Hi Shiv, Thanks for submitting such a informative article which is short and precise and hence easier to understand. Two limitations, however, occur to me here: 1) Performance: Since validation run on the object and not on the UI elements, think of complex screen which may contain lots of UI elements. In this case we will have to first copy the Ui values to object so that validation can run on it. This may impact the performance. 2) Security: Since the validation rules get copied to .config file in plain text this exposes the business rules and also make them alterable by people with not good intentions. Just want to have your opinion on this and any solutions you mar recommend to overcome them. Vishal
