Product Rating without review

[dappy2]

Is it possible to create a control that could just let people rate the products? I know most of the code looks for a review profile, but I think it would be good to allow people to rate products quickly without submitting a review.

I went through the ProductReviewForm and copied/pasted the parts that seemed relevant but I'm getting Object reference not set errors on the button click. The page loads and displays fine.

The display code is just the copied drop-down list from the ReviewForm.

This is what I have in code-behind:

Code: Select all
