form->combo of checkbox->multi-checked not find value



I have a form, it includes the combo of the checkbox, but when I checked one or more than one the checkbox, it can’t get the value.
I saw the sample of the combo. It has the event for multi-select of combo checkbox. It can get the multi-value.
event name: onCheck

but the event does not work in the form combo.

Could you help me which event or method can function it?

Many Thx.


Please, try to get the combo object at first:
var dhxCombo = myForm.getCombo(name);
so you can use:
after that
