Email marketing is one of those important strategies applications use for user acquisition. A typical newsletter email with embedded images and formatted text layouts is internally a HTML document rendered over the email body.

When we dig deeper, one can observe that these mails are generated by applying variable email content over a static template based HTML document; depending on the occasion and the data to be sent. NET framework internally uses Razor to render html views and data over layout files during a request. Applications developed using ASP. This cshtml file shall be rendered with the data we pass onto the Razor templating framework and fetch the plan HTML out of it.

The razor view file receives a model of type List and has the model iterated inside a table body as expected. Next we shall have a generic ITemplateService which helps us with the rendering and extracting stuff. We first create an interface ITemplateService that sets up the context for the implementation to occur. We make sure that the method GetTemplateHtmlAsStringAsync has a generic model type to be passed to it so that its not coupled with only a single type of model for usage.

First we being with setting up the httpContext on which the razor would work for the rendering. We make use of the IServiceProvider instance from the aspnetcore container by having it injected through the constructor. We pass the viewName as a parameter to the method into the razorViewEngine. FindView method which returns a ViewResult. The Razor View Engine searches for the matching views in all of the Views folder and returns a ViewResult object with information related to the fetched View.

If the specified view is not available to the engine, we return with no further processing. We pass the model passed to the method as an argument to the ViewDataDictonary class, which passes the model data to the RazorView for rendering. We create a ViewContext instance based on all the parameters which we have created in earlier steps as arguments. Observe that the StringWriter is also passed as a constructor parameter to the class which then holds on the rendered plain HTML content for our use.

On the Whole, our final implementation looks like below:. To use this service, We add this to the service collection as a scoped service to be able to inject an instance whenever required. Where the template resides under the Templates folder of Views folder, and the model data is received from the underlying data store. The code snippets used in this article are a part of a boilerplate solution called MailingNinja, which offers demonstrable implementation of PDF generation and Mailing with ASP.

Create a String writer stream and have a ViewContext be created basing on the actioncontext, viewdata and the stringwriter stream render the view over the context and have the output be written on the stringwriter return the string written and close the stream. Setting up the ActionContext: We make use of the IServiceProvider instance from the aspnetcore container by having it injected through the constructor.

Using Minimal APIs in ASP.NET Core Razor Pages

In ,. Later, in ASP. In ASP. NET Core MVC applications, the controller is responsible for accepting input, taking or orchestrating operations and returning a response.

Starting ultrasoft.solutions Core version , there are so far three types of WebApi responses that controller actions can return.

Return different types of content from ASP.NET Core MVC Action Result

First access the editor using that same id, then call getContent. Check out our previous article where we save to and load from our rich text editor using JavaScript and localStorage. After the TinyMCE editor is added to the initial example, the save and load functions are updated to access the editor content using these methods. In this case, you can use the setup option in the editor config. Again, check out our JavaScript localStorage example , towards the end, where we remove the load button and add the content on initialization. In this case, when calling getContent , you can pass in a parameter to indicate that, instead of returning HTML, you want the result in plaintext. Contact me on Twitter and let me know.

If you're still using ASP. NET 4 tutorial instead. This tutorial covers the end-to-end process of creating a brand new ASP. We will start from scratch and end with a fully functioning component. It assumes you have basic knowledge of ASP.

Each concept was introduced with. Net Core and both help simplify and clean up the way existing Razor Views are constructed. Even though TagHelpers and ViewComponents are their own independent implementation, they have some points in common.

I rebuilt the same web API using Express, Flask, and ASP.NET. Here's what I found.

Camilo Reyes demonstrates how to integrate the Create React app with. NET core to generate a scaffold which removes several dependencies. This tool generates the basic scaffold to start writing code and abstracts away many challenging dependencies. React tools like webpack and Babel are lumped into a single dependency. React developers can focus on the problem at hand, which lowers the bar necessary to build Single Page Apps.

ASP.NET Core - Serving Static Files

This post looks at the best ways to handle exceptions, validation and other invalid requests such as s in ASP. However, despite the similarities, when it comes to error handling, you almost certainly want to use a different approach for API errors. MVC actions are typically executed as a result of a user action in the browser so returning an error page to the browser is the correct approach. With an API, this is not generally the case.

    Does anyone know about radio here? We need a colleague who would tell briefly about the T2 transistor (it is not clear how to check rv = rv1). Hopefully there are radio amateurs here. If completely off topic, then I'm sorry. I have to write, I just don't see a way out. PS: if the spelling is not correct then also excuse me, I'm only 13 years old.
