This is my Controller to post data into database:-

C#

[HttpPost]
        public ActionResult UpdateGLCode(string Glcode, string ReportId, string HeadName)
        {
            SqlConnection con = null;
            SqlCommand cmd = null;

            con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["System.Data.SqlClient"].ToString());
            con.Open();
            cmd = new SqlCommand("AliUpdateGLCodeInRLMaster", con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.Add("@Criteria1", SqlDbType.VarChar).Value = Glcode;
            cmd.Parameters.Add("@Criteria2", SqlDbType.VarChar).Value = ReportId;
            cmd.Parameters.Add("@Criteria3", SqlDbType.VarChar).Value = HeadName;

            cmd.ExecuteNonQuery();
            con.Close();
            return RedirectToAction("Index", new { msg = "Record Saved Successfully." });
        }

and below is my Ajax:

HTML

$("#btnRLMasterSave").click(function () {
        alert("HI");
        $.ajax({
            url: "/RLMaster/UpdateGLCode",
            data: { Glcode: $('#Glcode').val(), ReportId: $('#ReportId').val(), HeadName: $('#HeadName').val() },
            type: "POST",
            dataType: "json",
            success: function (data) {
                alert("HI");
            },
            error: function () {
                alert("Failed");
            }
        });
    });

I am very sure that I am not correct.
But this is all I can write of my own.
Please correct or any suggestions would be highly appreciated.

Javascript code:
1. Add jQuery reference in your view page.

JavaScript

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>

2. Add below javascript code.

JavaScript

<script>
   $(function () {
        $("#btnRLMasterSave").click(function () {
	alert("HI");
	$.ajax({
		url: "/RLMaster/UpdateGLCode",
		data: JSON.stringify({ Glcode: $('#Glcode').val(), ReportId: $('#ReportId').val(), HeadName: $('#HeadName').val() }),
		type: "POST",
		contentType: 'application/json; charset=utf-8',
		dataType: "json",
		success: function (data) {
			alert(data);
		},
		error: function () {
			alert("Failed");
		}
	});
     });
});
</script>

Controller Code:

C#

[HttpPost]
public ActionResult UpdateGLCode(string Glcode, string ReportId, string HeadName)
{
	SqlConnection con = null;
	SqlCommand cmd = null;

	con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["System.Data.SqlClient"].ToString());
	con.Open();
	cmd = new SqlCommand("AliUpdateGLCodeInRLMaster", con);
	cmd.CommandType = CommandType.StoredProcedure;
	cmd.Parameters.Add("@Criteria1", SqlDbType.VarChar).Value = Glcode;
	cmd.Parameters.Add("@Criteria2", SqlDbType.VarChar).Value = ReportId;
	cmd.Parameters.Add("@Criteria3", SqlDbType.VarChar).Value = HeadName;

	cmd.ExecuteNonQuery();
	con.Close();
	
	return Json("Success", JsonRequestBehavior.AllowGet);
}
