Am new to ASP.NET MVC 3.0. Request expert’s view on the below mentioned scenario.

I have a customer details page, where only Name is editable. There are 10 other customer properties that are non editable and displayed using SPAN. When user submits the page, I need to update only the Name.

If am using EF, I will have to load customer again, overwrite name and then save. Otherwise I will have to maintain customer model somewhere.

Anyone tried caching model (or viewmodel) using session id? Is it a good practice?

    You are almost thinking in right direction.

    If am using EF, I will have to load customer again, overwrite name and then save. Otherwise I will have to maintain customer model somewhere.

    In Update Method **Load Customer again and update name Only as required and then save

    **For 2 reasons

    1. The first and most important rule is ‘don’t trust user data’. and
    2. Concurrency and to avoid saving old data. See this example

    Instead of using Session, I will suggest to use Hidden Field for record LastUpdateDateTime and Customer ID which will be posted back in the model to retrieve record and verify LastUpdatedtime with database record
