Question

In WPF I have a listview that is bound to an ObservableCollection.

XAML:

<ListView Name="listView" DockPanel.Dock="Top" ItemsSource="{Binding Path=ListOfOldData}" SelectedItem="{Binding Path=SelectedOldData, Mode=TwoWay}" SelectionMode="Single">
        <ListView.ContextMenu>
            <ContextMenu>
              <Button Content="Load" Command="{Binding Path=LoadCommand}"  Name="loadButton" Height="23" Width="75" DockPanel.Dock="Left"/>             
              <!-- Is working just fine -->         
            </ContextMenu>
        </ListView.ContextMenu>
        <ListView.ItemTemplate>
            <DataTemplate>
                <TextBlock MouseLeftButtonDown="TextBlock_MouseLeftButtonDown"
                           Text="{Binding Path=Name}" FontWeight="Bold"><TextBlock Text=" - " FontWeight="Normal"/><TextBlock Text="{Binding Path=UpdateDatum}" FontWeight="Normal"/></TextBlock>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>

What I actually wanted to receive is a double-click on the selected-item. As I can’t bind a command to a textblock in xaml (can I?) I tried doing this via the MouseLeftButtonDown-Event. But the event is never received!

C# (in code behind):

private void TextBlock_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    Console.WriteLine("MouseLeftButtonDown received!");
}

What am I doing wrong? How can I receive the event? Btw.: The command of the contextmenu is working just fine 🙂

UPDATE I found my error –> I added the event in the wrong usercontrol. Damn my missing concentration. Sorry for bugging you all.

The ListView has a DoubleClick MouseEvent.
This should do it :

<ListView MouseDoubleClick="DoubleClickOnIt">
   <ListView.ItemTemplate>
      <DataTemplate>
         <TextBlock Text="{Binding Path=Name}" FontWeight="Bold">
            <TextBlock Text=" - " FontWeight="Normal"/>
            <TextBlock Text="{Binding Path=UpdateDatum}" FontWeight="Normal"/>
         </TextBlock>
      </DataTemplate>
   </ListView.ItemTemplate>

   <ListViewItem>
      dddd
   </ListViewItem>
   <ListViewItem>
      eeeee
   </ListViewItem>
</ListView>

And the code behind :

private void DoubleClickOnIt(object sender, MouseButtonEventArgs e)
{
   var listView = sender as ListView;
   var selectedItem = listView.SelectedItem;
   Console.WriteLine("received!");
}
