I am trying to make some logic to use view component within asp.net core razor pages.
Following here https://learn.microsoft.com/en-us/aspnet/core/mvc/views/view-components and my test project at https://github.com/azizkazdal/aspnetcorerazorpages/tree/master/ViewComponent
can anyone tell me what am I doing wrong?
Made a simple logic but could not worked it
I have not got any issue just was taking not content from view component.
then I wrote aspnet github channel and they send me below answer
Component.InvokeAsync returns an IHtmlContent: https://github.com/aspnet/Mvc/blob/dev/src/Microsoft.AspNetCore.Mvc.ViewFeatures/IViewComponentHelper.cs#L26. The returned value needs to be written to the output, like the second instance, for the view component's content to appear in the output.
So I changed the code like as below
#await Component.InvokeAsync("DeleteModal", new { name = "Default", item = Model.ViewModel.DeleteModalViewModel })
I was coding Component.Invoke methods as below
#{
#await Component.InvokeAsync("DeleteModal", new { name = "Default", item = Model.ViewModel.DeleteModalViewModel })
}
and this worked fine.

I have a razor page in my project. This page catches encrypted Ids and sends to a razor component which is working dynamically as parameters. The problem is that one of the methods of the razor components must be called from the razor page. Is it possible or is there any other way to resolve the issue?
I'm tried to create a service for the methods of the component. But I was not able to pass the parameters in the service to the component and control the right divisions at the right time with two way binding.
I hope the below example helps. We pass encryptedIds to the ComponentTwo component method in this example.
<ComponentTwo #ref="_component" />
<Button Color="ButtonColor.Danger" #onclick="SendEncryptedIds"> Send </Button>
#code {
private ComponentTwo _component;
private async Task SendEncryptedIds()
{
var encryptedtIds = .... get the ids ....
await _component.SendDataAsync(encryptedtIds);
}
}
On my MVC project I have to incorporate 40 static pages.
I want these pages to use the Layout page.
What is the best way to do that?
I know this question was asked before but I didn't find any good answer.
Any advise?
I don't relly know ASP, but I try to give a generic answer.
So I think if you have a lot of similar static pages, somehow you could make a controller action that handles all these pages. For example the action gets the name of the page as a path variable in the URL, and return the view according to that.
But if that is not possible in the language you are using, you can just make simple separate actions for these pages. Maybe you could group the related ones into the same controller, so you would have a few controllers that handle these pages, and they are not stuffed in one controller.
Basically the solution is very simple, you have to create views for you static HTML (cshtml), then you should add a Route to your Route.Config like this:
routes.MapRoute(
"OrdeForm",
"OrderForm/{file}",
new { controller = "MyController", action = "Page", file} = "" }
);
Where "File" is a dynamic parameter that gets the View name from the URL and renders the right View.
The global controller should be something like this:
public class OrderFormController : Controller
{
public ActionResult Index(string file)
{
return View(file);
}
}
That works perfectly!
Thank you #Erik Philips for the excellant answer!
I have been researching dynamic content for MVC views and partial views but have not successfully found an architecture to fit my needs.
Basically I am required to create a landing page based on parameters pass by the URL.
For basics
http://mydns.com/myconroller/myview/?landingpage=Param1
The controller will need to find the HTML that will be used to create the view.
The view is going to be different based on the landing page.
(for the sake of the question, I am using landingpage as an example)
My goal is to be able to deploy a Landing page and based on the URL use that HTML Landing page in the view based on the landingpage parameter that is passed.
There are other views that are working currently in the controller. I am trying to add functionality to be able to add a new one time page without having to recompile.
I have searched through various ideas on how to load dynamic views but cannot seem to find a solution that fits this need based on what I have read.
I can possibly RedirectToAction but I am still in the dark on where to deploy and I am getting several problems with Razor as it is not in the shared directory and then I am stuck with deployment issues as I want to organize the landing pages differently than I am organizing the views.
Solution:
I decided to take a different approach and use the ContentResult Action in the controller. I still have the Main View and I use the HTML extensions to render the HTML pages that I have deployed in my customer's directory.
