RequiredFieldValidator doesn't show error message and missing __postback function

[John Sutter]

I have a webpage which has a few asp:textbox's and an asp:button. I also
have a few RequiredFieldValidators for these text boxes. When I click on
the button while the textboxes are empty, I don't see any error messages
from the validators. I noticed the __doPostBack function is also missing
along with the two args in the source.

I thought a button adds this function. When I changed a textbox to
autopostback, the function appeared. But I don't want to autopostback and
the error messages still don't show up.

I have display set to dynamic, enabled is true and enableclientscript is
true.
Any clues?

Make sure on your Postback that:

Post.IsValid = true

you could place this in Page_Load method

From what you have described, the system doesn't think Client-side
validation needs to be setup for the submit button.

There are two possibilities
1. The button has CausesValidation=false. This omits the call to
Page_ClientValidate() and thus prevents client-side validation.
2. The page thinks the browser isn't IE. The ClientTarget on the page may
not be blank. It may reflect something like "Downlevel". Client-side
validation requires detection of IE.
