TextBoxFor Helper retains previous value even when model value is empty

Question

I have an MVC form for adding a simple entity. I am using TextBoxFor(model => model.FieldName) to create the input fields. I have a Save button and a Save and New button.

Answer 1

I would suggest using

ModelState.Clear();

instead of

ViewData = null;

since I find that much more clear what you are trying to do. Although both will accomplish what you're trying to do.
