How is the best way to valid an entry ?

[Edmilson]

Hi,

I´d like to know if there is a pattern to valid some input controls.

For example, I´d like to know which is the best way to valid an
textbox... should I use Javascript ? RequiredFieldValidator? or another one
?
By now, I´d like to know how to valid a textbox that need to have at
least 3 characters...

tks
Ed

I'd suggest using the regular expression validator control.
