I am using MVC 3 with ASP.NET. I have a dropdown box and getting it populated from database. I am using validation on the View. If it fails the validation, I am displaying the same view with errors being caught in ViewDate.ModelState.AddModelError.

I am checking for the ViewData.Modelstate.IsValid property if true then execute the code else display the errors in the view.

It is diplaying the errors in the page, but the selected value in the drop down is getting reset when validation fails.

How do I make sure the seleceted drop down does not change when validation fails?

    In the action that handles the form submission and validation, make sure you set the properties on your model object from the form before rendering the form view.

    For example, in this question you can see how the Dinner object parameter in the Create action is reused when the View() is returned.
