Drag and Drop with two listviews.

[paulablanca]

Hi guys! I need some help. I have two listviews that uses drag and drop to pass values, however I can only pass the value of my first column. What I need is to pass the value of my two columns. Thanks! God Bless.! :)

You should be able to copy and paste this into a new project.

Public Class Form1

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        'Adds to listview items to the form

        Me.Size = New Size(400, 400)
        Me.Controls.Clear()

        Dim Listview1 As New ListView
        Dim Listview2 As New ListView

        Listview1.Location = New Point(50, 50)
        Listview1.Name = "ListView1"

        Listview2.Location = New Point(200, 50)
        Listview2.Name = "ListView2"

        Me.Controls.Add(Listview1)
        Me.Controls.Add(listview2)

        For Each c As Control In Me.Controls
            If TypeOf c Is ListView Then
                With CType(c, ListView)
                    .AllowDrop = True
                    .Columns.Add("Name")
                    .Columns.Add("Type")
                    .FullRowSelect = True
                    .MultiSelect = False
                    .Size = New Size(150, 300)
                    .View = View.Details
                    AddHandler .ItemDrag, AddressOf ListView_ItemDrag
                    AddHandler .DragEnter, AddressOf ListView_DragEnter
                    AddHandler .DragDrop, AddressOf ListView_DragDrop

                    .Items.Add(New ListViewItem(New String() {c.Name, 1}))
                End With
            End If
        Next

    End Sub

    Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemDragEventArgs)
        If sender Is Nothing OrElse Not TypeOf sender Is ListView Then Exit Sub

        With CType(sender, ListView)
            .DoDragDrop(e.Item, DragDropEffects.Move)
        End With
    End Sub

    Private Sub ListView_DragEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs)
        If sender Is Nothing OrElse Not TypeOf sender Is ListView Then Exit Sub

        'If this is a listview item then allow the drag

        If e.Data.GetDataPresent(GetType(ListViewItem)) Then
            e.Effect = DragDropEffects.Move
        End If

    End Sub

    Private Sub ListView_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs)
        If sender Is Nothing OrElse Not TypeOf sender Is ListView Then Exit Sub

        'Remove the item from the current listview and drop it in the new listview
        With CType(sender, ListView)

            If e.Data.GetDataPresent(GetType(ListViewItem)) Then

                Dim draggedItem As ListViewItem = CType(e.Data.GetData(GetType(ListViewItem)), ListViewItem)

                draggedItem.ListView.Items.Remove(draggedItem)

                .Items.Add(draggedItem)
            End If

        End With

    End Sub

End Class
