Hostname: Controller public ActionResult ActionName(string hostname) { string hn = hostname; // Use the value of hn as needed return View(); } HTML form: Ensure that the form is properly wrapped with the tags and has the correct class attribute ( form-horizontal ). Verify that the name attribute of the form ( name="HnForm" ) is correctly set. Make sure there is an input element in the form that corresponds to the account.HostName value you want to pass to the controller. JavaScript file (HostName.js): In your JavaScript file, make sure you're capturing the value of account.HostName correctly and setting it in the HTML element with the id hostname . Confirm that the JavaScript file is properly referenced in your HTML using the tag. Controller: Check that you have the necessary code in the controller action to handle the form submission and retrieve the value of account.HostName . Make sure the controller action is properly mapped to the HTML form submission.

There are a few possible reasons why hn could be null: Ensure that the account object is properly initialized and contains the HostName field with a value. You may need to check how the account object is being created or populated. Check if the HostName field is accessible within the account object. Verify that it is a public property or has a public getter method. Ensure that the Content method is correctly retrieving the value from account.HostName . Verify that the Content method is functioning as expected and returning the correct value. Check if the Content method is handling null values correctly. If account.HostName is null , the Content method might not be returning a valid value.
