Hi Stuart,
I suggest to use the
RadToolTip's client side API in order to achieve the desired behavior. Basically the idea is to do the following:
- Hook up the submit event which should be the validating one (e.g button click)
- Check the visibility of the validator - if it is visible then there are validation errors
- If there are errors, execute a javascript function which references the RadToolTip and shows it.
You can find a working online demo which shows a very similar scenario here.
Best wishes,
