Passing JSON To A PageMethod That Expects A List<T> Parameter?

Jan 13, 2010

I have an ASP.NET PageMethod with the following signature:

<WebMethod()> _ Public Shared Function SaveCodes(ByVal codes As List(Of Code)) As String

I am trying to pass a JSON object to the PageMethod from the client side, but I get an error that the type String cannot be converted to type of List<Code>.

Here is the json that I'm building on the client and sending to the method:

[code]....

I have been able to pass in simple data types and a single instance of the Code class, but I can't seem to find the magin to pass a List to the server method. Can anyone show me what I'm doing wrong?

Procedure Or Function Expects Parameter Which Was Not Supplied?

Apr 7, 2010

Driving me mad on a personal project; I know I've done this before but elsewhere and don't have the code. As far as I can see, I'm setting the parameter, I'm setting its value, the connection is open, yet when I try to fill the dataset I get the error 'Procedure or function expects parameter "@test" which was not supplied'. (This is obviously a simplified test! Same error on this or the real, rather longer code though.)

C#:

SqlCommand l_oCmd;
DataSet l_oPage = new DataSet();
l_oCmd = new SqlCommand("usp_test", g_oConn);

MVC :: Passing A List As A Parameter With BeginForm()?

Mar 2, 2011

I am using HTML.BeginForm to create a form on my page. I need to pass a list of classes I created as a parameter. It's done like this:

<%
using ( Html.BeginForm("DisplayCompanions", "CCDReviewController", new { CompanionList = Model.CompanionList} ) )
{ %>

When I click a "Continue" button (enclosed in the form tag), the "DisplayCompanions" method on my Controller ("CCDReviewController") should be called, as I've set a breakpoint on it. But it's not being called.

Note that Model.CompanionList is a generic list of classes that I created.

How To Get Ajax.Net PageMethod To Return JSON

Jan 12, 2010

I am using an AJAX.Net to call an ASP.Net PageMethod, which returns JSON serialized JSON data

{"d":"[{"Fromaddress":"testfrom1@test.com","Toaddress":"testto1@test.com"},{"Fromaddress":"testfrom2@test.com","Toaddress":"testto2@test.com"}]"}

The Response Header states the content type as

"Content-Type application/json; charset=utf-8"

However, the data is just available as a string, and does not seem to be available as JSON data from javascript. What do I need to do to work with the returned data as JSON from javascript?

ADO.NET : Receive The Error [Procedure Or Function 'search' Expects Parameter '@name',?

Nov 11, 2010

I have finally got my paging code for a datalist to work correctly. However, the stored procedure I use receives a Parameter called 'name' which is a VarChar 4. I'm having a little trouble implementing the handling of the 'name' parameter in the following code. I receive the error [Procedure or function 'search' expects parameter '@name', which was not supplied.]

Private Sub DataBind()
Dim objConn As New SqlConnection(ConfigurationManager.ConnectionStrings("SQL2005_504887_2onetennisConnectionString").ConnectionString) [code]....

I think it will look something like the following but I'm not sure because this syntax doesn't look like it would work with my above code.

cmdTest.CommandType = Data.CommandType.StoredProcedure
cmdTest.Parameters.Add(New SqlParameter("@TestParam", Data.SqlDbType.VarChar, 10))
cmdTest.Parameters("@TestParam").Value = "Testing"

Oracle 11g Stored Procedure - Expects A Parameter As A Number, But Receives A String?

Mar 23, 2011

we recently upgraded an application (.NET 2.0) that we maintain to use Oracle 11g. The application uses MS Enterprise Library 2.0. We've found that when the database.ExecuteNonQuery(Oracle.DataAccess.Client.OracleCommand) method is called, it bombs when the stored procedure expects a parameter as a number, but receives a string. This didn't happen prior to upgrading. If I cast the parameter to an Int, I don't recieve the error. Was something possible missed during the upgrade? The issue occurs regardless if we are hitting an 11g database, or a 10g database.

EDIT: I neglected to mention that this same issue does not occur when ExecuteDataReader is called (handles implicit conversion of the datatype).

Javascript - Passing JSON To Controller Action

Mar 7, 2011

I have the following javascript. Problem is if I enter one row in the table "ingredients" but I am getting 2 rows in the resulting pass to controller action after seralising into my C# object. But the second object is null? I checked the javascript and the variable "cnt" is 1 not 2. Why would that be?

[code]

$("#Save").click(function () {

Passing ID Of Element To A C# Web Service (using JSON) From JQuery?

Mar 9, 2010

I have an containing a list of divs that jQuery turns into progress bars. On .ready, I build a list of all of these progress bars and for each one, call a webservice that gets a value indicating how full the progress bar should be. In order to do this, I need to pass the ID of the div to the web service.

Because the divs are inside a ListView, I manually set the id to be id="completionbar_<%# Eval("MilestoneID") %>"

However, when I pass this id into my web service, it comes up as "undefined" every time. When I view the source, it looks like it's set correctly.

Here's the jQuery that calls my web service:

<script type="text/javascript" language="javascript">
$(document).ready(function() {
$(".MilestoneCompletion").progressbar({ value: 0 });
$.each($(".MilestoneCompletion"), function(index, barDiv) {

[Code].....

I'm thinking maybe the script is executing before the DIV id is set by the ListView databind?

MVC :: JQuery JSON Array Parameter?

Apr 21, 2010

.I am using VS2010 Ultimate in an out of the box HelloWorld MVC2 ProjectI am using JQuery 1.4.1I have the following code in my View:

function TestStringArray() {
var stringArray = new Array();
stringArray[0] = "item1";

[code]...

