Asp.Net Mvc Hidden Field from Data Annotations

问题

I thought this would be a quick search on google but maybe I'm missing something. Is there a way, using Data Annotations, to set a ViewModel property to create a HiddenInput when the markup get rendered?

The only annotations I've found were to hide the property from the view entirely, I still want the property rendered but as a hidden input.

回答1:

This property:

[System.Web.Mvc.HiddenInput(DisplayValue = false)]
public int Id { get; set; }

will be rendered as i.e.

<input id="Id" name="Id" type="hidden" value="21" />

when using Html.EditorForModel() or Html.EditorFor(m => m.Id)
