Page Validation Not happening

im using <asp:RequiredFieldValidator../> control to verify the text field entry and also using
pbok.Attributes.Add("onclick", "JavaScript:return(DateValidate());") to my submit button.

Actually i want to verify the date Field text box should not be empty and it should be a
valid date(custom format). So im using Javascript validation for Onclick event of submit Button.

this is not happens in my coding. why?

How to implement this task in my asp.net page?

How do you validate?

Did you do a

If Page.Isvalid then
'do something
else
'do something else
end if

Also make sure your button property causes validation.
