When i call function sendmail() it is calling multiple time. please help where i am going to wrong
Master Page Code

Getting the result from controller but ajax call fetching error instead of success in MVC5 and C#

The controller is giving me the result and TempData["DCFormList"] is showing the count 3 (key, value and success message) but in the AJAX call I am getting alert("fail").
public ActionResult INTImportData()
{
if (Session["UserLogon"] != null)
{
BLINTForms objForm = new BLINTForms();
objDCFormList = new DCFormList();
int jobId = Session["Job_ID"] == null ? 0 : (int)Session["Job_ID"];
ViewBag.jobId = jobId;
objDCFormList.Form = objForm.GetINTFormTempDataByJobId(jobId);
TempData["DCFormList"] = objDCFormList.Form;
return View(objDCFormList.Form);
}
else
return Redirect("~/Account/Login");
}
function GetINTFormTempData(JobId) {
var result = null;
$.ajax({
type: "GET",
url: '/ImportForms/GetINTFormTempDataByJobId',
data: { jobId: JobId },
traditional: false,
success: function (data)
{
result = data;
alert ("JobId");
LoadINTData(result);
if (result.length > 0)
$(".upload").show();
else
$(".upload").hide();
},
error: function (data)
{
alert("fail");
Success = false;
}
});

List<DCForm> objDCFormList = new List<DCForm>();
DCForm objDCForm;
int record = 0;
try
{
objDatabaseHelper.AddParameter("Job_ID", jobId == 0 ? DBNull.Value : (object)jobId);
DbDataReader reader = objDatabaseHelper.ExecuteReader(BLDBRoutines.SP_GETINTFORMTEMPDATA, CommandType.StoredProcedure);

}
catch (Exception exce)
{
throw exce;
}
finally
{
if (objDatabaseHelper != null)
objDatabaseHelper.Dispose();
}
}

I have just tried to reproduce your case. Here are sample code. You can update your code to get from Database from my code.
Your controller:
public class ImportFormsController : Controller
{
public JsonResult INTImportData(int jobId)
{
//if (Session["UserLogon"] != null)
//{
BLINTForms objForm = new BLINTForms();
var objDCFormList = new DCForm.DCFormList();
//int jobId = Session["Job_ID"] == null ? 0 : (int)Session["Job_ID"];
//ViewBag.jobId = jobId;
objDCFormList.Form = objForm.GetINTFormTempDataByJobId(jobId);
//TempData["DCFormList"] = objDCFormList.Form;
//Response.StatusCode = (int)HttpStatusCode.OK;
return Json(objDCFormList.Form, JsonRequestBehavior.AllowGet);
//}
//else
//return Json("Login required", JsonRequestBehavior.AllowGet);
}
}
public class BLINTForms
{
public List<DCForm> GetINTFormTempDataByJobId(int jobId)
{
List<DCForm> objDCFormList = new List<DCForm>();
DCForm objDCForm;
int record = 0;
try
{
for (var i = 0; i < 5; i++)
{
objDCForm = new DCForm();
objDCForm.SerialNo = ++record;
objDCForm.PayerId = 100;
objDCFormList.Add(objDCForm);
}
return objDCFormList;
}
catch (Exception exce)
{
throw exce;
}
finally
{
}
}
}
public class DCForm : DataOperationResponse
{
public int SerialNo { get; set; }
public int PayerId { get; set; }
public class DCFormList : DataOperationResponse
{
private List<DCForm> _form = null;
public DCFormList()
{
if (_form == null)
_form = new List<DCForm>();
}
public List<DCForm> Form
{
get { return _form; }
set { _form = value; }
}
}
}
public class DataOperationResponse
{
//public string Message { get; set; }
}
I create a test in HomeController:Index with Index.cshtml
<input type="text" id="jobId"/>
<button onclick="GetINTFormTempData($('#jobId').val())">Get Data</button>
<script>
function GetINTFormTempData(JobId) {
var result = null;
$.ajax({
type: "GET",
url: '/ImportForms/INTImportData', //**change url**
data: { jobId: JobId },
traditional: false,
success: function(data) {
result = data;
alert("JobId");
alert(JSON.stringify(data));
LoadINTData(result);
if (result.length > 0)
$(".upload").show();
else
$(".upload").hide();
},
error: function(data) {
alert("fail");
Success = false;
}
});
}
</script>

You should use this
Change ActionResult to JsonResult and
return Json(objDCFormList.Form, JsonRequestBehavior.AllowGet);
TempData["DCFormList"] can not get value in your AJAX call.
And also check your url in route with url in ajax call.

