I have two different ways to use a DISABLED TextBoxFor, which is:

@Html.TextBoxFor(u => u.Visibilidade, new { disabled = "disabled", @readonly = "readonly" })

and

@Html.TextBoxFor(u => u.Visibilidade, new { disabled = "disabled" })

ie. using or not readonly property

What is the difference, considering that a disabled field will not be changed any way?

Thanks in advance

Usually you would use one or the other, not both.

Readonly allows users to focus on the textbox to copy text or trigger an event. Readonly fields will be posted with the form.

With a disabled field, users cannot give focus to the textbox and the field will NOT be posted with the form.

Which one you use depends on what you need to do with the field.

If you want to enable focus but don't want it posted, you can make it readonly, but override the name property.

@Html.TextBoxFor(u => u.Visibilidade, new { @readonly = "readonly", @Name = "" })
