How many textboxes & what are you validating against?

Norton,
I got the following tip from "Windows Forms Programming in C#" by Chris
Sells, from Addison Wesley.

Within your "Accept" button click handler (the "save" button) process each
control that CausesValidation to ensure that they are all valid...

Something like:

For Each control As control In Me.Controls
If control.CausesValidation Then
control.Focus()
If Not Me.Validate() Then
Me.DialogResult = DialogResult.None
Exit For
End If
End If
Next

Note this version does not validate controls nested within other container
controls, such as GroupBoxes, I would include the above in a recursive
subroutine.

The above code will cause the Validating event for each of your controls to
be raised, ensuring that all the controls get validated, before the dialog
is closed or the data is saved...

Hope this helps

Norton,

It sounds for me as a horse behind the car.

How can something be wrong in a textbox when you use correct the validating
event.
(Assuming you are not placing conflicting date in there by the program)

It will be executed as that control looses the focus.

What is it I miss?

The User doesn't /have/ to Enter and Leave every control before
clicking the button ... Devilish things, these mouses .. er .. mice? ;-)

Phill,

Now I understood you, in fact do you want to check if they are not empty?

However you can in my opinion for ever do (not tested)

sub ButtonClick event
textbox1_validating(textbox1,nothing)
textbox2_validating(textbox2,nothing)
etc.
end sub

As alternative for the already supplied options, while not knowing what
actions you take because of validationg errors.
