I've a problem hidden/showing controls with javascript.

In this example I want show or hidde the dropdownlist if radio button is checked, but I can't do it.

For other hand, where is the documentation of controls' functions in script section?

Hi Manolo,

On analyzing your code, you have used setVisible(false) for hide dropdownlist. This method is not available in our dropdownlist. Instead of using this, you can use the JQuery hide and show method to show/hide our dropdownlist while check the radiobuttons. Please find the code for same:



        function onRadSemanalChange(args) {

            if (args.isChecked)



        function onRadDiarioChange(args) {

            if (args.isChecked)





Also, we have modified your sample based on this and please refer to the following sample:

Where is the documentation of controls' functions in script section?
We have a documentation link to know about our controls properties, methods and events information.Please go through the following API link,


Please let us know if you have further query.
