Checked State

A common way to set(get) the state of an item is setItemValue(). The method sets value for an item and checks it (if appropriate).
Applied to all items.

dhxForm.setItemValue(name, value);

For checkbox and radio items you can also use 3 more methods:

// checking items
dhxForm.checkItem(name, value); // for radio buttons 2nd argument value should be passed
// unchecking items
dhxForm.uncheckItem(name, value);
// getting current state
var isChecked = dhxForm.isItemChecked(name, value); // returns true/false
