Would be greate if we could expose ValidateOn to FormItem's. That way we could put:

<FormItem ValidateOn="ValidationEvent.Change" />

Rather than needing to specify a template, which feels a little unnecessary. If the datatype for the FormItem uses a field that doesn't use ValidateOn, it can simply be ignored, but for things like strings, numbers etc this would be useful.

Also a top level ValidateOn in the TelerikForm component could be useful, so you can set it once for the form, then maybe override it more granularly.
