InfoPath lookup field to SharePoint

I have a SharePoint 2010 list, EmployeeList. It has fields EmpNo and Department.
I have another list, Drivers in the same site and it also has EmpNo along with other informaiton.
I would like to create an InfoPath form to enter new drivers.
In it, I would like a drop-down for the DriverID field and a text box for Department. The driver id is the employee number. Therefore, the drop-down in DriverID should display all values from EmpNo in EmployeeList. In the form, as soon as I choose one employee number from the drop-down in DriverID, I want the Depatment text box to automatically populate with the corresponding department from EmployeeList.
How can I achieve this?

You need to research "cascading dropdowns" and filters.

Good examples at www.infopathdev.com

You will create a data connection to the drivers list

Set up 2 dropdowns
have the second dropdown use the driver list
But have a filter so that empid equals the field of the first dropdown.

When you get to infopathdev.com search on cascading dropdowns, or you can on any search engine.

I am on my phone at the moment but there are several good tutorials.

Hello,

I don't know why you don't want to click a link to another web site, but if you insist:

In the InfoPath form, create a new data connection to receive data and point it to the Employee list. Make sure to include the fields for EmployeeID and Department. Give it the name EmployeeList

In your main data source, you need a field for DriverID and one for Department.

Drag both fields to the form.

Change the DriverID control to be a dropdown. Edit the control properties and click "Look up values from an external data source".

In the Data Source field, select the EmplyeeList data connection.
Set both the Value and the Display name to be EmployeeID and close the dialog.

Create an action rule on the DriverID field. The rule should fire whenever the field is changed.

Create an action to set another field's value.

Select the Department field in the Main data source as the field to be changed.

In the Value box click the formula button. In the next dialog click "Insert Field or Group".

Select the EmployeeList data source, open the Data Fields node and click on "Department" and then click the button "Filter Data". In the next dialog click "Add".

In the Filter dialog, set the first value field to EmployeeID of the EmployeeList data source: click "Select field or group", select the data source EmployeeList, open the Data Fields node and select the field EmployeeID.

Set the comparison operator to "is equal to".

Set the second value field to DriverID of the Main data source: click "Select field or group", select the Main data source and select the field DriverID.

Click OK on all the dialogs.

cheers, teylyn

teylyn, I didn't want to click on the link because it leads me nowhere - the contents are unrelated to what I am looking for. Your solution - your detailed solution is exactly what I was looking for - Thank you!
