An MSForms (all VBA) treeview

Introduction

If you have ever used the Treeview control from the "Additional controls" section, then you know what a versatile control this is to show hierarchically organized data. There are a couple of problems with this Treeview control:

  1. Compile errors due to a difference in how the control libraries are registered in 32 bits Windows' System32 and 64 bit Windows' SysWOW64 folders. If you distribute a file that was saved in 64 bit Windows, containing one of the "Microsoft Windows Common Controls 6.0" (The Treeview control is one of them) and with the reference set to "mscomctl.ocx", people using 32 bit Windows will almost certainly have problems. At best it could entail removing both the control and the reference and replacing both, but at worst the user's Excel can crash when trying to load the file and run the app.
  2. The standard Treeview control, like all non built-in ActiveX controls, cannot be used in 64 bit versions of Office.

Especially the second point convinced me it is time to develop a custom-made Treeview "control", that only uses the native Office forms controls. I started building this a couple of weeks ago and after some time I tricked Peter Thornton into helping me with it

The screenshot below shows both our new Treeview (left) and the Windows one (right) side-by-side in their simplest display mode (read on, there are even prettier screenshots further down the page):

In the following pages I'll show what our treeview can do and explain how to put it to use in your own VBA project.

MAC Office and 64 bit Office Compatible!

Our treeview was tested (and works) on 64 bit Office. It also works on MAC office. Tested applications include:

Excel 2000
Excel 2003
Excel 2010
Excel 2010 (64 bit)
Excel 2011 (MAC Office)
Excel 2013 (32 bit)

Access 2003
Access 2010 (32 bit)
Access 2010 (64 bit)

Acknowledgements

The basic plumbing and code structure of this treeview control was devised by me. However, without the help of my friend and fellow MVP Peter Thornton, lots of functionality would not have been available now. For that I sincerely thank Peter!

Furthermore, Access MVP Ben Clothier was kind enough to make the necessary adjustments to incorporate the treeview in an Access form

Also: Fellow Excel MVP Ron De Bruin ensured the treeview also works on MAC Office 2011, Thanks Ron!

However, we're offering this treeview to you at no cost. You get an unrestricted license for use in any VBA project you like. You're free to modify any part of the code at will.

We do have some rules:

And please mention the source of the treeview (including a link to this page) in your helpfile, manual and/or on your about screen.

We're always interested to see how people have implemented the VBA Treeview. So please feel free to send a screenshot with a brief description or relevant details.

Donations

Many, many hours were spent developing this treeview. Although we developed it for use in our own projects, we are giving it away for free!

Nevertheless, we would really be pleased if you actually express your appreciation in a more "tangible" form. So here is a paypal donation button at your disposal:

Download

The Excel workbook contains most of the documentation (on the tabs of the workbook), so I recommend you to at least download the Excel version. The Access version has instructions on its main form (click the "How do I...?" button) on how to implement the treeview in your own projects.

Download the treeview sample Excel workbook (including documentation) (build 026, 15 Oct 2015, downloaded 30,964 times)

Download the treeview sample Word document (build 026, 15 Oct 2015, downloaded 9,602 times)

Download the treeview sample Access database (build 025, 16 Oct 2013, downloaded 25,090 times)

‘Pro’ Treeview and ListGrid VBA controls

The professional version of the treeview control has exceptional performance. Even with tens of thousands of nodes it will load quickly and remain highly responsive. It also has several new features including drag and drop.

Our new ListGrid combines most of the functionality of the ActiveX Listview and Flexgrid controls with many extra useful features. It is the result of extensive beta testing by some of our treeview users, thanks guys!

The screenshot of the demo below gives an idea of just some of its capability.

Professional ListGrid control

The Pro Treeview and ListGrid are available for 32/64 bit Excel and Access. The Excel version will also work in Mac, one or two features are disabled for Mac but we’re working on it. Unlike our free treeview they are self contained in their own files and designed to work more like real controls.

For more details and if interested to try either of these ‘controls’ please contact us:

Please note that the pro versions are paid versions. Pricing available upon request by using the links above.

Other controls

Another often used control is the calendar control. This control has the added problem that it has been deprecated with Office 2010 (where we're supposed to use the date picker control). Frankens Team created an all-vba alternative using very similar techniques to what we've done here.

Ron de Bruin created a Date Picker control for MAC Excel.

We are currently developing a listgrid/listview control. Contact us if you would like to participate in the beta program. Note that this control will not be made available as freeware.

Goede morgen uit Leipzig!
ik zoek naar een mogelijkheid bij treeview met mouse-over additionele en verdiepende informaties te geven over de node die zo wordt geraakt.
Is dat mogelijk/hoe kann dat mogelijk worden gemaakt?

 


Comment by: Jan Karel Pieterse (8/4/2018 8:35:19 PM)

Hoi Jan,

Je zou zelf een eigenschap kunnen toevoegen die de controltiptext vult van de controls van de node.

This treeview control is absolutely great. Much faster to render a tree than the 32 bit MS Treeview control. Similar in syntax, so easy to learn if you've used the latter, and very thorough and feature-rich.

I will be making a Paypal donation, and thanks for an awesome effort and for generously making it available.

Hi Ian,

Thanks!

Hi guys,

this is absolutely amazing control!
I am using it with Access 2016 64bit and it works beautifully and it is very fast.

I know this is a trivial issue, but I am struggling with trying to get the treeview border to look flat rather than sunken. I have tried changing the border property to "transparent" and specialeffect property to "flat" everywhere but with no success...any help?

I'd like to make it look like the XER toolkit in the example list of your website.

Thank you

Hi Luigi,

You change that by changing the appearance of the frame you placed on the userform yourself (the one called frTreeControl in the Excel demo).

A suggestion to enhance the FullPath function for some compatibilty with the fullpath property in the ms treeview control:

Public Enum ndPathType
    ndKeys = 1
    ndCaptions = 2
End Enum

Public Function FullPath(Optional ByVal ndType As ndPathType = ndKeys) As String
' PT, get all the grand/parent keys
' assumes use of key

Dim s As String
Dim cNode As clsNode

On Error GoTo errDone
Set cNode = Me

If ndType = ndKeys Then
     s = Me.Key
     While Err.Number = 0
         Set cNode = cNode.parentNode
         s = cNode.Key & "\" & s
     Wend
Else
     s = Me.Caption
     While Not cNode.parentNode.Caption = "RootHolder"
         Set cNode = cNode.parentNode
         s = cNode.Caption & "\" & s
     Wend
End If

errDone:
FullPath = s
End Function
