Step 1:Add the Contact Selector control to InfoPath – this only has to be done once within InfoPath, then it will be available for future forms.
1. From the Controls task pane, click on “Add or Remove Custom Controls…” then click Add.
2. Select “ActiveX Control” then click Next.
3. Locate “Contact Selector” in the list, select it, then click Next.
4. Ensure “Don’t install a .cab file” is selected, click Next.
5. Set the Binding Property to “Value”, click Next.
6. In the drop-down menu for field or group type, select “Field or Group (any data type)” then click Finish.
7. Click Close, click OK.

Step 2: Add a data connection – this must be done for each new form created.
There is some preliminary work here, first you have to create an XML file and save it. Open notepad and paste: <Context siteUrl="http://<your site url>“/>. Save the file as Context.xml. This same file can be used each time you create a new data connection of this type.

1. In InfoPath click Tools>Data Connections, then click the Add button.
2. Select “Create a ne connection to:” and “Receive data”, click Next.
3. Select “XML Document” and click Next.
4. Browse to the Context.xml file you created in notepad, click Next.
5. “Include the data as a resource file in the form template or template part” should be selected, click Next.
6. Leave the connection named “Context” and automatically retrieve the data when the form is opened, click Finish.

Step 3: Add the control to the form.
1. Drag and drop the control to the desired location on the form.
2. Go to the Data Source task panel.
3. Modify the data source so that the group that is created by the new control is exactly like the data source pictured. The “Person” group is a repeating group, the field names are case sensitive and must be exactly as shown below.

The control on the form that can be used to lookup users in Active Directory. Which is pretty nice if the DisplayName and Account ID are all the information that is needed. Here’s how to get more:

Step 4: Add your rules.

1. While in the Data Source task pane, create a field in the main data source (but not in your Contact Selector group) and name it something meaningful. I use HiddenAccountName to keep it distinct from the field in the Contact Selector group.
2. Click the drop-down menu on your data field in the data source, click “Properties”, then click the function button to set the default data.
3. Click “Insert Field or Group…”
4. Select the AccountId field from your contact selector group, then click OK on each window until the Field or Group Properties is showing(2 times).

5. Click the Rules and Merge tab, click Add.
6. Don’t set any conditions, this rule always applies, click Add Action.
7. Select “Set a field’s value” from the drop down.
8. Click the data source button next to the “Field” field.
9. Select the data source you wish to use for the lookup in the drop-down menu. *Be sure you don’t re-use the connection for the current user data if you have one in this form.
10. Expand the query fields and sub-groups, then select “Account Name”, click OK.

11. Click the function button next to the “Value” field, then click Insert Field or Group.
12. Select the current field you created in step 1 above, click OK until all windows are closed (3 times).
13. In the data source pane, use the drop-down menu to select the data source that you will use to look up another user’s profile information.
14. Expand the query fields and all sub groups until the field AccountName is visible. Click the drop-down menu on the AccountName field, then click properties.
15. Click on the Rules and Merge tab, then click Add.
16. Do not set any conditions, this rule will always apply. Click Add Action.
17. Select “Query using a data connection” from the drop-down menu.
18. Select the data connection you wish to use for the lookup from the drop-down menu (it should be the same as the data source listed in the task pane), then click OK.
19. Click Add Action.
20. Select “Set a field’s value” from the drop-down.
21. Click on the data source button next to the “Field” field.
22. Ensure you change the data source to “Main” and select the field you wish to auto-populate, then click OK.
23. Select the function button next to the “Value” field, then click Insert Field or Group.
24. Expand the data fields group and all sub-groups, select “Value”, click Filter Data, then click Add.
25. Where the “Value” field is defaulted, click the drop-down and select “Select a field or group…”
26. Select the “Name” field under “Property Values”, click OK.
27. In the third field, click the drop-down and select “Type Text”.
28. Type the property from the user profile that you wish to enter in the field, then click OK until you are back to the “Rule” window (5 times).

Repeat steps 19 through 28 for all fields that you wish to have auto-populate with the other user’s data. It is important that “Query using a data connection” remain the first action. If it is not the first action, highlight that action and move it up until it is the first.

29. Click OK on all windows until you are back to your form.

Now you have a contact selector that allows a user to look up another user in AD and have their profile properties auto-populate fields on the form.
