Dear All
I create new Html Helper Extension in my Plugin. But in view it not define
Compiler Error Message: CS1061: 'System.Web.Mvc.HtmlHelper<dynamic>' does not contain a definition for 'IsSelected' and no extension method 'IsSelected' accepting a first argument of type 'System.Web.Mvc.HtmlHelper<dynamic>' could be found (are you missing a using directive or an assembly reference?)
I add namespace into web.config, use @using NamespaceofHtmlHeplerExtendsion but still not been. So who can help me? Thanks alot.
