I tried all but the issue is the first loaded validation only works, for another company the model validation only not goes in debug. please suggest what to do.

  It is hard to achieve but you can set property of validation attribute class that decide to perform validation or not. Also you can use Session inside the validation attribute to check perform validation or not.

Yes Gaurav. Its really good idea beacuse the Data Annotation validators is that they enable us to perform validation simply by adding one or more attributes like the Required or String Length attribute – on the class property. this will help to reduce code size as well as code reusability. Also MVC, EF and WCF inbuilt support for this.
