How to drag and drop between two instances of the same application?

[Martin]

My application contains a RadListbox and I'd like to drag and drop items in this RadListBox from one instance of my application to another instance. How can I accomplish this?

It's similar to wanting the CustomDragVisualStyle_WPF example to support drag and drop between instances instead of just allowing drag and drop within one instance.

I got it working with copy/paste buttons, but I also want to support drag and drop.

Hi Martin,

What I can suggest you would be to check the following article which explains how to achieve the desired:
http://wpf.2000things.com/2012/12/05/705-dragging-a-custom-object-using-serialization-as-format/

You will need to add the [Serializable] attribute to your custom object and using the DragDropManager in the DragInitialize method to create new Serializable DataObject as shown below:

private void OnDragInitialize(object sender, DragInitializeEventArgs e)
{
    e.AllowedEffects = DragDropEffects.All;
    e.Data = new DataObject(DataFormats.Serializable, new Customer { FullName = "Customer" });
    e.Handled = true;
}

Afterwards on Drop in the second instance of the Application you can get the object the following way:

private void OnDrop(object sender, Telerik.Windows.DragDrop.DragEventArgs e)
{
    var data = (e.Data as DataObject).GetData(DataFormats.Serializable) as Customer;
}

Hope this will help you to achieve the required.
