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.

Example:

using System.Web.Mvc;

namespace MyCompany.MyPlugin
{
  public static class HtmlHelperExtensions
  {
    public static string MyExtensionMethod(this HtmlHelper helper, ...

And add @using MyCompany.MyPlugin; to your view. Usage @Html.MyExtensionMethod

 

Useful: PluginDev configuration.
