I try to drag a Listview entry to another Listview.
The Drop Listview contains at the moment of the Drop NO Items..

How can I add one Item in this Drop-Event ?

Droping to other Controls is no Problem (ie. Textboxes)
But it i have no idea how to use Drag'n Drop in my Case.........

Any Help is welcome !

Regards

Peter

We tried this and run into problems at first too ;)   The issue for us was
that we tried to add the drop Data object to the second ListView before
either deleting or cloning it from the first ListView.  The ListView
collection requires unque objects to be added to the collection.  If you
catch the exceptions on the DoDragDrop, you will get insight into the actual
problem.

Here is a working sample:

    Private Sub ListView1_ItemDrag(ByVal sender As Object, ByVal e As
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag
        ListView1.DoDragDrop(e.Item, DragDropEffects.Copy)
    End Sub

    Private Sub ListView2_DragEnter(ByVal sender As Object, ByVal e As
System.Windows.Forms.DragEventArgs) Handles ListView2.DragEnter
        If (e.Data.GetDataPresent(DataFormats.Serializable)) Then
            e.Effect = DragDropEffects.Copy
        Else
            e.Effect = DragDropEffects.None
        End If
    End Sub

    Private Sub ListView2_DragDrop(ByVal sender As Object, ByVal e As
System.Windows.Forms.DragEventArgs) Handles ListView2.DragDrop
        Dim item As ListViewItem
        Try
            item = e.Data.GetData(GetType(ListViewItem))
            ListView2.Items.Add(item.Clone)
        Catch ex As Exception
            Debug.WriteLine(ex.Message)
        End Try
    End Sub

Hope this helps.  Regards,
