As Paddy mentioned: if you use an overload of UrlHelper.Action() that explicitly specifies the protocol to use, the generated URL will be absolute and fully qualified instead of being relative. It got a lots of examples in the link I gave above. I therefore made myself a dedicated Razor Page for my filter. Visual Studio automatically includes jQuery on the Shared/_Layout.cshtml page, so every View ought to be able to access it already. Calling the PUTcar method using Ajax and updating the data of the Web API. What is Ajax? Build (or wait for VS to perform a restore) to get rid of warnings and then rename the MyFeature folder to Editor and delete Page1.cshtml and its PageModel class file Add a Razor Page named Index.cshtml to the Pages folder in the Editor area with the following code: Code that needs to run before each view or page should be placed in the _ViewStart.cshtml file. $.ajax({ // edit to add steve's suggestion. I'd recommend using Html.RenderAction and PartialViewResults to accomplish this; it will allow you to display the same data, but each partial view would still have a single view model and removes the need for a BigViewModel. Call Web API using Jquery AJAX Creating Controller and View You can create a new controller and view for displaying the data returned by Web API. So your view contain something like the following: @Html.RenderAction("Login") @Html.RenderAction("Register") Where Login & Modify NoResults.cshtml to a Partial. Lets make it a little less boring and get it ready to make AJAX calls. So your view contain something like the following: @Html.RenderAction("Login") @Html.RenderAction("Register") Where Login & Razor Page. Call this view Carstock for the demo of consuming the Web API. The statements listed in _ViewStart.cshtml are run before every full view (not layouts, and not partial views). After adding the model properties now I will consume the HTTP service developed using the ASP.NET Web API in a simple cshtml page with jQuery and Ajax. First thing there is no need of having two different versions of jquery libraries in one page,either "1.9.1" or "2.0.0" is sufficient to make ajax calls work.. It got a lots of examples in the link I gave above. Here is your controller code: public ActionResult Index() { return View(); } public ActionResult FirstAjax(string a) { return Json("chamara", JsonRequestBehavior.AllowGet); } It works as a master layout of the page but if you are not using it in your View then include the jQuery file specifically. This is how you call an instance method on the Controller: @{ ((HomeController)this.ViewContext.Controller).Method1(); } This is how you call a static method in any class @{ SomeClass.Method(); } This will work data-ajax-success: Gets or sets the JavaScript function to call after the page is successfully updated. When you call any async EF method, always use the await keyword. Solution 2: A dedicated Razor Page just for the AJAX request. If you are using VS Code, you can do this by executing dotnet new page -o Pages/Admin -n Index -na AuthenticationSample.Pages.Admin from the terminal. What is Ajax? This is how you call an instance method on the Controller: @{ ((HomeController)this.ViewContext.Controller).Method1(); } This is how you call a static method in any class @{ SomeClass.Method(); } This will work var token = $('input[name="`__RequestVerificationToken`"]').val(); Step 2: Pass the token in the AJAX call Build web apps and services that run on Windows, Linux, and macOS using C#, HTML, CSS, and JavaScript. First: Edit Your AppStart Page If you have built the Demo application in this tutorial, you already have a page called _AppStart.cshtml with the following content: I gave the following values to it: 1. type as POST it means jQuery will make HTTP POST type of request to the Add Action. ; 2. url as @Url.Action(Add) it should be URL to I have added few CSS bootstrap classes and applied some design to make the form pretty. It sends a GET Ajax call to the razor page mentioned in the calling form (We will see this later.) We will now populate them, using AJAX call. The JavaScript on the page (Create.cshtml) calls a controller action to get the data from the server asynchronously. ; 2. url as @Url.Action(Add) it should be URL to We will now populate them, using AJAX call. The controller action's job is to call the repository to get the data, then convert it from an IEnumerable of SelectListItems to JSON I wrote a blog post called How to build absolute action URLs using the UrlHelper class in which I suggest to write a custom extension method for the sake of readability: Open StoreManager's Index View. Now, to call the function, add an onclick event on the employee name hyperlink and call the function. Call Web API using Jquery AJAX Creating Controller and View You can create a new controller and view for displaying the data returned by Web API. The typical example for an ajax call is like this.

