MouseBinding/LeftDoubleClick on a ListBox does not work

Question

Hi,

 

I have a ListBox in my WPF Application. Now I want to connect the ListBox to a command, which is responsible for opening the current selected item. This command is also use for ToolButtons or the ContextMenu.

 

I tried the following:

 

Code Snippet

<Window.CommandBindings>

  <CommandBinding

       Command="ApplicationCommands.Open"

       CanExecute="OpenCustomer_CanExecute"

       Executed="OpenCustomer_Executed" />

</Window.CommandBindings>

 

<ListBox

    ItemsSource="{Binding ...}"

    ItemTemplate="{StaticResource ...}">

  <ListBox.InputBindings>

    <KeyBinding

        Key="Enter"

        Command="ApplicationCommands.Open" />

    <MouseBinding

        MouseAction="LeftDoubleClick"

        Command="ApplicationCommands.Open" />

  </ListBox.InputBindings>

</ListBox>

 

If I press ENTER the command will be executed. But the MouseDoubleClick does not work.

 

Answer 1

Hi Joe,

Did you find a solution to the ListBox consuming the LeftDoubleClick MouseAction? I'm looking into it now but thought you may have an answer.

cheers.

Answer 2

I have the same probleme.

 

The listbox consumes the Mouse Double Click only when the Double Click is on a Listbox Item. If die Double Click is inside the free space of the ListBox, where no ListBox Item is, the click is handled appropriate.

Answer 3

I think you may  use attached property to achieve this. The below thread has a discussion about the same.

Hi Jose!

 

Nice solution :-)

I have another one:

 

                  <ListBox.ItemTemplate>
                    <DataTemplate>
                      <TextBlock Text="{Binding Name}">
                        <TextBlock.InputBindings>
                          <MouseBinding Command="somecommand" Gesture="LeftDoubleClick"/>
                        </TextBlock.InputBindings>
                      </TextBlock>
                    </DataTemplate>
                  </ListBox.ItemTemplate>

 

Is more inefficient than your solution, but works good too.

Answer 5

Hi all,

    I was about to create a new thread for the mouse double click issue, but I stumbled upon this thread. I also have the same problem with mouse double click on a listbox. The keyboard "enter" works fine though. I tried the solution suggested by Alex, but it doesn't seem to work. I can't use attached property since I need to be able to call my non-static methods in order to do some operation. So, is there any other alternative for this issue or am I missing something?

 

Regards,

Hi Vikhyath,

 

I used my obove solution, but I think it is inefficient. So now I do it the old way again, by registering to the MouseDoubleClick event in code. I tryed a lot, but I didn't get it to work with commands in an efficient way. So I call the commands in code.

 

_ListBox.MouseDoubleClick += new MouseButtonEventHandler(_ListBox_MouseDoubleClick);

 

    void _ListBox_MouseDoubleClick(object sender, MouseButtonEventArgs e)
    {
      if (e.ChangedButton == MouseButton.Left)
      {
        if (MyCommands.SomeCommand.CanExecute(null, _ListBox))
        {
          e.Handled = true;
          MyCommands.SomeCommand.Execute(null, _ListBox);
        }
      }
    }

And don't forget to set the commandbinding somewhere, maybe at your listbox or at some parent control of the listbox. You can do this in XAML too.

 

this.CommandBindings.Add(new CommandBinding(MyCommands.SomeCommand, new ExecutedRoutedEventHandler(SomeCommand_Executed), new CanExecuteRoutedEventHandler(SomeCommand_CanExecute)));
      

 

Answer 7

Thanks Alex!

But, I am using MVVM pattern, so I guess your solution may not be feasible. Any idea on how this can be achieved in MVVM?

I have been struggling with this issue for quite sometime now...

Hey Vikhyath,

 

I'm very sorry, but I don't know how to solve this in MVVM.

This bug is realy annoying.

 

 

Answer 9

No problem Alex.

Is there anyone here who has a solution to this problem?

Have a look at EventBurglar (at the bottom of the thread) you can use it to hook up events to a command in your view model.

If you put it on the listbox it will use the listbox datacontext to resolve the handler. If you put it on the ListBoxItem it will use the ListBoxItem's datacontext to resolve the handler.

Answer 11

See this documentation.

It's written for the Catel MVVM framework, but it will work for all frameworks that support EventToCommand.

That's it! Thank you for the link!

Answer 13

I used a small library 'AttachedCommandBehavior' for this.

xmlns:acb="clr-namespace:AttachedCommandBehavior;assembly=AttachedCommandBehavior"

<Style TargetType="{x:Type ListBoxItem}">
	<Setter Property="acb:CommandBehavior.Event" Value="MouseDoubleClick" />
	<Setter Property="acb:CommandBehavior.Command" Value="{Binding DataContext.DoubleClickCommand, RelativeSource={RelativeSource FindAncestor, AncestorType=Window}}" />
	<Setter Property="acb:CommandBehavior.CommandParameter" Value="{Binding}" />
</Style>

You can get this library from http://marlongrech.wordpress.com/2008/12/13/attachedcommandbehavior-v2-aka-acb/

If you don't want to use this library, you can write a attached behavior on your own.

Please mark it as answer it if suffices your requirement.

Answer 16

Hi

I used Expression SDk 4.0

xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"

<i:Interaction.Triggers>
  <i:EventTrigger EventName="MouseDoubleClick" SourceName="CaravanasListBox">
     <i:InvokeCommandAction Command="{Binding AccionesToolbarCommand}" CommandParameter="{x:Static local:OpcionesBarra.MostrarDetalle}" />
   </i:EventTrigger>
</i:Interaction.Triggers>
