I have an editfield what uses a mask and I was wondering if I am
doing it correctly.
editfield1.mask="(###) ###-####"
Now when you enter data you have to do a Shift 9 to first enter the
"(", why is this? A mask should just be there to keep order as to
how the data is entered and have NO real connection to the
enduser's entry. Once the "(" is enter manually by the user the
rest of the mask works ok as you do not need to enter the ")" or
the "-" in the mask, only the first part of the mask you have to
enter the "(".
Now this may make some endusers upset as they may not know this and
it will cause a few bug reports to my software. So tell me, i'm I
doing it right or am I missing something?
Other than very basic stuff, I have not found the Mask property to be
flexible enough for my needs and telephone numbers have a lot of
possible variations.
Another approach is to validate the input after the field has lost
focus (such as tabbing to another field or clicking on a button), or
inline with the TextChange() event. This would allow you to accept
telephone numbers in a variety of formats including "(###) ###-####",
"(###) ###-#### x####", "###-###-####", "###.###.####", "##########"
or even *international* telephone number formats which almost never
follow the US format.
This is the type of approach that I took with the phpRegistration
example... it allows the user to input the data (even incorrectly)
but does not allow them to submit the data. Also, if the text
evaluates as valid but in a different format you can use the LostFocus
() event to enforce the telephone format you expect: 493.555.1039 =>
(493) 555-1039.
