Resources>
<StackPanel DataContext="{StaticResource Company}">
<ListBox ItemsSource="{Binding}" IsSynchronizedWithCurrentItem="True">
<ListBox.GroupStyle>
<x:Static Member="GroupStyle.Default" />
</ListBox.GroupStyle>
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock>
<TextBlock Text="{Binding XPath=@Name}" />
(age: <TextBlock Text="{Binding XPath=@Age}" Foreground="{Binding XPath=@Age, Converter={StaticResource ageConverter}}" />)
</TextBlock>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<TextBlock>Name:</TextBlock>
<TextBox Text="{Binding XPath=@Name}" />
<TextBlock>Age:</TextBlock>
<TextBox Text="{Binding XPath=@Age}" Foreground="{Binding XPath=@Age, Converter={StaticResource ageConverter}}" />
</StackPanel>
</Window>
