Binding ViewModel without windows dependency

[Tenjim]

Hi guys,

I search for a viewmodel (Binded to Listbox with Drag and Drop Gong) without windows dependency to have a viewmodel cross-platform.
For that purpose, I want to do it in code behind of the view with the DragHandler/ DropHandler binding. Unfortunately, it doesn't trigger the code behind when I start the drag.

example:

<ListBox
                 DataContext="{Binding ListVm}"
                 ItemsSource="{Binding ListItems}"
                 DragDrop.IsDragSource="True"
                 DragDrop.IsDropTarget="True
                 DragDrop.DragHandler="{Binding RelativeSource={RelativeSource Self}}"
                 DragDrop.DropHandler="{Binding RelativeSource={RelativeSource Self}}" 
</ListBox>

In this case, it'll search into DataContext and not into the code behind of the view.

Do you have any clues about it ?

Thank in advance.

Hi guys,

Finally, I have found a solutions to doing that.

It's the binding need to be on the usercontrol and with that changes ViewModel will not have anymore Windows dependence:

DragDrop.DragHandler="{Binding ElementName=usercontrol}"
DragDrop.DropHandler="{Binding ElementName=usercontrol}"

Thanks.
