Walkthrough: Make Basic Customizations to a Work Item Type

In this walkthrough, you will customize an existing work item type in the most common ways. You will learn about the tools used to customize work items types and the XML language that defines these types.

These customizations are illustrated in the following procedures:

Create a Team Project In this procedure, you create the team project that contains the work item types that you will work with in the subsequent procedures.
View a Work Item Type In this procedure, you display the form of an existing work item type.
Export a Work Item Type In this procedure, you export the definition of the work item type into an XML file.
Rename the Type In this procedure, you change the XML file that contains the work item type definition to change the name of the work item type from Task to Special Task.
Import Changes In this procedure, you import into Team Foundation Server the work item type that you changed in the previous procedure.
Add a Field In this procedure, you add a new field that is named Category, to an existing work item type.
Add Rules to a Field In this procedure, you add a rule that makes the new Category field a required field.
Create a Pick List In this procedure, you add a list of allowed values for the Category field. The new values will appear as choices in a work item that is created from the work item type.
Change the Workflow In this procedure, you add new states and transitions to the work item type.
Change the Form Layout In this procedure, you change the positioning of fields on the work item form.

Prerequisites

To complete the steps in these walkthroughs, you will need the following:

A copy of Visual Studio Team System, or a copy of Visual Studio that has Team Explorer installed and has a connection to Team Foundation Server. For more information, see How to: Connect to Team Foundation Server.

If you can establish a connection to a Team Foundation Server and have the appropriate permissions, you can make basic customizations to a work item type at a command prompt, batch file, or script file. To do this, you must either use the Visual Studio 2008 Command Prompt utility or set several environment variables in your current command prompt by using vsvars32 as described in the following example. For more information about joining a team project, see Walkthrough: Joining a Team Project.

To enable Team Foundation commands at a command prompt

Click Start, click All Programs, point to Microsoft Visual Studio 2008, point to Visual Studio Tools, and then click Visual Studio 2008 Command Prompt.

Alternatively, you can run vsvars32 in the Visual Studio installation path that is usually DriveLetter:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools.

Required Permissions

To perform this procedure, you must be a member of the Team Foundation Administrators group or a member of the Project Administrators group for the project. For more information, see Team Foundation Server Permissions.

Create a Team Project

To create a team project

Start Visual Studio.
Open Team Explorer by clicking View, and then clicking Team Explorer.
In Team Explorer, right-click the name of the Team Foundation Server to which you are connected, and then click New Team Project.
In the New Team Project on <Team Foundation Server name> dialog box, under What is the name of the team project?, type WITLab, and then click Next.
On the Select a Process Template page, under Which process template should be used to create the team project?, click MSF for Agile Software Development - <version number>, and then click Finish.
Creating the team project may take several minutes.
When the Team Project Created page is displayed, clear the Launch the Process Guidance box, and then click Close.
The new team project that is named "WITLab," is created and displayed in a node under your Team Foundation Server in Team Explorer.

View a Work Item Type

Prerequisite: You have completed Create a Team Project. The "WITLab" team project is available.

To view a work item type

Start Visual Studio and open Team Explorer.
In Team Explorer, expand the WITLab team project, and wait several seconds for its folders to load.
In the team project, right-click the Work Items node, point to Add Work Item, and then click Task.
A form that represents a new Task work item is displayed. Some of its fields contain default values. In this walkthrough, you will customize the Task work item type from which this work item was created.

Export a Work Item Type

Prerequisite: You have completed Create a Team Project. The "WITLab" team project is available.

To export a work item type

Open a Visual Studio command prompt.
At the command prompt, type the following and then press ENTER:
witexport /f "File Path\task.xml" /t "Team Foundation Server name" /p WITLab /n Task
This exports the Task work item type from the Team Foundation Server to an XML file. The following is displayed when the export operation finishes:
Work item type export complete.
(Optional) To view the XML definition for the Task work item type, type task.xml at the command prompt and then press ENTER.

Rename the Type

Prerequisite: You have completed the Export a Work Item Type procedure.

To rename the type

In Visual Studio, click File, and then click Open File.
This displays the Open File dialog box.

Under Look in, move to the location where you exported the file.

If you are modifying a work item type to customize a process template, move to the location where you downloaded the process template.

