Check box validation error

Gangadhar Gowd

Hi,

We have checkbox group as

<input type="checkbox" name="labelcheckbox" value=" Marketing" class="custom">

<input type="checkbox" name="labelcheckbox" value=" Customer" class="custom">

<input type="checkbox" name="labelcheckbox" value=" Emp" class="custom">



added validation code as 

context.save.evolutionValidation('addField', $("input[name='labelcheckbox']") ,
{
required: true,
messages: { required: context.subjectRequiredText }
},

'#' + context.wrapperId + ' .right-lable-error .field-item-validation',null);
}

in 11.x code is working excellent where as in 12.x its only validating first check box and ignoring other check boxes.

    Hi  . Sorry for the troubles. There were some updates to validation support in 12.1 which could have impacted this. But to get a little more context, as these are checkbox inputs and not radio inputs, what is your expectation for how the required field validator should behave?

    Hi  ,

    As you can see above there are three checkboxes out of which the user should select at least one of them. 

    In 11.x it used to work but in 12.x the validation is only checking the first checkbox

    To be specific "The required filed Message" won't allow us to proceed even if we check the other two checkboxes, It only disappears when we check the first check box and then allows to proceed to submit

    Hi . Sorry for the delay.

    The old behavior to validate that a single checkbox within a list of checkboxes is checked relied upon the undefined and undocumented behavior of an underlying dependency. Instead, I'd recommend using the addCustomValidation method of the evolutionValidation jQuery Plugin.  

    I've attached a sample widget showing an adaptation of your above code with custom validation implemented:
