Dragging Listbox Items within same listbox up/down

[LOSS1574]

the below code works for a single column listbox. However I need to adjust the code to allow dragging within a four column listbox...


Private Sub lstMulti_BeforeDropOrPaste(ByVal Cancel As MSForms.ReturnBoolean, _
ByVal Action As MSForms.fmAction, _
ByVal Data As MSForms.DataObject, _
ByVal X As Single, _
ByVal Y As Single, _
ByVal Effect As MSForms.ReturnEffect, _
ByVal Shift As Integer)

Dim lTo As Long

With Me.lstMulti
lTo = .TopIndex + Int(Y * 0.85 / .Font.Size)
If lTo >= .ListCount Then lTo = .ListCount
Cancel = True
Effect = fmDropEffectMove
.AddItem Data.GetText, lTo
If mobjFromList = Me.lstMulti And lTo < mlFrom Then
mobjFromList.RemoveItem (mlFrom + 1)
Else
mobjFromList.RemoveItem mlFrom
End If
Set mobjFromList = Nothing
End With
End Sub

Thank you,

You will need to iterate the Column property most likely. An attached xls would help us help you more easily.

Any help with this issue would be appreciated...

Move and drag item with Mouse for a four column listbox

[Kenneth Hobs]

I will have to rework what I was working on for this. I was able to create a string using the BoundColumn property in a loop. However, the tab delimiter that I added to not match what the range set so I will have to think on this more.

The lTo is a bit confusing.

ByVal Effect As MSForms.ReturnEffect, _
ByVal Shift As Integer)

Dim lTo As Long

With Me.lstMulti
lTo = .TopIndex + Int(Y * 0.85 / .Font.Size)
If lTo >= .ListCount Then lTo = .ListCount
Cancel = True
Effect = fmDropEffectMove
.AddItem Data.GetText, lTo
If mobjFromList = Me.lstMulti And lTo < mlFrom Then
mobjFromList.RemoveItem (mlFrom + 1)
Else
mobjFromList.RemoveItem mlFrom
End If
Set mobjFromList = Nothing
End With

Keith:

Thanks for the code. I'm getting an error message when i attempt to move the last item in the listbox up..

If mobjFromList = Me.lstMulti And lTo < mlFrom Then
mobjFromList.RemoveItem (mlFrom + 1) -------------This line
Else
mobjFromList.RemoveItem mlFrom
End If
Set mobjFromList = Nothing
End With

I will have to think about your logic some more. As you can see from multiple moves in the Immediate window with debug, your code is removing items. Try moving the 3rd to the 2nd, twice. The ListCount should not be changing.

Private Sub lstMulti_BeforeDropOrPaste(ByVal Cancel As MSForms.ReturnBoolean, _
ByVal Action As MSForms.fmAction, _
ByVal Data As MSForms.DataObject, _
ByVal X As Single, _
ByVal Y As Single, _
ByVal Effect As MSForms.ReturnEffect, _
ByVal Shift As Integer)
Dim r As Range, s As String
Dim i As Integer

Dim lTo As Long

With Me.lstMulti
lTo = .TopIndex + Int(Y * 0.85 / .Font.Size)
If lTo >= .ListCount Then lTo = .ListCount
Cancel = True
Effect = fmDropEffectMove

Set r = Range(Cells(Rows.Count, 1), Cells(Rows.Count, .ColumnCount))
For i = 1 To .ColumnCount - 1
.Column(i, lTo) = aItem(i)
Next i

If mobjFromList = Me.lstMulti And (lTo < mlFrom) Then
Debug.Print 1, mlFrom, lTo, .ListCount
mobjFromList.RemoveItem (mlFrom + 1)
Else
Debug.Print 1, mlFrom, lTo, .ListCount
mobjFromList.RemoveItem mlFrom
End If
Set mobjFromList = Nothing
End With
End Sub

I will probably look at what Andy Pope did in: http://www.ozgrid.com/forum/showthread.php?t=58952
The code there is shown below. You can get Andy's xls or use his code below for a UserForm with ListBox1.