#{
Html.RenderAction("LandingPageContent", "Controller", Model);
}
Then in the controller I load the HTML directly and return the ContentResult
public ContentResult LandingPageContent(object model, FormCollection collection)
{
MySRCHelper helper = new MySRCHelper();
ContentVariables variables = helper.getContentSRC(model.EntryCode);
model.ContentSRC = variables.LandingPageSRC;
return Content(System.IO.File.ReadAllText(Server.MapPath(model.ContentSRC)));
}
I can then configure the path to the raw HTML file to be used and it will be loaded into the View. The View can then house all of the paths to load jQuery, CSS and other necessary javascript to integrate with the raw HTML and allow me to deploy the HTML files into any directory structure that I want. The configuration XML file allows me to find XML elements and use those values for any HTML that I am looking for, like a welcome and thank you page. The helper object will open the XML and find the configuration based on the parameters passed to the View.
<ContentLandingItem entrycode="1" customerID="Cutomer1">
<ContentLandingPageSRC>~/Customers/Customer1/Customer1Landing.htm</ContentLandingPageSRC>
<ContentThankyouSRC>~/Content/Default/GenericThankyou.htm</ContentThankyouSRC>
</ContentLandingItem>
<ContentLandingItem entrycode="2" customerID="Cutomer2">
<ContentLandingPageSRC>~/Customers/Customer2/Customer2Landing.htm</ContentLandingPageSRC>
<ContentThankyouSRC>~/Customers/Customer2/Customer2Thankyou.htm</ContentThankyouSRC>
</ContentLandingItem>
The view still performs its duties and works independently on it own letting the raw HTML decorate the View. The model is still intact and can be used as I wish. The FormCollection is there in case a form submit posts the values to the view and provides some things that I omitted from this question as it did not pertain to this subject.
I don't want to answer my own question and I found the pieces that helped me on another site, so I am putting what I did here in case anyone needs this functionality.
This sounds like using the you can inherit from the virtual path provider view engine and decide based on the URL parameters (or other) which view to return. Some example that you can adjust to your needs:
public class CustomViewEngine : VirtualPathProviderViewEngine
{
public MyViewEngine()
{
this.ViewLocationFormats = new string[] { "~/Views/{1}/{2}.mytheme ", "~/Views/Shared/{2}.mytheme" };
this.PartialViewLocationFormats = new string[] { "~/Views/{1}/{2}.mytheme ", "~/Views/Shared/{2}. mytheme " };
}
protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath)
{
var physicalpath = controllerContext.HttpContext.Server.MapPath(partialPath);
return new RazorView(controllerContext, physicalpath);
}
protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath)
{
var physicalpath = controllerContext.HttpContext.Server.MapPath(viewPath);
return new RazorView(controllerContext, physicalpath);
}
}
In there you can return a RazorView or WebFormView and set your desired path for the view to use.
I just switched from Umbraco 4 to Umbraco 5 and it seems like a lot has changed.
So what i basically want is a possibility to add a alternative template to my document-types.
The fall back template shall return the content as JSON.
Why, you say? I want to create an API-like way of accessing the Umbraco data from my mobile devices.
WebAPI (http://cultiv.nl/blog/2012/4/22/exposing-umbraco-5-content-through-the-aspnet-web-api/)
I have thought about using WebAPI from asp.net MVC 4, but the project is really just a proof of concept and i don't want to code each endpoint.
So i found a som guys that did a package for Umbraco 4 that actually does this and renders the content of #currentPage as Json. The template is hit by adding "/JSON" to the end of the url. Unfortunetly this uses xslt, which ihas been removed from Ubraco 5.1 (Good thing).
So. I bet it's simple to create a partial, a macro or a partial macro that does this and add it to a template. But is just cant figure out where to start.
Any help with that? What I'm looking for is a step guide on what steps to take, to make the setup. Rendering the stuff ad json in C# i can handle.
It's the integration into Umbraci I lack.
Hoe u can help.
The alternative templating works exactly like in v4: Just add the name of the template at the end of the url: yoururl/json
Then add a new razor view to the templates named "json" with the following code:
#inherits RenderViewPage
#using System.Web.Mvc.Html;
#using Umbraco.Cms.Web;
#{
Layout = "";
}
{
#foreach (var attribute in Model.Attributes)
{
string.Format("\"{0}\": \"{1}\"", attribute.AttributeDefinition.Alias, attribute.DynamicValue);
}
}
This code can be used as a starting point without using the web api or own controllers.
Don't forget to allow the tempplate on all document types

I have Razor woking with Nancy, but can't figure out how to make the view see the model.
I am rending the model with this code (where t is the model instance).
return View[ "views/addshortcut.cshtml", t ];
How can I make the Razor see t?
The model is there, just start using it. If you are talking about intellisense then you can use the #inherit statement in razor.. something like
#inherits Nancy.ViewEngines.Razor.NancyRazorViewBase<YourNameSpace.YourModel>
