I have a DataTemplate with a ListView control. This DataTemplate is
located in Templates.xaml (which is a ResourceDictionary). Template.xaml
is then included into my main UserControl SourceManager.xaml through
ResourceDictionary.MergedDictionaries. I want to raise the
SelectionChanged event of the DataTemplate's ListView but I want the
handler in the code behind to be in SourceManager.xaml.cs.
How can I achieve that?
Templates.xaml:
<ResourceDictionary x:Class="LawBib.Templates"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<DataTemplate x:Key="SectionTemplate">
<StackPanel>
<TextBlock Text="{Binding XPath=@Title}" />
<ListView x:Name="GroupList" ItemsSource="{Binding XPath=Source}">
<ListView.Template>
<ControlTemplate>
<WrapPanel IsItemsHost="True">
</WrapPanel>
</ControlTemplate>
</ListView.Template>
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel>
<Image Source="images/source.png" />
<TextBlock Text="{Binding XPath=@Title}" HorizontalAlignment="Center" />
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackPanel>
</DataTemplate>

SourceManager.xaml:
<UserControl x:Class="LawBib.SourceManager"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300" Background="#f5f7f8">
<UserControl.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Resources.xaml" />
<ResourceDictionary Source="Templates.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</UserControl.Resources>
...
</UserControl>
