Populate Two Form Fields From Drop Down List

Using a Second Field From a Lookup List/Drop Down List Box

Let's expand a previous example drop down list example and suppose that we have account numbers associated with each shipping method and that these account numbers (for whatever reason) can change over time.

Therefore we want to capture the current account number in the widget shipping record. Here is how the combo box looks in operation:

Now I bet you want to know how I got the account number to jump from the drop down list over to the account field.

It is fairly easy - add an Event Procedure to the After Update event trigger of the combo box. Here are the lines of code that go into the procedure:

 

The only line that you actually have to type is the one starting with Me...  Note that Column(2) contains the account number in the combo box.  Combo boxes start counting fields at zero.  The actual fields are: Shipping_Method_ID; Shipping_Method; Account.
