ModelState.IsValid always false

Put this line above ModelState condition and check the values you getting for variable errors.

var errors = ModelState.Values.SelectMany(v => v.Errors);

A potentially dangerous Request.Form value was detected from the client

You can see this error everytime when you submit HTML code to the server. To avoid this set validateRequest="false" in the page and in .net 4 you need to add this <httpRuntime requestValidationMode="2.0" /> to the web.config file. Thanks Lasa

Invalid anonymous type member declarator MVC

I got this error message when i use  @data-group in ActionLink.

@Html.ActionLink(cardCategory.Name, "Index", new { controller = "Home" }, new { @class = "btn btn-default btn-lg btn-filter", @data-group = "C" })

Use an underscore _ - the Razor engine is smart enough to translate that to a data- attribute.
