Drag-and-Drop out of Silverlight 5 application

Is it possible to drag items (e.g. images) out of a Silverlight 5 application and drop it to another target (on desktop)? Any ideas if and how this is working? I guess this would be only possbile running the application out-of-browser with elevated trust settings enabled.

This example shows how to drop items INTO a Silverlight application and only mentions that "you cannot drag and drop objects between applications". I also think the link you posted is from 2009. Maybe in Silverlight 5 it is possible to drop FROM the Silverlight app TO another application?

Uhm how do you expect Silverlight to manage the target application, that is where you need to deal with the drop operation. If you could embed the target in the Silverlight app you may have a chance (like the old com object in winforms) but you can't do that anyway.

WPF Calendar (C#)

Cazaceanu Andrei4-Mar-12 7:22

Hello guys!
First I want to say that I'm quite new to WPF and XAML programming languages.

I'm currently trying to make a calendar (Custom Control) in WPF and to be onest I'm not quite sure how to approach this task. Although I've searched all over the internet I couldn't find a pleasing answer. This is the link where I've found some ideas:

http://stackoverflow.com/questions/2125987/create-a-custom-full-sized-calendar-control[^]

Right now I'm thinking on making 3 diffrent Custom Controls which will get combined to create the Calendar. The explications are in the image below:

http://imageshack.us/photo/my-images/851/explicatii.jpg/[^]

I've chosen this approach because will be very easy to create the design and the effects on MouseOver and MouseClick events, but the main problem with it is that I'm not sure on how I can create the logistics of the Calendar:

1st problem: How to bind the data between all of this Controls in order to create the logistics of a basic Calendar;
2nd problem: If the appoiment is longer than 1 day is there a chance to bind the data between this and the next Custom Control (this day and next day, because every day will be a Costum Control).

My question is if this is a good approach? And, if it isn't could you please help me out with some ideas?

Thanks in advance!
Smile | :)

GalaSoft and Events

Kevin Marois2-Mar-12 6:15

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?

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>
