Access the Kanban Column (a Team-Specific Field) for a Work Item

Question

Is there a way to programmatically access the \"Kanban Column\" for a WorkItem using the TFS 2012 API?

Using the Scrum 2.2 template, the history of a Bug or Product

Answer 1

If you are prepared to dig into the database you can mine this information out. I don't fully understand the modelling of the teams in TFS yet but first you need to work out which field id the team of interest is storing the Kanban state in as follows (TFS 2012):

---

 USE Tfs_DefaultCollection
 SELECT TOP(10)
        MarkerField + 1 as FieldId,* 
 FROM tbl_WorkItemTypeExtensions with(nolock) 
 JOIN tbl_projects on tbl_WorkItemTypeExtensions.ProjectId = tbl_projects.project_id
 WHERE tbl_projects.project_name LIKE '%ProjectName%

Then replace XXXXXXXX below with the FieldId discovered above

---

 SELECT TOP 1000 
        wid.Id, 
        wia.State, 
        wid.StringValue as Kanban, 
        wia.[Work Item Type], 
        wia.Title, 
        tn.Name as Iteration
 FROM tbl_WorkItemData wid with(nolock)
 JOIN WorkItemsAre wia on wia.ID = wid.Id
 JOIN TreeNodes tn on wia.IterationID = tn.ID
 WHERE FieldId = XXXXXXXX and RevisedDate = '9999-01-01 00:00:00.000'
 ORDER BY Id
