So I was trying to get this to work with just using the Process Editor that comes with TFS Powertools. I was able to create the field that I wanted as well as the pick list.

What I couldn't do was define the PreferredType in the Controlfield name. My work around was to save the file to the server, export the wit, edit the xml in notepad++ save the wit file and then use the Process editor to import the Wit.

The good news is that the control works as expected when using Visual Studio and you have the control installed on your PC. What doesn't work is using the Web interface. I just get the dropdown and no multiselect.

Does the Web interface support the multivaluecontrol on TFS 2015 Update 3 ?

Any help would be greatly appreciated.

I tried a few of the other suggestions that I have found with using type and preferredtype designations. for the control. but that didn't help with the Web view.

If seems when I define the type as MultiValueControl it works in VS but in Web, when I open the form that contains the control I get: Cannot create work item control of type "MultiValueControl"

So it appears to be an issue only with using TFS web. What I am not sure about is if the workstation that is viewing the webpage also needs the controls installed. The zip file I downloaded contains the WitCustomControlSetup2015.msi file that I assume should be installed on any workstation that has Visual Studio 2015 and the CodePlexWitCustomControls.MultiValueControl.zip is the extension that gets installed into TFS web.

What am I missing here?

@PatDelaney, The latest version of the control refactored to support the new TFS "15". For TFS 2015 can you try to use the older version http://witcustomcontrols.codeplex.com/releases/view/620316. Let us know if this helps

Here is what I tested:
I replaced only the CodePlex.WitCustomControls.MultiValueContol.zip file on the App server. I did not change the MSI installer.

Version Result
1.3.2.4 Cannot create work item control of type “MultiValueControl”
1.3.2.3 Cannot create work item control of type “MultiValueControl”
1.3.2.2 Cannot create work item control of type “MultiValueControl”
1.3.2.1 It works!

So 2 questions:
Is it ok to run this older version of the Extension with the current version of the .msi file for Visual Studio?
What else can I do to help you figure out the issue?

Thanks

So to be clear what release does TFS "15" represent. I am fairly new to TFS so some of the things that are reference in the site are not clear.

Thanks for your help so far.

TFS "15" means TFS 2017 RC1

the control does not drop dwn with TFS 2017
Any idea what to do?
