An MSForms (all VBA) treeview for Access, Excel And Word

Content

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 to develop a custom-made Treeview "control", that only uses the native Office forms controls. A couple of weeks after I started building this 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 works in all versions of Excel, Access and Word; from Office 2007 to 2019 and 365, for Windows and Mac, 32bit and 64bit. It also works in some earlier versions though you would need to adapt the demos made for 2007 and later.

Acknowledgements

The basic plumbing and code structure of this treeview control was devised by me. However, without the help of my friend and fellow (former) Excel 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!

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.

‘Pro’ Treeview and ListGrid VBA controls

If your project needs more features and/or better performance than our free treeview, or if you need a listgrid control you've come to the right place as well.

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. Timing experiments have shown that the pro version of our treeview outperforms the common controls treeview.

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 in a trial license 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 (The download files above contain a Word document which also gives more details about the pro controls).

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.

is there a special procedure for adding extra icons to the frImages-frame? By using the toolbox I can add an extra image to the frImages-frame bit i cannot picture property.

Hi Jo,

In which application are you using the treeview? If in MSAccess you may have to draw the images on a regular userform window in Excel and then copy-paste them into the Access subform.

Hi,

Brilliant tool, thank you for sharing!

I am running into an issue when trying to add an image to an existing node.

I am using:


    Set cNode = mcTree.ActiveNode
    
    cNode.ImageMain = "Alert"
    cNode.ImageExpanded = "Alert"
    cNode.Expanded = Not cNode.Expanded
    mcTree.Refresh


However what is happening is that the image is being inserted over the caption, pushing the caption onto the next line which is then obscured by the next node, rather than to the left of the caption.

What am I missing?

Thanks!

Hi Ian,

Thanks! If you look at the Treeview Excel demo file, you'll see the images of a node are set when adding the nodes in question, have a look at "cmdAddChild_Click" in the userform code. I haven't tried adding node images after a node has been created, it might fail at that point perhaps?

I am trying to figure out how to use the demo. I have a simple access db that uploads files, trying to build something similar to Explorer structure or sharepoint. The ability to upload files in a tree structure, view the files, download, delete, etc. with the ouptu showing a interactive tree structure. How do I go about doing that with your demo? Thanks.

Hi Kronos,

The demo shows you the technicalities behind how to implement this treeview into an Access project: What are the steps you need to take to add the treeview to the VBA project, how you populate the treeview, and how do you show the tree on a form.
How exactly you would integrate it into your own project is up to you of course.

Hi Jan,
first of all i'd like to thank you for the effort you do in Treeview For Access module
however, if you please create a video about how to add the tree view to a new form in a new database with a steps of all nessesaries needed to make it run
as you know not all users are profissional enouph to dive deep into the code
thank you

Hi Yasser,

It is all explained quite extensively in the Access download, click the "How do I...?" button on the main form.

If your question is not directly related to this web page, but rather a more general "How do I do this" Excel question, then I advise you to ask your question here: www.eileenslounge.com.