If I get your question correctly and, and if you want to use ActionResult set result as Success with:
Response.StatusCode = (int)HttpStatusCode.OK;
So in your case:
public ActionResult INTImportData()
{
if (Session["UserLogon"] != null)
{
BLINTForms objForm = new BLINTForms();
objDCFormList = new DCFormList();
int jobId = Session["Job_ID"] == null ? 0 : (int)Session["Job_ID"];
ViewBag.jobId = jobId;
objDCFormList.Form = objForm.GetINTFormTempDataByJobId(jobId);
TempData["DCFormList"] = objDCFormList.Form;
Response.StatusCode = (int)HttpStatusCode.OK;
return View(objDCFormList.Form);
}
else
return Redirect("~/Account/Login");
}
I hope this helps.

object makes web method loop

If I delete this value = new { token = 1 } or convert to value = "" webmethod works fine, otherwise method get triggered after return repeatedly.
Why this happens how to solve?
[WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, UriTemplate = "login/{username}/{password}")]
public Result Login(string username, string password)
{
somecode..
if (user != null && user.Password == password)
{
return new Result { statusCode = "200", message = "Success", value = new { token = 1 } };
}
else
{
return new Result { statusCode = "401", message = "Fail", value = "" };
}
}
public class Result
{
public string statusCode { get; set; }
public string message { get; set; }
public object value { get; set; }
}
this didn't work too;
return new Result { statusCode = "200", message = "Success", value = new Token { token = "some string" } }

Try Like This
public Result Login(string username, string password)
{
int token=1;
Result response = new Result();
if (user != null && user.Password == password)
{
response.message = "Success";
response.statusCode = "200";
response.value = token;
}
else
{
response.message = "Fail";
response.statusCode = "401";
response.value = null;
}
return response;
}
public class Result
{
public string statusCode { get; set; }
public string message { get; set; }
public object value { get; set; }
}

Convert JSON data to querystring in C# GET request

What is the best way to convert a JSON object into querystrings to append to a GET Url? The POST is straight forward and gets read by my Web API backend.
{Name: 'Mike' } = ?Name=Mike
private static string MakeRequest(HttpWebRequest req, string data)
{
try
{
if (req.Method == Verbs.POST.ToString() || req.Method == Verbs.PUT.ToString() || req.Method == Verbs.DELETE.ToString())
{
var encodedData = Encoding.UTF8.GetBytes(data);
req.ContentLength = encodedData.Length;
req.ContentType = "application/json";
req.GetRequestStream().Write(encodedData, 0, encodedData.Length);
}
using (var response = req.GetResponse() as HttpWebResponse)
using (var reader = new StreamReader(response.GetResponseStream()))
{
return reader.ReadToEnd();
}
}
catch (WebException we)
{
if(we.Response == null)
{
return JsonConvert.SerializeObject(new { Errors = new List<ApiError> { new ApiError(11, "API is currently unavailable") }});
}
using (var response = we.Response as HttpWebResponse)
using (var reader = new StreamReader(response.GetResponseStream()))
{
return reader.ReadToEnd();
}
}
}

If the json object is flat as in your example, then
string json = #"{
""name"": ""charlie"",
""num"": 123
}";
var jObj = (JObject)JsonConvert.DeserializeObject(json);
var query = String.Join("&",
jObj.Children().Cast<JProperty>()
.Select(jp=>jp.Name + "=" + HttpUtility.UrlEncode(jp.Value.ToString())));
query would be name=charlie&num=123

I make this code to run in .Net Core:
public static string JsonToQuery(this string jsonQuery)
{
string str = "?";
str += jsonQuery.Replace(":", "=").Replace("{","").
Replace("}", "").Replace(",","&").
Replace("\"", "");
return str;
}
Example:
var _baseURI = "http://www.example.com/";
var endPoint = "myendpoint";
ExampleObjectModel requestModel = new ExampleObjectModel();
var requestModelJson = JsonConvert.SerializeObject(requestModel);
var url = string.Format("{0}{1}{2}", _baseURI, endPoint, requestModelJson.JsonToQuery());

Try this, work all object, in deep
public static class ExtensionMethods
{
public static string GetQueryString(this object obj, string prefix = "")
{
var query = "";
try
{
var vQueryString = (JsonConvert.SerializeObject(obj));
var jObj = (JObject)JsonConvert.DeserializeObject(vQueryString);
query = String.Join("&",
jObj.Children().Cast<JProperty>()
.Select(jp =>
{
if (jp.Value.Type == JTokenType.Array)
{
var count = 0;
var arrValue = String.Join("&", jp.Value.ToList().Select<JToken, string>(p =>
{
var tmp = JsonConvert.DeserializeObject(p.ToString()).GetQueryString(jp.Name + HttpUtility.UrlEncode("[") + count++ + HttpUtility.UrlEncode("]"));
return tmp;
}));
return arrValue;
}
else
return (prefix.Length > 0 ? prefix + HttpUtility.UrlEncode("[") + jp.Name + HttpUtility.UrlEncode("]") : jp.Name) + "=" + HttpUtility.UrlEncode(jp.Value.ToString());
}
)) ?? "";
}
catch (Exception ex)
{
}
return query;
}
}
To use: SomeObject.GetQueryString();

if your object(Entity) have a Children like this Entity :
public class Parent
{
public Child childs { get; set; } = new Child();
public int PageIndex { get; set; }
public int? PageSize { get; set; }
}
public class Child
{
public int Id { get; set; }
public string Name { get; set; }
}
