Ratnesh,

   Here is some sample code:

The following are variables used for the D&D processsing of mouse moves.

   Private _MouseDown As Boolean = False
   Private _MouseX As Integer
   Private _MouseY As Integer
   Private _MouseButtons As MouseButtons
   Private _SwitchContext As Boolean = False

The following happens when the mouse button is pressed over my listview

   Private Sub List_MouseDown(ByVal sender As System.Object, ByVal e As
System.Windows.Forms.MouseEventArgs) Handles SongFileView.MouseDown
       _MouseButtons = e.Button
       _SwitchContext = False
       _MouseDown = True
       _MouseX = e.X
       _MouseY = e.Y
   End Sub

The following happens on a move of the mouse.  I use a test for the distance
the mouse has moved to prevent false drag drop operations:

   Private Sub List_MouseMove(ByVal sender As System.Object, ByVal e As
System.Windows.Forms.MouseEventArgs) Handles SongFileView.MouseMove
       Dim lv As ListView = DirectCast(sender, ListView)
       Dim sc As New StringCollection

       If _MouseDown Then
           If Math.Abs(_MouseX - e.X) < 5 Or Math.Abs(_MouseY - e.Y) < 5
Then
               Exit Sub
           End If
           Dim xx As DataObject = New DataObject
           Dim yy As ArrayList = New ArrayList
           For Each idx As Integer In lv.SelectedIndices
               Dim li As ListViewItem = lv.Items(idx)
               yy.Add(li.SubItems(5).Text + "\" + li.Text)
               sc.Add(li.SubItems(5).Text + "\" + li.Text)
           Next

           Dim zz As Array = yy.ToArray
           xx.SetFileDropList(sc)
           xx.SetData("ListItems", lv.SelectedItems)
           Try
               lv.DoDragDrop(xx, DragDropEffects.Copy)
               _MouseDown = False
           Catch ex As Exception
               Dim zzzz As Integer = 1
           End Try

       End If
   End Sub

The following will reset the D&D if the mouse button is release over the
listview:

   Private Sub SongFileView_MouseUp(ByVal sender As System.Object, ByVal e
As System.Windows.Forms.MouseEventArgs) Handles SongFileView.MouseUp
       _MouseDown = False
   End Sub

Hope this helps:
