hi all,
i want to validate my checkbox by using regular expression validation.
my requirement is,
1) my textbox should not allow starting letter as numeric and
it should not allow space in starting position....

thanks in advance,
prabhu.

...Are you talking about a validation in your code behind before you populate the Text property of a checkbox?? (Really, you would have to be, since a user can't physically manipulate a textbox's text property.)
