Adding field level and page level validations on VBCS pages

Content

Hello All,

I am looking for adding field level and page level validations on VBCS Pages like below,

1. Validation on Text component - Social Security Number validation,

For example: a) SSN cannot be 999999999 OR 999-99-9999

                       b) Not allowed Character   "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"

                       c) Length of SSN 9

                       d) Only Numeric allowed "1234567890"

                       e) As soon user tabs out of text field by entering 123456789 then the field value should become 123-45-6789 and also perform the                             above validations and throw error if anything is wrong, also should not allow user to save the record.
