I have two textboxes on a surveypage (among other controls like checkboxes ) and I want to check that if the first textbox is populated with a value, the second one is populated as well.
If not, the responses are not valid and the next button shouldn't take you to the next page. I tried to use the isvalid function on the Surveypage but it doesn't work.
I saw another much older post that the user was facing the same issue and it was listed as a bug. Was it resolved, should I keep trying to use the isValid on a surveypage?
If not, is it possible to set the required attribute of a textbox dynamically, according to the response of another textbox?
