asp.net - RequiredFieldValidator have to click twice

Question

I have run into the same problem as described here.

Only the question is marked as answered with only an explanation as to why you may have to click twice when using a RequiredFieldValidator on input fields - once as the blur of a textbox(for example) will correct the validation and then again to actually post the form.

I don't want to have to click a button twice! Does anyone know a solution or workaround to this?

Answer 1

You could add EnableClientScript=false to the validator.

That prevents the client-side validation, so you will always get a postback (which may not exactly be what you want, though). The validation will still be done, just server-side.

Be sure to wrap the button-click logic in a if (Page.IsValid) { ... }, to check the status of the validators.
