Successful when you submit the form, if it is incomplete or if it gets an error, how do I add that it cannot be sent?

and ;

Also, for example, rules such as the name must be at least 5 characters and the phone must be at least 11 digits.

    Hi @Harun Ergün

    You can perform judgments by adding the attribute "onsubmit" to the form tag.

    Example:

    Model:

     public class Student
        {
            
            public string Name { get; set; }
            public int Telephone { get; set; }
        }
    

    Controller:

     public class HomeController : Controller
        {
            public ActionResult Index()
            {
                return View();
            }
            public ActionResult About()
            {
                ViewBag.Message = "Your application description page.";
                return View();
            }
            public ActionResult Contact()
            {
                ViewBag.Message = "Your contact page.";
                return View();
            }
            [HttpPost]
            public ActionResult form1(string txtName,string txtTel)
            {
                ViewBag.Name = txtName;
                ViewBag.Tel = txtTel;
                
                return View("Index");
            }
        }
    

    View:

    <form action="form1" method="post" onsubmit="return demo()">
        <table>
            <tr>
                <td>Enter Name: </td>
                <td><input type="text" name="txtName" id="txtName" /></td>
            </tr>
            <tr>
                <td>Enter Tel: </td>
                <td><input type="number" name="txtTel" id="txtTel" /></td>
            </tr>
            
            <tr>
                <td colspan="2"><input type="submit" value="Submit Form" /></td>
            </tr>
        </table>
    </form>
    <script>
        function demo() {
            var a = document.getElementById("txtName");
            var b = document.getElementById("txtTel");
            var txtName = a.value;
            var txtTel = b.value;
            if (txtName.length < 5 && txtTel.length < 11) {
                alert("Error");
                return false;
            }
                
        }
    </script>
    

    In this way, a judgment will be made after the data is submitted. Submissions will only be made if they meet the requirements.

    Output:Label

    Best Regards

    Your asking about input validation. See the official documentation for how to use validation in MVC.
