How to clear the post data for a textbox in an ASP.NET MVC application?

Question

By default, a textbox rendered using <%= Html.TextBox("somefield")%> uses the value from the post data, e.g. if you have validation errors on your page, the value is retrieved from the posted data and used for the value attribute.

Now, in a few cases I want to be able to clear that value, in other words I want the textbox to be blank, I don't want MVC to get the value from the posted data and uses it for the value attribute, how can I do? How can I clear the post data?

Thanks

ModelState.Remove("key");

Answer 2

Remove the value from the model state, like this:

ViewData.ModelState.Remove("somefield");
