-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0, 5.0a, 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

In a grid, focus leaves the text box control to go to the control you are
clicking even though the Valid method of the text box returns .F. or 0. However,
the focus remains unchanged in the text box control when you are tabbing out to
move to a different control.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.

MORE INFORMATION
================

Steps to Reproduce Behavior
---------------------------

1. Create a new form, named mytest.

2. Add a one column grid to the form and two Command buttons.

3. In the Load event of the form, insert the following code:

        SET SAFETY OFF
        CREATE TABLE xyz (name C(10))
        INSERT INTO xyz VALUES ("test")

4. In the Valid method of the text box in the grid, place the following code:

        RETURN .F.

5. Save and run the form.

After you open the form, click Command button 1. The "Invalid input" message
appears and then the focus shifts from the text box in the grid to the Command
button. At the same time, the grid's text box also has a black border indicating
that it also has focus. At this point, if you press the Tab key, the focus moves
to the other command button. Apparently, the focus is no longer with the text
box even though the Valid method in the text box is returning false.
