change DateTime validation process

[usr338]

Hi
How can write my code instead of generated code for validating datetime ?
I mean i want to change validation process, not writing new code on Form_CustomeValidate because it runs after generated form validation.

If you want to validate your data with your own code only, you can set the [Validation] in edit tag to "None". Then the value will be only validated by your code in "Form_CustomValidate"
