Can a data annotation discover other annotations?
I would like to build an extended DisplayAttribute
annotation that can detect if the property has the required attribute on it. And, if so and a "* " in front of the name to show it is required.
Is this possible? I can't seem t开发者_C百科o figure out how to discover if other attributes are present within an attribute. Even if it is possible, will the Html.Label
helper recognize it? Or do I have to extend that as well?
Writing a custom Html.LabelFor
will be enough. You don't need to extend the DisplayAttribute
as you cannot access other attributes from within an attribute.
