Question

I have created RadioGroup using the code

var radios = new Ext.form.RadioGroup({
     columns    : 2,
       items: [
             {boxLabel: 'E-Mail', name: 'communication', inputValue: 1},
             {boxLabel: 'Nagios', name: 'communication', inputValue: 2}
        ]
   });

I want to check one of the radio button on some event. How to do it?
I tried using:

radios.setValue(true, false);

but it is not working.

Answer 1

radios.items.items should return you the radio buttons inside the radio group. You can then use the setValue() function on them to check or uncheck them.

radios.items.items[index].setValue(true/false);
