I am developing plugin for customize vendor detail from admin dashboard.
For that I have overrided Edit action and view(Edit.cshtml, _CreateOrUpdate.cshtml) accordingly.
But I facing below issue when opening that page,
Unable to access htmlextensions like
1. Html.SetActiveMenuItemSystemName("Vendors");
2. @Html.DeleteConfirmation("vendor-delete")
below are the error,
CS1061: 'System.Web.Mvc.HtmlHelper<viewmodel>' does not contain a definition for 'DeleteConfirmation' and no extension method 'DeleteConfirmation' accepting a first argument of type 'System.Web.Mvc.HtmlHelper<viewmodel>' could be found (are you missing a using directive or an assembly reference?)
Please let me know, how to access HtmlExtensions which are defined in Nop.Web.Framework.
Thanks in advance!
