Keep a temporary variable in client side (Javascript). Set the last controlID in it that was in focus.

Now, use this temp variable whenever the validation failure occurs. In case of validation failure, set a bool flag to true.

Now, define onfocus on each control. In it, check if bool flag is true, if so, use the temp variable and get the last control that had focus. set it back. Done.

Try!

Solution 1

use Regular Expression Validator
and use it
ValidationExpression="(0[1-9]|[12][0-9]|3[01])[- /.](0[1-9]|1[012])[- /.](19|20)\d\d

hello,

Try set the SetFocusOnError attribute to true. If that doesn't work, check out this article.
