We generally fire a validation on sumbit click.
Is there any specific reason you want validation to fire as soon as list is populated?

With your Question/comments I understood that you want to fire the validation message when ever the ddl count is more than 1.

So what i can suggest is to fire the validation messages we generally use Page.Isvalid() and these can fire the messages too.

you can use these method whenever the method is executing or in you can place in the ddl item change event.

If none of the point's mentioned above doesn't helps to your question please elaborate your question with the scenario & requirements.
