Hi Swapna,
In SSCE, if you click on the first dropdown in design, the events are given in the properties.
You can put your change method name in onSelect.
Let's say you put the method name handleChange in onSelect. In the custom code area, the method will be generated for you.
In the method implementation you can call the getSelectedKey to retrieve the selected value.
function handleChange(){
alert(DropdownBox0_c0c0.getSelectedKey());
}
You can also refer to the how to guide for UIElements
