It sounds as though you're using the same view to do Create and Edit. If you are the solution is simple, don't do that.

Those are two separate operations that have differing validation requirements.

OR

You'r using separate views already and are using the same validation scheme for both. Don't. I can't tell you how separate that because you can do validation in multiple ways and you never said how your validation scheme is setup.

I'm also stucked in this problem of Remote validation. I think this is not good solution DAVE to create separate models for create and edit. if we implement Remote validation in create view for unique username and do not implement unique validation in Edit model. then user may put username in edit view which might be already exists in database so no validation is implemented that username will be saved to database

First, don't hijack a thread that's a year old. Start you're own thread by posting your own question. Go to the "quick answers" menu and click on "Ask a Question".

Second, if you think using separate models is bad, then go ahead and struggle with your problem yourself. The requirements for models in a create and an edit operation CAN be different, very different. So, yes, using separate models for those two operations is quite reasonable.

Lastly, you're going to have to describe what you mean by "Remote validation". "Remote" is a relative term with respect to a viewpoint, which you never described.

I just came across this and it is pretty rude to tell someone to struggle with problem if they don't do what you suggest. You can have the same view for a create/edit by using a partial view and it makes it simplified to have to change only one view when a field needs added or removed. Validation is set one place in an extend partial class and call a remote Json request passing in the additional fields that are unique will allow editing and still have the validation.

You might want to go back and re-read the ENTIRE thread, and who's is posting what. Your critique is falling flat.

My position still stands. The requirements for creating a new record are usually different from editing an entire record. For example, in my largest web site, I need five pieces of information to create a new core record. When editing that record, there's about can be upwards of 150 pieces of information that need to be validated before the record is updated.

Using the same validation scheme for both operations will fail the creation of the record because so much information is missing.