Note:
If you are running Windows Vista, you might not have access rights to certain folders. If you try to export the work item type to a location where you do not have access rights, the registry virtualization technology automatically redirects the exported file and saves it to the virtual store. For more information, see http://go.microsoft.com/fwlink/?LinkId=92325 and http://go.microsoft.com/fwlink/?LinkId=92323. To avoid this redirection, you can export the file to a location where you have access rights.

Note:
The allowed values in the drop always appear in alphabetical order regardless of the order of the LISTITEM elements in the XML file.

Change the Workflow

Prerequisite: You have completed the Create a Pick List procedure.

To change the workflow

Open the file that contains the Special Task work item type definition. To do this, in Visual Studio, click the tab labeled specialtask.xml.
Find the definition of the work item type’s workflow, in the <WORKFLOW> section of the XML file, as shown in the following XML:
```
<WORKFLOW>
  <STATES>
    <STATE value="Active">
      <FIELDS>
        <FIELD refname="Microsoft.VSTS.Common.ClosedDate">
          <EMPTY />
        </FIELD>
        <FIELD refname="Microsoft.VSTS.Common.ClosedBy">
...
```
Notice that only two states are defined, Active and Closed. The transitions between these states are also defined, in addition to an opening transition from the null state that is used when the work item is first created.

Add an Unapproved state to the type definition by inserting another <STATE> element. The new state is shown in bold text.

<WORKFLOW>
  <STATES>
    <STATE value="Unapproved">
    </STATE>
    <STATE value="Active">
      <FIELDS>
        <FIELD refname="Microsoft.VSTS.Common.ClosedDate">
          <EMPTY />
        </FIELD>
        <FIELD refname="Microsoft.VSTS.Common.ClosedBy">
...

Create a transition between the null state and the unapproved state. To do this, first find the section of the workflow definition for transitions. Then, insert the following XML shown in bold text. Because of this change, all new work items of this type will start in the Unapproved state with the default reason of New.

<TRANSITIONS>
  <TRANSITION from="" to="Unapproved">
    <REASONS>
      <DEFAULTREASON value="New" />
    </REASONS>
  </TRANSITION>
  <TRANSITION from="" to="Active">
    <REASONS>
      <DEFAULTREASON value="New" />
    </REASONS>
    <FIELDS>
      <FIELD refname="Microsoft.VSTS.Common.ActivatedBy">
        <COPY from="currentuser" />
      </FIELD>
      <FIELD refname="Microsoft.VSTS.Common.ActivatedDate">
        <COPY from="clock" />
      </FIELD>
      <FIELD refname="System.AssignedTo">
        <COPY from="currentuser" />
      </FIELD>
    </FIELDS>
  </TRANSITION>

Delete the transition to Active that is shown in the following XML in bold text. Do this because there can only be one opening transition, and you want to use an opening transition called "Ported," which you will define in the following step.

<TRANSITIONS>
  <TRANSITION from="" to="Unapproved">
    <REASONS>
      <DEFAULTREASON value="New" />
    </REASONS>
  </TRANSITION>
  <TRANSITION from="" to="Active">
    <REASONS>
      <DEFAULTREASON value="New" />
    </REASONS>
    <FIELDS>
      <FIELD refname="Microsoft.VSTS.Common.ActivatedBy">
        <COPY from="currentuser" />
      </FIELD>
      <FIELD refname="Microsoft.VSTS.Common.ActivatedDate">
        <COPY from="clock" />
      </FIELD>
      <FIELD refname="System.AssignedTo">
        <COPY from="currentuser" />
      </FIELD>
    </FIELDS>
  </TRANSITION>

Add a "Ported" reason for the opening transition by inserting the following XML shown in bold text. This lets users know whether the work item is new or was ported from another tracking system.

<TRANSITIONS>
  <TRANSITION from="" to="Unapproved">
    <REASONS>
      <DEFAULTREASON value="New" />
     <REASON value="Ported" />
    </REASONS>
  </TRANSITION>
...

Insert the following COPY rule that is shown in bold text. This rule defaults the Assigned To field to the user who created the work item, and it is to be evaluated only during the opening transition.

