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(){



You can also refer to the how to guide for UIElements

Can you please also post the best practices way to reload a drop down list box?  Currently the documentation above does not indicate how to refresh or reload the drop down list box.  As a work around you can re-add it to the form and then draw the form again but this loads the entire form.  Suggestions and recommendations for loading only a single drop down list box in SSCE is appreciated.

Hi Sam,

In 15.1 FP1 You can use the following method.

1. DropdownBox1_c0c0.updateItems();

2. If you wanted to pass a parameter to the Query template of dropdown you can use it like this

DropdownBox1_c0c0.updateItems({"Param.1" : key});
where key is the selectedkey value from the dropdown box
