I try to make a drag and drop with multiple items from a radlisview to a radtreeview while keeping double click in the radlistview to open another window.
I also try with a radlistcontrol but it doesn't work. Could you help me please ?

Hi Olivier,

Thank you for writing.

You can use the RadListView drag and drop service to achieve the desired functionality (which would not affect the double click). For example, you can use the PreviewDragOver and PreviewDragDrop events as follows:
void DragDropService_PreviewDragOver(object sender, Telerik.WinControls.RadDragOverEventArgs e)
{
    RadTreeViewElement el = e.HitTarget as RadTreeViewElement;
    e.CanDrop = el != null;
}
 
void DragDropService_PreviewDragDrop(object sender, Telerik.WinControls.RadDropEventArgs e)
{
    RadTreeViewElement el = e.HitTarget as RadTreeViewElement;
    if (el != null)
    {
        foreach (var item in radListView1.SelectedItems)
        {
            el.Nodes.Add(new RadTreeNode(item.Text));
 
        }
        radListView1.SelectedItems.Clear();
        
    }
}

You can subscribe to this events with the following lines of code:
radListView1.ListViewElement.DragDropService.PreviewDragDrop += DragDropService_PreviewDragDrop;
radListView1.ListViewElement.DragDropService.PreviewDragOver += DragDropService_PreviewDragOver;

Let me know if you have additional questions.
