How to make Custom View Engine in NopCommerce 4.3?

It seems Andrey M. and team are very lazy to make a complete documentation. I am not able to override view (with another model passed to it - an extended one) for a week. I need to do this in plugin and use my own theme for that.

Hi,

I am also facing same issue, could you please share your solution, how you did this.

I am not able to override view (with another model passed to it - an extended one)  .

Thanks

The solution is to learn MVC, .NET Core and NopCommerce. This is my solution in progress.

lol, thats funny.

I was able to do it, but its not a ideal way still works.
I created same partialview structure using same model, from that view i added jquery to call controller action which returns new view with my extended model. It still needs testing, but may be its useful for someone.

Yes, you are creative, but my task is to do all code in plugin+child theme, no changes in nop's original code.

I also did it in plugin only not in nopcommerce original code.

In plugin project goto-> Infrastructure -> ViewLocationExpander

public class ViewLocationExpander : IViewLocationExpander
    {
        private const string THEME_KEY = "nop.themename";
        public void PopulateValues(ViewLocationExpanderContext context)
        {
            if (context.AreaName?.Equals(AreaNames.Admin) ?? false)
                return;

            var themeContext = (IThemeContext)context.ActionContext.HttpContext.RequestServices.GetService(typeof(IThemeContext));
            context.Values[THEME_KEY] = themeContext.WorkingThemeName;
        }
    

        public IEnumerable<string> ExpandViewLocations(ViewLocationExpanderContext context, IEnumerable<string> viewLocations)
        {
            if (context.AreaName == "Admin")
            {
                viewLocations = new[] { $"/Plugins/PluginName/Areas/Admin/Views/{context.ControllerName}/{context.ViewName}.cshtml" }.Concat(viewLocations);
            }
            else
            {
                #region public side

                if (!context.Values.TryGetValue(THEME_KEY, out string theme)) return viewLocations;
                if (context.ViewName == "Viewname in NOP.web")
                {
                    viewLocations = new[] {
                            $"~/Plugins/PluginName/Themes/"+theme+"/Views/{path to viewname}",
                            $"~/Plugins/PluginName/Views/{path to viewname}"
                        }
                        .Concat(viewLocations);
                }

                #endregion
                //viewLocations = new[] { $"/Plugins/PluginName/Views/{context.ControllerName}/{context.ViewName}.cshtml" }.Concat(viewLocations);
            }

            return viewLocations;
        }
    }

The above code will redirect the view to plugin view. Now in plugin View use Jquery cal to plugin controller action and return new view with ur model.

After write above code you have to regiser viewLocationExpander in dbstartup file by below code

 /// <summary>
        /// Add and configure any of the middleware
        /// </summary>
        /// <param name="services">Collection of service descriptors</param>
        /// <param name="configuration">Configuration of the application</param>
        public void ConfigureServices(IServiceCollection services, IConfiguration configuration)
        {
            /// <summary>
            /// Represents object for the configuring plugin DB context on application startup
            /// </summary>
            services.Configure<RazorViewEngineOptions>(options =>
            {
                options.ViewLocationExpanders.Add(new ViewLocationExpander ());
            });
          
        }

Thanks, guys, I think JQuery is an idea!
