Hello;

I have a browser-enabled form which has a repeating table in it.

My problem is: how can i validate that at least one of the checkboxes  is selected and prevent the form to be submitted if none is selected.

I'd appreciate any help.Thank you

I had a different solution.

In changed event of the checkbox i controlled if the value is true, then set a value in the xml which i control when submitting the form.It works fine.Remember to set "always"  ıf the postback options of the checkbox

 Please check if this helps to you

var isValid  ="0";

$("[id$='tbl']  :checked").each(function () {
                isValid = "1";
                return true;
            });

            if (isValid == "0") {
                alert('Please select at least one  Value');
                return false;
            }

<table id ="tbl" >

<tr><td>chk1<td></tr>

<tr><td>chk2<td></tr>

</table>

* You could do this with jScript - it might even be easier than the following method, which doesn't require rules.

When I've had multiple check boxes - and at least one must be checked, I've used a counter field.

So you have 3 chk box fields my: chkBox1, my: chkBox2, my: chkBox3. You also create a field to store a 'counter' my:chkCount

On each chkBox field I put two rules.

if chkBox = true then my:chkCount = my:chkCount + 1

if chkBox = false then my:chkCount = my:chkCount - 1

This means that whenever at least ONE check box is ticked, my:chkCount will be greater than 0 and if none are ticked then my:chkCount = 0

Then on  each chkBox validation rules I say that my:chkCount must be > 0. So all chkBoxes now show up outlined in Red until at least one checked.

I currently have Infopath uninstalled - if you still don't understand, I'll be back tomorrow with an example to attach.

Eureka!  (which is also a great show on scfi;)

Anyway, thank you thank you!

I went about it a little different but you spurred the idea for me with the chkCount hidden field.  What I did different was to due my validation on the Submit button to check to see if chkCount > 0 and that worked perfectly:)

 Thank you,
