Progressive Loading from SQL Server to MVC View with AJAX Pagination

Implementing Progressive Loading from SQL Server to MVC View with AJAX Pagination

To implement progressive loading from SQL Server to an MVC View using AJAX, follow these steps:

  1. Create an MVC Controller: Create a new Controller in your MVC project that will handle the AJAX requests and return data from the SQL Server.
  2. Write a SQL Query: Write a SQL query that retrieves the data you want to display in the View. This query should include an ORDER BY clause to ensure that the data is retrieved in a consistent order.
  3. Create an AJAX Endpoint: Create a new Action method in your Controller that will act as an AJAX endpoint. This method should return JSON data representing a portion of the SQL query results.
  4. Create a Partial View: Create a new Partial View in your MVC project that will display the data retrieved from the AJAX endpoint.
  5. Implement AJAX Pagination: Implement AJAX pagination in your Partial View using JavaScript and jQuery. This involves adding event listeners to the pagination links and making AJAX requests to the endpoint to retrieve the next page of data.

Here’s some sample code to get you started:

In your Controller:

public ActionResult GetData(int page)
    int pageSize = 10;
    int skip = (page - 1) * pageSize;
    var data = db.MyTable.OrderBy(x => x.Id).Skip(skip).Take(pageSize);
    return Json(data, JsonRequestBehavior.AllowGet);

In your Partial View:

@model IEnumerable<MyApp.Models.MyTable>
    @foreach (var item in Model)

<div id="pagination">
    @for (int i = 1; i <= ViewBag.PageCount; i++)
        <a href="#" class="page-link" data-page="@i">@i</a>

    $(function() {
        $('#pagination').on('click', '.page-link', function(e) {
            var page = $(this).data('page');
                url: '@Url.Action("GetData", "MyController")',
                data: { page: page },
                success: function(data) {

This code implements progressive loading of data from SQL Server to an MVC View using AJAX pagination. It retrieves a page of data from the SQL Server using an AJAX endpoint, and displays it in a Partial View with pagination links that trigger additional AJAX requests for more data.
