ControlToValidate cannot be used that way. It indicates the one-and-only
control to be validated by this particular validation control.
Note that the validation controls all derive from the Label control. A
validation control is thus a smart label - one which will only be visible if
the validation has failed. As a result, you need one of these "labels" next
to each control to be validated.
Now, if you're trying to avoid dragging large numbers of validation
controls, you can try creating them at runtime. You can either create one
validation control per TextBox, or you could even create your own
ValidatedTextBox control which would have both the TextBox and the
corresponding validation controls in it. You would then be able to drag
ValidatedTextBox controls onto your form. You could even get fancier and add
a label in front of the TextBox, all in one control.
You might want to take a look at the following: Developing a Composite
Control
(
http://msdn.microsoft.com/library/de...-us/cpguide/ht
ml/cpcondevelopingcompositecontrols.asp). Composite controls can be very
easy to develop, since most of the work is done in the controls out of which
the composite is formed.
