How can I remove the imagelist binding with the list view at runtime ?

I am getting an error like this

try to delete an image from an imagelist control that I have already used.

You'll need to do a:

Set control.Imagelist = nothing

Here's an example I tried:

when the program loads, I bind the toolbar to the imagelist and then set one of the button images. In the double click event, I unbind the control, remove an image from the imagelist, add a new image, rebind the control and then reset the image. This did appear to work fine.

Private Sub Form_DblClick()

  On Error GoTo Form_DblClick_Error
 
'Unbind imagelist
  Set tbrMain.ImageList = Nothing
'Remove image
  ilsTest.ListImages.Remove 1
'Load in a new image
  ilsTest.ListImages.Add , "test", LoadPicture("D:\FABSUITE\test.ico")
'Rebind imagelist control to toolbar
  Set tbrMain.ImageList = ilsTest
'Rebind button to image
  tbrMain.Buttons(1).Image = "test"

Form_DblClick_exit:
  Exit Sub
 
Form_DblClick_Error:
  MsgBox Err.Description, , "Form_DblClick"
  Resume Form_DblClick_exit
 
End Sub

Private Sub Form_Load()

  On Error GoTo Form_Load_Error
 
'Bind imagelist to toolbar
  Set tbrMain.ImageList = ilsTest
'Bind image to button
  tbrMain.Buttons(1).Image = "test"

Form_Load_Exit:
  Exit Sub
 
Form_Load_Error:
  MsgBox Err.Description, , "Form_Load"
  Resume Form_Load_Exit
 
End Sub



You must set all associated control's Property using your imagelist to nothing
and after your changes set them back

Public Sub ChangeImageList(frm As Form, iml As ImageList)
   
    Dim Ctrl As Control
    Dim Col As Collection

    For Each Ctrl In frm.Controls
        If (TypeOf Ctrl Is TreeView) Or (TypeOf Ctrl Is TreeView) Or (TypeOf Ctrl Is TabStrip) Then
            If Ctrl.ImageList = iml Then
                Set Ctrl.ImageList = Nothing
                Col.Add (Ctrl)
            End If
        End If
    Next Ctrl

    ' change your image list

    For Each Ctrl In Col
        Set Ctrl.ImageList = iml
    Next Ctrl

End Sub



Joy And Happiness
You just unbind all involved controls.
By setting .ImageList = nothing
Now you can remove them.

Hi PatriceF,

Thanks for the answer.. It was really
helpful..

Only thing that needs to be added is
You have to again add the List items
into your listview from the binded imagelist..

thanks,

Amrish
