Hello,
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?
Thank you,
Konstantina

What you ought to do is use the /branch attribute instead. I.e., if the 1st textbox is not empty and the 2nd is empty, run the same surveypage again:
<survey mysurvey>
/ pages = [1=pg1; 2=pg2]
/ showpagenumbers = false
/ showbackbutton = false
</survey>
<surveypage pg1>
/ caption = "Page 1"
/ questions = [1=tb1; 2=tb2]
/ branch = [if (textbox.tb1.response!="" && textbox.tb2.response=="") surveypage.pg1]
</surveypage>
<surveypage pg2>
/ caption = "Page 2"
</surveypage>
<textbox tb1>
/ required = false
</textbox>
<textbox tb2>
/ required = false
</textbox>

Thank you very much David!
The thing is that I am reusing the same surveypage keeping all the textboxes and checkboxes the same while I am only changing a caption.
Mystructure is more like this:
<expt spelling_test>
/ blocks = [1=spelling]
</expt>
<block spelling>
/trials = [1-2=pg1;]
</block>
<surveypage pg1>
/ caption = "Page 1"
/ questions = [1=tb1; 2=tb2]
/ branch = [if (textbox.tb1.response!="" && textbox.tb2.response=="") surveypage.pg1]
</surveypage>
<surveypage pg2>
/ caption = "Page 2"
</surveypage>
<textbox tb1>
/ required = false
</textbox>
<textbox tb2>
/ required = false
</textbox>
When I apply the code suggested the textboxes are reset after the branching.
Is there anything you can suggest in order to prevent that?
Your help is much appreciated!
Thanks,
Konstantina

No, if you run the <surveypage>s via a <block> instead of a <survey>, there is no way to prevent them from resetting, I'm afraid.

Thanks Dave! Also, just to confirm- the isvalid attribute doesn't work with surveypages. Is that correct?

Yes, that is correct.
