Question

Does MVC 3 support Xml data? I have a model class with a field (call it ‘MyCustomersXml’), and I want to stuff it into a hidden field. The issue I’m having is that I get a 500 error when the user clicks a submit button. If the field is null, nothing happens.

I know ASP.Net does some type of validation by default to prevent html style content in control values, so my question is does MVC 3 also share this behavior? If so, how do I bypass this behavior to allow Xml in the postback?

Answer 1

You could decorate this field with the [AllowHtml] attribute:

[AllowHtml]
public string MyCustomersXml { get; set; }

Now the ASP.NET framework will no longer throw an exception when you try to POST dangerous characters such as < and > in this field.
