we are using 8.2.20082.1000

we are using lots of the common controls, grid, combo, texteditor, etc.

We just want to know if the memory leak issue have been fixed (I believe that this issue is common and have been raised on multiple occassion).

Hello,

Have you verified that Dispose is being called on the Form?  If you have a break point in the method, does it get hit?

Been struggling with this for a while now.  I tried disposing the controls by overriding the dispose event on my form and then disposing of each control however the controls are still staying in memory.

<System.Diagnostics.DebuggerNonUserCode()> _
    Protected Overrides Sub Dispose(ByVal disposing As Boolean)
        Try

 'On Error Resume Next
        'tracker issue 922 - memory leak
        For Each ctl As Control In ParentControl.Controls
            Try
                If ctl.HasChildren Then DisposeFormControls(ctl)
                If ctl.Name <> "" Then
                    ctl.Dispose()
                End If
            Catch ex As Exception
            End Try
        Next

  Finally
            MyBase.Dispose(disposing)
        End Try

        GC.Collect()

    End Sub

What did I miss?

We're aware of it, and are considering it for future releases.  To my knowledge, it hasn't been specifically included in any particular release.  Given the size of the changes required, we have to balance this against other development time, so we're handling it much like we would a request for a new feature.

Is the weak ref strategy planned for a near release, or it is just too big of a change?

Thanks - that clarifies the issue significantly.

There were some discussion about the control hooking to a static event for the styling of the app. Which causes the controls to never be GC because of that static event.

If you're showing your form modally using ShowDialog(), then this automatic disposal of the form doesn't happen.  This is correct behavior in Windows Forms.  The solution here is to dispose of your form expliciitly, which will then dispose its child controls.

If you've created controls but haven't added them to a Controls collection, such as by storing them in a field of your form class, they won't be automatically disposed.  In this case, you must explicitly dispose these controls.  This the situation where our controls hooking static events causes an issue.  Changing this will require significant rearchitecture, likely including implementation of a "weak reference" event handler, and has not yet been done.
