To retrieve data from a database based on selected checkbox values in ASP.NET MVC, you'll need to follow these steps: Create a Model : Define a model that represents the data you want to retrieve. public class Item { public int Id { get; set; } public string Name { get; set; } public bool IsSelected { get; set; } } Create a View : Create a view that displays the checkboxes. @model IEnumerable @foreach (var item in Model) { @item.Name } Submit Create a Controller : Create a controller action to handle the form submission and retrieve the selected data. public class HomeController : Controller { private readonly YourDbContext _context; public HomeController(YourDbContext context) { _context = context; } [HttpPost] public IActionResult RetrieveData(int[] selectedItems) { var selectedData = _context.Items .Where(item => selectedItems.Contains(item.Id)) .ToList(); return View(selectedData); } } Create a View for Displaying the Retrieved Data : Create a view to display the retrieved data. @model IEnumerable Selected Items @foreach (var item in Model) { @item.Name }

Retrieving data from a database based on selected checkbox values in ASP.NET MVC involves a few steps. Here's a general overview: 1. Front-end Setup : - Create a form in your view containing checkboxes for the criteria you want to filter data on. - Ensure each checkbox has a unique value to identify it when the form is submitted. 2. Controller Logic : - Receive the form submission in your controller action method. - Extract the selected checkbox values from the form data. - Construct a query based on the selected checkbox values to retrieve data from the database. 3. Database Interaction : - Use Entity Framework or any other ORM tool to interact with your database. - Build a query dynamically based on the selected checkbox values. - Execute the query to fetch relevant data. 4. Display Data : - Pass the retrieved data to your view for rendering. - Display the data in the desired format, such as a table or a list. Below is a simplified example to illustrate how you can achieve this: View (Checkbox Form) : Criteria 1 Criteria 2 Controller : public ActionResult FilterData(string[] criteria) { // Use the criteria array to build your query var filteredData = YourDatabaseContext.YourTable.Where(item => criteria.Contains(item.CriteriaColumn)); return View(filteredData); } This is a basic illustration and may need to be adapted to fit your specific database structure and requirements. Remember to handle error checking, data validation, and potential SQL injection vulnerabilities in a production scenario. I hope this explanation helps you understand how you can retrieve data from a database based on selected checkbox values in ASP.NET MVC. Feel free to ask if you need further clarification or additional details!
