TextBox Leave Event fires, but not every time

After a user enters data into a field, I need to populate other controls on
the form, based on the user entry. I have to use either Leave, Validating or
Validated, and I take it I can't use LostFocus because there is no selection
for that event in the dropdown list on the code page. What's happening is
that all 3 events mentioned above for the textbox control fire in the proper
order when the form is invoked, but don't fire the first time I tab or mouse
out of the textbox. After that, they fire on cue.

I am invoking a child form from an MDIForm. I have several controls on the
child form (Form1), but this concerns a textbox (TB0) with a TabIndex of 0.
I invoke the form from the MDIForm with the following code:

Form1= New Form1()
Form1.MdiParent = Me
Form1.PARENTFRM = Me
Form1.Show()

In a step-through, I see that the Leave Event for the TB0 fires when the
last line of the above code executes (not sure why Another TextBox on the
form with a coded Leave Event doesn't fire at this point, even if I set it's
TabIndex to 0, and TB0 to 1.) When the form opens, focus is on TB0. I enter
data, then tab or mouse out to another TextBox (TB1), whose TabIndex=1 and
CausesValidation=True. No Leave Event fires on TB0. However, when I
Shift-Tab or mouse back into TB0, then tab or mouse out again, the Leave
Event on TB0 does fire. The event will fire for as long as I have the form
open, but the only important instance (the first one) of the event is
skipped! I can't expect users to tab out of and back into a field, so I'm
pretty much stuck.

Help. Please.

Hi Jaydee,

You might want to try setting focus to a different control and then back
again to tb0 inside the form's load event, simulating the click out and
click back in.

Thank you Bernie, your suggestion pointed me in the right direction.
Switching the focus back and forth did work, but not in the form's load
event. I put it in the MDI form's menu click event, after the child form's
Show() event is called. That worked fine. Thanks a lot for your help.