<TRANSITIONS>
  <TRANSITION from="" to="Unapproved">
    <REASONS>
      <DEFAULTREASON value="New" />
     <REASON value="Ported" />
    </REASONS>
    <FIELDS>
       <FIELD refname="System.AssignedTo">
         <COPY from="currentuser" />
       </FIELD>
    </FIELDS>
  </TRANSITION>
...

Note:
Inserting this rule under other <TRANSITION> or <STATE> elements will scope the rule to other Transitions or States.

Create a transition from the Unapproved state to the Active state by inserting the following XML, shown in bold text. Because of this change, when a Special Task is approved, it can undergo this transition.

<TRANSITIONS>
  <TRANSITION from="" to="Unapproved">
    <REASONS>
      <DEFAULTREASON value="New" />
     <REASON value="Ported" />
    </REASONS>
    <FIELDS>
       <FIELD refname="System.AssignedTo">
         <COPY from="currentuser" />
       </FIELD>
    </FIELDS>
  </TRANSITION>
  <TRANSITION from="Unapproved" to="Active">
    <REASONS>
      <DEFAULTREASON value="Approved" />
    </REASONS>
  </TRANSITION>
  <TRANSITION from="Active" to="Closed">
    <REASONS>
      <DEFAULTREASON value="Completed" />
      <REASON value="Deferred" />
      <REASON value="Obsolete" />
      <REASON value="Cut" />
    </REASONS>
...

Click Save to save changes to the XML file.
Import the changed Special Task work item type into Team Foundation Server. To do this, at a Visual Studio command prompt, type the following and then press ENTER:
witimport /f "File Path\specialtask.xml" /t "Team Foundation Server name" /p WITLab
This imports the specialtask work item type into the Team Foundation Server. The following is displayed when the import operation finishes:
Work item type import complete.
In Team Explorer, click Refresh to download the latest updates from the server.
These updates include the changes that you just imported. Wait several seconds until the Work Items node is loaded. Nodes that are still loading display the word working.
Create a new Special Task work item. To do this, right-click the Work Items node, point to Add Work Item, and then click Special Task.
This work item is created from the work item type that you changed and imported.
Notice that the initial State is now Unapproved and that the Reason defaults to New. Additionally, the Assigned To value defaults to your account name. Click the Reason field to see a list box that lists the reasons New and Ported.
In the Title field, type a title, and then click Save to save the work item. Wait until the save operation finishes, as indicated by Item(s) Saved on the status bar.
In the State field, select the Active value to approve the work item and transition it again. Notice that the Reason field defaults to Approved.
Click Save to save this transition.
Click Close to close the Special Task.

Change the Form Layout

Prerequisite: You have completed the Change the Workflow procedure.

To change the form layout

Find the <TabGroup> section of the XML file. Notice that there are <Tab> elements for Links and File Attachments in which each <Tab>element contains a <Control> element that renders the respective control.
```
<Tab Label="Links">
  <Control Type="LinksControl" />
</Tab>
<Tab Label="File Attachments">
  <Control Type="AttachmentsControl" />
</Tab>
```

Merge the two <Tab> elements into a single Links and Attachments <Tab> element that contains both controls by replacing the XML shown in the previous step with the new XML that follows.

<Tab Label="Links and Attachments">
  <Control Type="LinksControl" Label="Links" LabelPosition="Top" />
  <Control Type="AttachmentsControl" Label="Attachments" LabelPosition="Top" />
</Tab>

Find the section of the <FORM>, <Layout> definition that describes the Classification and Status groups.

<Group Label="Classification">
  <Column PercentWidth="100">
    <Control Type="WorkItemClassificationControl" FieldName="System.AreaPath" Label="Area" LabelPosition="Left" />
    <Control Type="WorkItemClassificationControl" FieldName="System.IterationPath" Label="Iteration" LabelPosition="Left" />
    <Control Type="FieldControl" FieldName="MyCompany.MyProcess.Category" Label="Category" LabelPosition="Left" />
  </Column>
</Group>

Note:
For best results, every Control or Group should display in a Column even if the Column spans the full width of the form. In turn, every Column should display in a Group even if the Group has no visible label or boundary.

Select the following lines shown in bold text, and then click Copy on the Edit menu to copy this content to the clipboard for later use.

  <Column PercentWidth="70">
