SYMPTOMS

The Valid event of a combo box object in a page frame fires before the Gotfocus event after accessing the combo box multiple times.

CAUSE

As shown in the example below, do not use any object on the page frame to set the focus to another page. Move the "Click me - back to page 1" button to the form level instead.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Steps to Reproduce Behavior

Create a form and add a two page Page frame. In the second page of the page frame, add a command button and then add a combo box object. (In that order.)

Set the following properties and events of the command button:

      Caption ="Click me - Back to page 1"
      Click= thisform.pageframe1.activepage=1

Set the following properties and events of the combo box:

      RowSource = 1,2,3,4,5
      RowSourceType=1-value
      Valid event= =Messagebox("Valid Fired")
      GotFocus event= =Messagebox("GotFocus Fired")

Run the form.

Click Page two of the page frame. Next, click the drop-down combo box and select any number. Note that the GotFocus event fires before the Valid event. Click the "Click me - Back to Page 1" button on the second page. Now, repeat these steps noting that the Valid event fires before the GotFocus event this time.
