asp.net mvc - DateTime field and Html.TextBoxFor() helper. How to use it correctly?

Question

I have a DateTime field in my Model. If I try to use this field in a strong typed partial view this way

<%= Html.TextBoxFor(model => model.DataUdienza.ToString("dd/MM/yyyy"), new { style = "width: 120px" })  %>

I will get the following compilation error at runtime

System.InvalidOperationException : Templates can be used only with field access, property access, single-dimension array index, or single-parameter custom indexer expressions.

Anyway if I use it removing the formatting, ToString("dd/MM/yyyy"), everything works but the field is formatted using the time part which I dont need at all.

Where I am doing wrong? Which is the correct way to handle this?

thanks for helping!

EDIT

This is the property declaration in the model class

[Required]
[DisplayName("Data Udienza")]
[DataType(DataType.Date)]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
public DateTime DataUdienza { get; set; }
