Customize TFS workitem screen

Question

This is related to TFS2010 I have the following requirment:

Multiple tasks can be associated with a user story when a user story is closed using the VSTS UI, I need to check if all the associated tasks are closed as well.

My Question:

Is it possible to bind a validation function to workitem UI?

will witadmin be of use in this case?

Answer 1

witadmin is used to administer your work item templates, not for editing them.

Your requirement cannot be fulfilled with a simple work item template. I think you have to create a query to select all tasks that are not closed but have a closed user story.

Another way is to create a TFS addon. A similar task has beed described here.
