I have a repeating table containing two elements

1) selection(CHECKBOX CONTROL)
2)category(expression box)

How shud i validate that atleast one check box is selected

Thanks is advance

Hi,

If you are verifying this validation while submittin a form. Then add below condition to the submit button.

if "All occerences of checkbox" is equal to "false" then disable/hide your submit button.

where should i give if "All occerences of checkbox" is equal to "false".

i want atleast one check box to be selected

The expression:

not(/my:myFields/my:repeatingGroup[my:checkedField = 'valueWhenChecked'])

(substituting the underlined parts of course and adjusting the path as necessary) will be TRUE when none of the checkboxes is checked, and FALSE when at least one is checked, so you can use that as an expression in conditional formatting (to hide the submit button) or in the validation dialog.

Actually what i want is i want to make the user select atleast one check box and that expression didnt work for this situation

I understand just fine what your requirement is and that expression should work.  Could you show me the expression you are trying to use?

not(/my:myFields/my:group[my:checkbx = "no"])

on data fields

Well, unless the checkboxes have a value of "no" when they are checked, I believe you should probably have a different value in those quotation marks.  (My guess is that it should be "yes".)

Hi again Jimmy,

With the following condition
not(/my:myFields/my:repeatingGroup[my:checkedField = 'valueWhenChecked'])

Does that dynamically apply to all of the Repeating rows of data for the check box field?
If you don't use the "not(/my....."  and turn the values around, would the condition still work?

How would if the not condition is true, you increment a variable. And on the submit check for a nonzero value .

Would that work?
I guess on initial entry you should reset the variable. Can a not db variable be used? And how?

The expression I provided applies to all checkboxes in a repeating section.  It will evaluate to TRUE when all the checkboxes are unchecked and will be FALSE when one or more is checked.
