With the accept attribute, we’ve restricted the uploader only for image files. After all, Create.cshtml should look like this. Now if you navigate the URL: /Image/Create, you could see a form with input controls corresponding to each model properties except for ImageFile. so we have to replace ImageName input controls with an image/file uploader corresponding to ImageFile property. Let’s open this project inside your browser, go to Debug > Start without Debugging. there are other action methods too, but not used in this project. In above controller, we have shown action methods required for demonstrating image upload. Now rest of the action methods could interact with the DB using this injected DbContext. We don’t have to create an instance of the context in each of the MVC controllers when the controller has a constructor parameter of the type ImageDbContext. This ImageController constructor has a parameter of the ImageDbContext (which is _context), ASP.NET Core will automatically inject the same class instance into the parameter as its value. Now let’s discuss how ASP.NET Core dependency injection helps this controller for interacting with DB. With the help of Scaffolding Mechanism, new controller will be created with necessary action methods for all CRUD Operations. ImageController will be created with ImageModel and ImageDbContext. right-click on Controllers folder Add > Controller, Select ‘MVC controller with views using Entity Framework’ template.

To update and retrieve images, let’s create an MVC controller. then execute following commands one by one.Īfter successful migration, As per the connection string, new Database ImageDB will be created with a new table Images corresponding to the model class.Ĭreate MVC Image Controller with CRUD Actions For that select project from solution explorer, then go to Tools > NuGet Package Manager > Package Manager Console. We’ve done everything for Database, Now let’s do the migration. How does this dependency injection work? that we can discuss once we create an MVC controller. Here, to set SQL Server as the DbProvider, UseSqlServer function is called with the above connection string. Here we’ve called the AddDbContext method, to inject an instance of PaymentDetailContext. Just update Startup class method ConfigureServices as shown below.

Now let me show you how to create an instance of DbContext with dependency injection. Let’s save the connection string in appsettings.json file. Location of Database: Connection string to the database that we want create.Database Provider: Specify the database that we want to use, whether it is SQL Server or MySQL etc.For that, we’ll be using ASP.NET Core dependency injection in a bit.īefore that let’s talk about the class constructor parameter options of the type DbContextOptions,Into this options parameter we’ve to pass following informations. Now let’s define DbContext class ImageDbContext for creating and managing the Database.Īs per the above DbContext class, after the DB migration, there will be a table – Images to save records corresponding to the model class ImageModel. In order to interact with the DB, we need an instance of the DbContext class ImageDbContext. IFormFile property ImageFile is a NotMapped property, meaning there won’t a corresponding table column in the database, just used to receive the posted image file during form submission like a view-model property. ImageName is used to save the name of the image. Now, let’s define DB model class ImageModel in a new folder – Models.Īpart from the Primary Key, we have columns Title and ImageName.

So right-click on the project from Solution Explorer, select Manage NuGet Packages, From Browse Tab– search and install respective following 3 packages. For that, we’ve to install corresponding NuGet Packages. Let’s create a database using Entity Framework Core. The above steps will create a brand new ASP.NET Core MVC project. A new window will be opened as follows, Select Web Application(MVC) and uncheck HTTPS Configuration. Once you provide the project name and location. Select Asp.Net Core Web Application template. In Visual Studio 2019, Go to File > New > Project (Ctrl + Shift + N). I just want to know, how can I get the text from the Kendo Editor and send the text value to the action method in the controller.Video Tutorial Create ASP.NET Core MVC Project Now I want that, when an admin user comes in and makes changes to the Editor text and hits 'Save' button, I want the text of the editor to get saved in database. (Html.BeginForm('Index', 'M圜ontrollerName', FormMethod.Post))
