How to hide Url parameter in ASP.Net MVC5

In ASP.Net MVC5, you can hide URL parameters by using various techniques. One common approach is to use the POST method instead of the GET method when submitting form data. By doing so, the parameters will be sent in the request body instead of being appended to the URL.

Here's an example of how you can achieve this:

// View
@using (Html.BeginForm("ActionName", "ControllerName", FormMethod.Post))
{
    // Form fields and submit button
    // ...
}

// Controller
[HttpPost]
public ActionResult ActionName(FormViewModel model)
{
    // Process the form data
    // ...

    return RedirectToAction("Success");
}

In this example, the form is submitted using the POST method and the form data is sent to the ActionName method in the specified controller. After processing the form data, you can redirect the user to a success page using the RedirectToAction method.

By using the POST method, the URL will only display the main URL without any parameters. However, please note that this approach may not be suitable for all scenarios, especially when you need to share or bookmark specific URLs.

Hello Thulsiram,

You can do it in couple of ways to hide parameter,

1. Use POST Requests: instead of get request use post request and pass it in body 
2. Use Session Variables: use session variable to store parameter and use that variable
3. Encrypt Parameters: you can encrypt your parameter and secure it.

Hi Thulasiram,

By following below principles  you can achieve a clean and user-friendly experience without exposing parameters in the URL when a button is clicked in ASP.NET MVC.

1. Use POST Requests: Ensure that the action you want to perform when clicking the button is decorated with the [HttpPost] attribute. This way, the action will only respond to POST requests, and the parameters won't be visible in the URL.

2. Redirect After Processing: If the button click triggers some processing on the server, consider redirecting to another action using RedirectToAction. This will change the URL in the browser, and only the URL for the new action will be visible.

3. HTML Form: If the button is part of a form, make sure the form is set to use the POST method (FormMethod.Post). This ensures that the form data is submitted in the body of the HTTP request rather than in the URL.

4. Update Views Accordingly: Adjust your views and actions based on the POST approach. For example, you might have one action to display a form (HTTP GET), and another action to handle the form submission (HTTP POST). The latter action can then redirect to another action if needed.
