GalaSoft and Events

I'm using the Galasoft library to attempt to wire up event handling between a view and a viewmodel. There's a discussion of it here[^].

I have a list of customers defined as:

<ListBox ItemsSource="{Binding Customers}"
            Grid.Row="0">

    <i:Interaction.Triggers>
        <i:EventTrigger EventName="ListBoxItem.MouseDoubleClick">
            <g:EventToCommand Command="{Binding ListItemDoubleClickCommandd}" PassEventArgsToCommand="True" />
        </i:EventTrigger>
    </i:Interaction.Triggers>

</ListBox>

In the code behind I have:

private ICommand _ListItemDoubleClickCommand;
public ICommand ListItemDoubleClickCommandd
{
    get
    {
        if (_ListItemDoubleClickCommand == null)
        {
            _ListItemDoubleClickCommand = new RelayCommand(listDoubleClicked);
        }
        return _ListItemDoubleClickCommand;
    }
}

private void listDoubleClicked()
{
}

When I double click a list item, nothing happens. The listDoubleClicked method is never called.

Now, I also added a rectangle:

<Rectangle Fill="LightGray"
            Stroke="Black"
            Width="200"
            Height="100"
            Grid.Row="1">
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="MouseEnter">
            <g:EventToCommand Command="{Binding RectangleMouseEnterCommand, Mode=OneWay}"
                                MustToggleIsEnabledValue="True" />
        </i:EventTrigger>
    </i:Interaction.Triggers>
</Rectangle>

and in the code behind:

private ICommand _RectangleMouseEnterCommand;
public ICommand RectangleMouseEnterCommand
{
    get
    {
        if (_RectangleMouseEnterCommand == null)
        {
            _RectangleMouseEnterCommand = new RelayCommand(rectangleMouseEnter);
        }
        return _RectangleMouseEnterCommand;
    }
}

private void rectangleMouseEnter()
{
    // This does get called
}

The rectangleMouseEnter method does get called. This means my list is wired wrong.
If I change "ListBoxItem.MouseDoubleClick" to "MouseEnter", then it fires. Anyone see what I'm doing wrong?

Thanks

Didn't we answer this same exact question a few weeks ago? You can't handle nested events like that. You can only trap ListBox events there. If you want to trap ListBoxItem events, you need to add that to a ListBoxItem style.

I don't remember. But I took that code straight from his site. I think the reason he had it there is that it seems that you can't do

xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
xmlns:g="clr-namespace:GalaSoft.MvvmLight.Command;assembly=GalaSoft.MvvmLight.Extras.WPF4

.
.
.

<Style x:Key="ListBoxItemStyle" TargetType="{x:Type ListBoxItem}">
    <Style.Triggers>
        <i:Interaction.Triggers>
            <i:EventTrigger EventName="MouseDoubleClick">
                <g:EventToCommand Command="{Binding ListItemDoubleClickCommandd}" 
                                    PassEventArgsToCommand="True" />
            </i:EventTrigger>
        </i:Interaction.Triggers>
    </Style.Triggers>                
</Style>

The style doesn't like this. I'm not sure of the right way to code this. Any ideas?

Add a new Module for a Prism application (WPF)

2-Mar-12 7:41

LOL, you were the one who asked the question Smile | :)

. Anyways, you need to attach the interaction triggers to a Visual, so you need to include the control template unfortunately. The interaction triggers are buried a few lines down Smile | :)

. This does seem a little messy. Your other option is to have a reusable control that forwards the ListBoxItem event to the parent ListBox. That's what I do in my framework, but its a bit more work. One other simpler option might be to just trap the ListBox double click and chase up the visual tree to make sure you clicked on a ListBoxItem.

<Style TargetType="{x:Type ListBoxItem}" BasedOn="{StaticResource {x:Type ListBoxItem}}">
	<Setter Property="Template">
		<Setter.Value>
			<ControlTemplate TargetType="{x:Type ListBoxItem}">
				<Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="true">
					<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
					<i:Interaction.Triggers>
                                            <!-- INSERT HERE -->
					</i:Interaction.Triggers>
				</Border>
				<ControlTemplate.Triggers>
					<Trigger Property="IsSelected" Value="true">
						<Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
						<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}"/>
					</Trigger>
					<MultiTrigger>
						<MultiTrigger.Conditions>
							<Condition Property="IsSelected" Value="true"/>
							<Condition Property="Selector.IsSelectionActive" Value="false"/>
						</MultiTrigger.Conditions>
						<Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}"/>
						<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
					</MultiTrigger>
					<Trigger Property="IsEnabled" Value="false">
						<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
					</Trigger>
				</ControlTemplate.Triggers>
			</ControlTemplate>
		</Setter.Value>
	</Setter>
</Style>

You need to add this new module inside the module catalog or load it via code - this link[^] talks about multiple ways to do this.

You need to add a comctrl6 manifest to your app.

Did you look at the link? It explains step by step Smile | :)

1) create the XML file as shown, you can get rid of the trustinfo section
2) call it yourappname.exe.manifest
3) set the post build command line as shown

You don't use MVC in WPF, you use MVVM.

MemberDotNetting2-Mar-12 10:09

2-Mar-12 10:09

I can use mvc with windows forms?

SledgeHammer012-Mar-12 10:40

2-Mar-12 10:40

You can use whatever you want, I was just pointing out that WPF is specifically designed with MVVM in mind. That doesn't mean you have to use MVVM in WPF. That means that WPF + MVVM is going to provide you with the cleanest code.