Forgetting my controller actually needs to return a Json result (I have a break on the return View() line), the values parameter is null. When I pass in a single string (change the type from List<String> to String in the controller, pass in a single string value from the View), it works fine. Looking at Fiddler, the array is passing the multiple values.I did some research and people are suggesting JSON.Stringify ion the JSON2 library, the JSON.NEt library, etc... Do I really need extra libraries? Microsoft didn't think of this scenario for out of the box? I assume the problem is any kind of complex type.

Passing A JSON Object To A Function On Server Side?

Jun 4, 2010

I'm trying to create a JSON object on client-side and pass to a server-side function. Then instantiate it on server-side using JSON string representation.

So I create jSON object on client-side

var myJsonObject = {
"arg1": var1,
"arg2": var2
}

and pass it in to

WebForm_DoCallback(controlID, myJsonObject , null, null, null, true);

When I try to retrieve this JSON object on server-size I get as a string representation of JSON [object Object]

So in following server-side function, the argument value is [object Object]

public void RaiseCallbackEvent(string jsonObj)

I was expecting a string representation of JSON object. How do I pass in a string representation?

C# - Passing JSON Serialized Data Via Hidden Field?

Mar 2, 2011

In ASP.NET WebForms I want to pass arbitrary data from server to client and back again. I am serializing to JSON and have been simply producing JavaScript that creates the object on the client. I have no problem sending data to the server with ajax, but there are situations where I also want to send a Javascript object data back to the server on postbacks. So I guess it needs to be in a hidden field.

1) What is the best way to do this in terms of minimizing complexity and optimizing space and efficiency? In researching this I discovered Protocol Buffers but there does not seem to be a good C# implementation. I did find one, but it was a couple years old and self-described as buggy so that scared me.

2) If I just pass a JSON string, how can I be sure it will be safe to include as the value for a hidden field? Is there any reason I might not want to do this? I could Base64 encode, but it seems like this adds a lot of overhead. What is considered the best or preferred method?

Passing Data From Controller To View Using JSon Object

Mar 4, 2011

I have the following to get the Json abject passed from the controller and populate the various textboxes in the view. However, nothing is happening even though controller is passing a valid Json object. What is wrong with this code?

<script language="javascript" type="text/javascript">
$(document).ready(function() {
var url = '<%=Url.Action("DropDownChange") %>';
$("#vendorID").change(function() {
var selectedID = $(this).val();
if (selectedID != "New Vendor Id") {
//$.post('Url.Action("DropDownChange","Refunds")', function(result) {
$.post(url, { dropdownValue: selectedID }, function(result) {
alert(selectedID);
$("#name").val(result.Name);
$("#city").val(result.City);
$("#contact").val(result.Contact);
$("#address2").val(result.Address2);
$("#address1").val(result.Address1);
$("#state").val(result.State);
$("#zip").val(result.Zip);
});
}
});
});
This is the code in my controller;
public JsonResult DropDownChange(string dropdownValue)
// This action method gets called via an ajax request
{
if (dropdownValue != null && Request.IsAjaxRequest() == true)
{
paymentApplicationRefund =
cPaymentRepository.PayableEntity(dropdownValue);
paymentApplicationRefund.Address1.Trim();
paymentApplicationRefund.Address2.Trim();
paymentApplicationRefund.Name.Trim();
paymentApplicationRefund.City.Trim();
paymentApplicationRefund.Contact.Trim();
paymentApplicationRefund.State.Trim();
paymentApplicationRefund.Zip.Trim();
return Json(paymentApplicationRefund,"application/json");
}
else
{
return null;

MVC :: Passing Json Collection Object From View To Action

Nov 1, 2010

I am trying to send json data from view to controller action. But the issue is the data is not populating in the action parameter List<Score>.

View Model:
public class Score
{
public int QuestionId { get; set; }
public int PrevAnswerId { get; set; }
public int CurrAnswerId { get; set; }
public string CurrAnswerName { get; set; }
}

Json Data look like:
[
{QuestionId:1, PrevAnswerId:3, CurrAnswerId:3, CurrAnswerName:'Known to Broker'},
{QuestionId:2, PrevAnswerId:7, CurrAnswerId:7, CurrAnswerName:'Completed'},
{QuestionId:3, PrevAnswerId:10, CurrAnswerId:10, CurrAnswerName:'Report'}
]

On window load, I will construct the Json object using "eval()" function and do some operation in the data before its save. On Save Click, I will call the action through the ajax call.

$.ajax({
url: url,
type: "GET",
dataType: 'json',
data: {score: ScoreJson},
contentType: "application/json; charset=utf-8",
success: function () {
alert("succes");
},
error: function () {
alert("error...");
} });

Action:
public ActionResult SaveScore(List<Score> score)
{
// do something...
}

But here score comming as collection of 3 elements with zero(for interger property)/null(for string property) values. When I checked in the request I found the data in "parama" property like.

"Score%5b0%5d%5bQuestionId%5d=1 &Score%5b0%5d%5bPrevAnswerId%5d=3 &Score%5b0%5d%5bCurrAnswerId%5d=3 &Score%5b0%5d%5bCurrAnswerName%5d=Known+to+broker&
Score%5b1%5d%5bQuestionId%5d=2 &Score%5b1%5d%5bPrevAnswerId%5d=7 &Score%5b1%5d%5bCurrAnswerId%5d=7 &Score%5b1%5d%5bCurrAnswerName%5d=Completed&
Score%5b2%5d%5bQuestionId%5d=3 &Score%5b2%5d%5bPrevAnswerId%5d=10 &Score%5b2%5d%5bCurrAnswerId%5d=10 &Score%5b2%5d%5bCurrAnswerName%5d=Travelers+Report&".

But I am not sure why it is not getting populated in the score list. One full day I spent for this issue but till now I didnt find the solution for this issue.
