how to format date with Html.TextBoxFor helper ?

There are a number of ways you could do this.

You could create a DateTime editor template, which will mean that all dates are edited in the same way.

Have a look at the following which describes how to implement a jquery date picker.

I was trying to use the below syntax's.But the formatting is not working .  
 
<%= Html.TextBoxFor(model => model.ExpirationDate, String.Format("{0:MM/dd/yyyy}",
Model.ExpirationDate))%>

Thanks
