问题
If some of my models have dynamic validation conditions (i.e. the string length can be minimum of 8 or 12 depending on a database value or some other dynamic value) is it impossible to use data annotation for validation?
From what I understand, the values of any parameter (example StringLength min/max value) have to be truly static. Are there alternatives for applications that have dynamic validation values?

Your pretty much stuck with writing your own custom validationattribute:
