To update a dashboard in real-time in an MVC 5 application, you can use AJAX to periodically fetch updated data from the server and refresh the dashboard. Here's a step-by-step guide to achieving real-time updates in your MVC 5 application: 1. Set up a Controller Action: Create a controller action that returns the data needed for your dashboard. This action should return data in a JSON format. 2. Create a View for the Dashboard: Develop an MVC View that will render the dashboard using the data received from the controller action. 3. Implement AJAX Refresh: Use JavaScript and AJAX to periodically fetch updated data from the server and update the dashboard without a full page reload.

// Set the interval in milliseconds (e.g., 5000ms for 5 seconds) var refreshInterval = 5000; // Function to fetch and update dashboard data function updateDashboard() { // Use AJAX to call the action method $.ajax({ url: '/ControllerName/ActionMethodName', type: 'GET', dataType: 'json', success: function (data) { // Update dashboard content using the received data // Call functions to update charts, tables, or other dashboard elements }, error: function (xhr, status, error) { // Handle errors if necessary console.log(error); } }); } // Set up the timer to call the updateDashboard function at regular intervals setInterval(updateDashboard, refreshInterval); public class DashboardController : Controller { // Action method to fetch updated dashboard data public ActionResult GetDashboardData() { // Implement logic to retrieve the updated data for the dashboard // For example, fetch data from a database, external API, or any other data source var updatedData = GetDataFromDataSource(); // Return the data as JSON return Json(updatedData, JsonRequestBehavior.AllowGet); } // Sample method to retrieve data from a data source private List GetDataFromDataSource() { // Implement logic to fetch and process data // For example: // var data = db.DashboardData.ToList(); // return data; } }
