Passing Parameter

Can someone tell me how to pass a parameter from a submit button to an action controller based on a selection from a dropdownlist.

can you give an example of what you are trying to achieve?

I think the cleanest way of doing this is to set the value of a hidden field. Not sure why you can’t deduce that param from the dropdownlist, though.

for example i have a dropdownlist with different months say i select January i want that value to be passed to the action controller when i click the submit button

You do not need to touch the submit button for that. It’ll be in $_REQUEST[<fieldnamegoeshere>].
