I need to be able to scale a value that represents a rating before the RepositoryItemRatingControl shows it. For obscure reasons we're storing our ratings as an integer ranging from 0 to 50. I need to scale the rating down by a factor of 10, so that it matches 0 to 5 stars.
I have attached an example of how I thought it should work, but I can't get it to work. The Format EditValue is never called.
How can I scale the values before displaying them?
Thanks.
We have fixed the issue described in this ticket and will include the fix in our next maintenance update. To apply this solution before the official update, request a hotfix by clicking the corresponding link for product versions you require.
Note: Hotfixes may be unavailable for beta versions and updates that are about to be released.
We have added new RepositoryItemRatingControl.FirstItemValue and RepositoryItemRatingControl.ValueInterval properties. Set the first property to determine the first possible rating value. The second property is necessary to specify a rating value interval.

Hi,
I see that currently, there is no way to determine the minimum and maximum values. I will pass this behavior to our R&D team for investigation. We will update this thread once we have results.
In the meantime, you can accomplish your task by creating an unbound Integer column and populating it with the necessary values manually in the GridView.CustomUnboundColumnData event. Then, assign RepositoryItemRatingControl to this column and hide the original one.
