MVC HTMLHelper Error

While starting with MVC one of the most basic error encountered is the one where using reference is missed for HTMLHelper class.

Below is the example of typical error.

System.Web.Mvc.HtmlHelper has no applicable method named ‘TextBox’ but appears to have an extension method by that name. Extension methods cannot be dynamically dispatched. Consider casting the dynamic arguments or calling the extension method without the extension method syntax.

To resolve this error you need to make sure you have added the namespace reference for “System.Web.Mvc.Html” to your files.

Where all that name space reference should be:

1. Web.Config of your Area. “<add namespace=”System.Web.Mvc.Html” />”

2.  View Page. “<%@ Import Namespace=”System.Web.Mvc.Html” %>”

3. Controller. “using System.Web.Mvc.Html;”
