If you still want to stick with initial design, removed the "location.href='/';" because the page should not redirect back to index and remain on the page. if (n == 3) { return Content( " alert('Message does not Send Successfully due to invalid credentials !'); " ); } However, I like the changes that you had made using TempData["Success"]

instead of showing Success or Failure message via javascript i used tempdata in myview as @if (TempData["Success"] != null) { @TempData["Success"] } My controller is just setting if (n == 3) { TempData["Success"] = "Message does not Send Successfully due to invalid credentials."; }

my controller is like below [HttpPost] public ActionResult SendSMS(ConfigurationSettings sm) { string API_KEY = sm.API_KEY; string API_SECRET = sm.API_SECRET; double TO = Convert.ToDouble(sm.To_Number); string Message = sm.TextMessage; string sURL; sURL = "https://www.thetexting.com/rest/sms/json/message/send?api_key=" + API_KEY + "&api_secret=" + API_SECRET + "&to=" + TO + "&text=" + Message; if (ModelState.IsValid) { try { using (WebClient client = new WebClient()) { string s = client.DownloadString(sURL); var responseObject = Newtonsoft.Json.JsonConvert.DeserializeObject (s); int n = responseObject.Status; if (n == 3) { return Content(" alert('Message does not Send Successfully due to invalid credentials !');location.href='/'; "); } else { return Content(" alert('Message Send Successfully !');location.href='/'; "); } } } catch (Exception ex) { ModelState.AddModelError("", "Error in sending Message"); ex.ToString(); } return View("Index"); } else { ModelState.AddModelError("", "Error in sending Message"); return View("Index"); } } } my view is like below : @model TheTextingDemo.Models.ConfigurationSettings TheTexting SMS GateWay Demo .required:after { padding-left: 10px; content: "*"; font-weight: bold; color: red; } @Html.ValidationSummary(true, "Correct The Errors first.") @using (Html.BeginForm("SendSMS", "Home", FormMethod.Post)) { Account Information Note: all the fields with (*) are required fields. @Html.LabelFor(model => model.API_KEY, new { @class = "required" }) @Html.TextBoxFor(model => model.API_KEY) @Html.ValidationMessageFor(model => model.API_KEY) @Html.LabelFor(model => model.API_SECRET, new { @class = "required" }) @Html.TextBoxFor(model => model.API_SECRET) @Html.ValidationMessageFor(model => model.API_SECRET) @Html.LabelFor(a => a.To_Number, new { @class = "required" }) @Html.TextBoxFor(a => a.To_Number) @Html.ValidationMessageFor(a => a.To_Number) @Html.LabelFor(a => a.TextMessage, new { @class = "required" }) @Html.TextAreaFor(a => a.TextMessage, new { @Value = "test" }) @Html.ValidationMessageFor(a => a.TextMessage) Note: Number must be international format like for USA : 13306807200 (where prefix 1 is USA country dialing code) }

Hi Mark Tabor, You can pass the text box values using ajax method in view Kindly find the below code, $.ajax({ type: "POST" , url: '@Url.Action("YouControllerName", "ActionName")' , contentType: "application/json; charset=utf-8" , data: { Textbox1: $( '#Textbox1' ).val(),Textbox2:$( '#Textbox2' ).val() }, // your field name and model name should be same , then only it will automattically bind dataType: "json" , success: function () { alert( 'Success' ); }, error: errorFunc }); //controller Public ActionResult ActionName(ModelName modelObject) { // Write your code here to save the data return Json( true ,JsonRequestBehavior.AllowGet); } //Model public class SampleModel { public string Textbox1{ get ; set ;} public string Textbox2{ get ; set ;} }
