View All. Nishan Aryal Updated date, Apr 18 Let's create an Ajax. Let's create an MVC Project.
If you don't know how to create a simple MVC Project, refer to my previous blogs. Once you have successfully created a MVC Project, we need to make sure that we have added reference to jquery. First, let's add jquery. The step is very simple. You can use Nuget Package Manager to install these files or you can do it manually. We use Nuget Package Manger to install these in our project. Step 1 Right click on Project. Step 3 Search for Microsoft. Ajax and Microsoft. Validation and Install in your project.This section of the manual looks at how to use the last option here as it is can be particularly convenient to load your data Ajax - for example via a data HTTP API feed or simply to separate your table data logic from your HTML.
Add added advantage of using Ajax loaded data is that you can enable DataTables' deferRender option to give a performance boost - this option, when enabled, will result in DOM elements being created only when they need to be drawn on the page, reducing the initial CPU load when the data is first inserted into the table.
Ajax data is loaded by DataTables simply by using the ajax option to set the URL for where the Ajax request should be made.
DataTables requires an array of items to represent the table's data, where each item in the array is a row. The item is typically an object or an array discussed in more detail below - so the first thing we need to do is tell DataTables where that array is in the data source.
Consider, for example, the following three JSON data objects shown on the left below, as you will be able to see each of the three structures contain the same data for the array of data to be displayed in the table, but the location of that array if different in each.
Each is perfectly valid and can be used in different circumstances - there is no single "correct way"! The ajax. An empty string is a special case which tells DataTables to expect an array as in the first example above. Now that DataTables knows where to get the data for the rows, we need to also tell it where to get the data for each cell in that row - this is done through the columns. Let's consider again three different data formats, again shown on the left below - only a single row of data is shown in each case i.
As you will be able to see, in each of the three cases, the same data is available for the row, but the structure of the JSON data is different. We use the columns. Like the ajax. It can also be given in other forms such as an index for accessing an array. The corresponding initialisation of DataTables for the three data structures is shown on the right. This is because the default value for columns.
Loading data Ajax data is loaded by DataTables simply by using the ajax option to set the URL for where the Ajax request should be made. Data array location DataTables requires an array of items to represent the table's data, where each item in the array is a row. The three data structures are each shown with their corresponding DataTables initialisations.Every web developer uses a few jQuery components.
The biggest problem is customization. We are built this project on ASP. But it wants to give back some values. Ajax sends some values to the server and gets the result back.
This process is a little complicated. You should create an ASP. It is typically, no required authanticate etc. Now, create a simple model object to generate a datatable.
Use " Student. This class contains the following lines:. We should create a controller with the name DTSampleController. Give "DTSampleController" for name. We are using the index method for the presentation datatable in view. Create a view for the index method. However, we dont give a method because we using the student model during ajax operations. Ok, we are in the view screen. Before proceeding we must add the jquery.
After initializing jquery. Note that there is no tbody tag. This is because AJAX is going to generate it. Now write datatable scripts under the page. Your display should match the above image. Next we create a method in the controller for ajax operations.
Our idea is to create sample data, filter it and present it. You should use real data model in the real world. If you see page as shown, everything is OK. After we are going to do a small test for filter.

Let's assume that we have a page that contains multiple partial views and data from various sources.
So we can load each partial view using AJAX individually, it will improve the user experience because the components that can be loaded earlier won't be delayed until all the components load. As soon as each control loads, they will be available to the user on the screen. I have used ASP. I have created a main View called here HomePage. So I'll show you how easily we can load these controls viaAjax. It will make the page more intuitive and seamless to users.
I am showing simple data in these controls and one control display the details of the users and other control displays product details. For this, I have created two models, User and Product.

DataTables Options snapshot. And the main option is Ajax which we are going to use for calling an Action Method for getting data to bind DataTables Grid the data is in Json format.
And data type we are going to set as Json. Finally, the second to last option is columns which are used for initialization of DataTables grid. Add that property which you need to render on the grid, which must be defined in this columns option. At last, we need to render button in the grid for editing data and deleting data. In this action method, we are going to get all Customer records from the database to display and on the basis of the parameter we are going sort data, and do paging with data.
We are doing paging and filtering of data on the server side; that why we are using IQueryable which will execute queries with filters on the server side. For using OrderBy in the query we need to install System. Dynamic package from NuGet packages. Snapshot while adding System. After adding the package, next, we see the complete code snippet and how to get data and do paging and filtering with it.
