I have a radiobutton list that has a SelectedIndexChanged attached to it. So a user changes the radiobutton and SelectedIndexChanged is triggere.

Let's say I manually change the radiobutton list value in page_load, what would I need to do so that it automatically fires SelectedIndexChanged? Basically emulate the user functionality, but from codebehind.

Currently, the eventhandler is not triggered when I change the value from codebehind.

Thanks.
