• BI{code} ?

  yes, that won't work in the current version, but you can do this instead: var allv = JSON.stringify($('#ParentCategory').parent().find(':checkbox').map(function(){ return $(this).attr('value'); }).get()); $('#ParentCategory').val(allv).change(); $('#ParentCategory').data('api').render($('#ParentCategory').data('o')); and use KeyContent instead of SelectableItem as shown in the demos

  • That works! So I am assuming the code is assigning the stringified json array to ParentCategory.

  • I'd like to ask more question regarding this, what if I want to do something on client side(js) on checkboxlist checked/unchecked, how should I implement this? And will the select all/clear action gets the same behavior or do I have to do extra coding to hook them up?

  • this is done on the client side, it's setting the value and calling api.render, also the change event is triggered
