If you are using MVC3 you can use underscores in your html attributes, they are converted to dashes

@Html.TextBox("UserName", null, new { data_foo = "bar", required = "" })

html result

<input data-foo="bar" id="UserName" name="UserName" required="" type="text" value="">

Second option. Use dictionary instead of anonymous object

@Html.TextBox("UserName", null, new Dictionary<string, object> { {"data-foo", "bar"}, {"required", ""} })