Content pages reference their layout page via the Layout property of the page, which can be assigned in a code block at the top of a content page to point to a relative location: @{ Layout = "_Layout"; } While securing the HTTP API & the application service prevents unauthorized users to use the services, they can still navigate to the book management page. Replace the lines that show the Artist Name and Album's Title. For this jQuery must be included in the on the View. The statements listed in _ViewStart.cshtml are run before every full view (not layouts, and not partial views). When you call any async EF method, always use the await keyword. Razor Page. While they will get authorization exception when the page makes the first AJAX call to the server, we should also authorize the page for a better user experience and security. Step 1: Get the token. This is how you call an instance method on the Controller: @{ ((HomeController)this.ViewContext.Controller).Method1(); } This is how you call a static method in any class @{ SomeClass.Method(); } This will work To demonstrate the use of email, we will create an input page for support, let the user submit the page to another page, and send an email about the support problem. As Paddy mentioned: if you use an overload of UrlHelper.Action() that explicitly specifies the protocol to use, the generated URL will be absolute and fully qualified instead of being relative. When we run this code, the preview will be, as shown below. For Now I used Index Method of Home Controller to call Web API just created. To disable this for all pages, edit the _ViewStart.cshtml (in the root, under the 'Views' folder), and ensure that it contains the following: @{ Layout = null; } And to enable the template for any specific view, the following can be added to the .cshtml file for that view, to enable the template: By convention, the _ViewStart.cshtml file is located in the Pages (or Views) folder. When you call any async EF method, always use the await keyword.

Modify NoResults.cshtml to a Partial. An EF context isn't thread safe: don't try to do multiple operations in parallel. function PutData() { function PutData() { When the end-user makes a call to an MVC 6 application requesting a View, a response in the form of a View is returned when the action is executed. And call this as a Partial view in the parent view @Html.Partial("Results") You might have to pass the Customer collection as a model to the Result action or in a ViewDataDictionary due to reasons explained here: Can't access ViewBag in a partial view in ASP.NET MVC3 SignalR also provides a simple, high-level API for doing server to client RPC (call JavaScript functions in your clients' browsers from server-side .NET code) Any time a user refreshes a web page to see new data or the page implements Ajax long polling to retrieve new data, you can use SignalR. However if the Controller or the Action is applied with the Authorize attribute, then the request processing on the server sends the Login Page response to the client. Because we are introducing a new jQuery reference, we also need to remove, or comment out, the default jQuery reference in the _Layout.cshtml file (in the Views/Shared folder). For Now I used Index Method of Home Controller to call Web API just created. Here is the code: Filter.cshtml. Like ViewImports.cshtml, _ViewStart.cshtml is Since were using jQuery to make these AJAX requests, well obviously need to include jQuery. The runtime will then perform the following steps: (the same-origin policies that govern AJAX requests do not necessarily apply to HTTP cookies). Similarly, jQueryModalPost from Line 23 - 45 This function is responsible to display the bootstrap modal which contains the form to edit/create records. Explanation: I defined 2 variables (val1 & val2) that contain 2 numbers which are 5 and 2.Next I defined the .ajax() method of jQuery to call the Add action method given in the Controller.. I'd recommend using Html.RenderAction and PartialViewResults to accomplish this; it will allow you to display the same data, but each partial view would still have a single view model and removes the need for a BigViewModel. To disable this for all pages, edit the _ViewStart.cshtml (in the root, under the 'Views' folder), and ensure that it contains the following: @{ Layout = null; } And to enable the template for any specific view, the following can be added to the .cshtml file for that view, to enable the template: Calling the PUTcar method using Ajax and updating the data of the Web API. Call this view Carstock for the demo of consuming the Web API. Add a new Razor Page to the Admin folder named Index. I wrote a blog post called How to build absolute action URLs using the UrlHelper class in which I suggest to write a custom extension method for the sake of readability: data-ajax-update: Gets or sets the ID of the DOM element to update by using the response from the server. Here is the code: Filter.cshtml. I have added few CSS bootstrap classes and applied some design to make the form pretty. Build web apps and services that run on Windows, Linux, and macOS using C#, HTML, CSS, and JavaScript. By default it is included in the __Layout.cshtml. To take advantage of the performance benefits of async code, make sure that any library packages used also use async if they call any EF methods that cause queries to be sent to the database. AJAx is a client-side script that communicates to and from a server without interfering with the display and behaviour of the existing page.AJAx stands for Asynchronous JavaScript and XML.Ajax is not a single technology HTML and CSS can be used in combination to mark up and style information.AJAX is not a programming language but The controller action's job is to call the repository to get the data, then convert it from an IEnumerable of SelectListItems to JSON Similarly, jQueryModalPost from Line 23 - 45 This function is responsible to display the bootstrap modal which contains the form to edit/create records. Content pages reference their layout page via the Layout property of the page, which can be assigned in a code block at the top of a content page to point to a relative location: @{ Layout = "_Layout"; } The controller action's job is to call the repository to get the data, then convert it from an IEnumerable of SelectListItems to JSON What makes this a layout page is the call to the RenderBody method. Task 2 - Truncating Text in the Page. Hence, with HTML of both dropdowns, my cshtml page looks, as shown below. Step 1 Open Views => Home => Index.cshtml Step 2 Lets remove unnecessady HTML codes.
