In my javascript code I am getting json string from cs file
var tmpString="<%=resultset2%>";
In cs I am concatenating strings to build json string. Here is an issue the json string is returned as a string and it has " with it.
"[{id:'1',name:'Aik'},{id:'2',name:'Aik or Aik'}]"
Because of " in beginning and end javascript code treat it as a string.

using jquery json
I try to use the jquery + json to get all elements in form and build a JSON var to post in a ASP.NET MVC method.
[Code]....
It method get all fields in a form and build a JSON, but it dont put JSON inside JSON.
Example:
If i have the follow form:
<input name="person.name"><input name="person.age"><input name="person.address.street">
The serialized string build a JSON like this
{ "person.name": "??", "person.age": "??", "person.address.street": "??" }
I need a plugin or some function to generate like this:
{ "person": { "name" : "??", "age" : "??", "address":{ "street": "??" } } }
I am unable to convert JSON string to .net object in asp.net. I am sending JSON string from client to server using hidden field (by keeping the JSON object.Tostring() in hidden field and reading the hidden field value in code behind file)
Json string/ Object:
[[{"OfferId":"1","OrderValue":"11","HostingTypeID":"3"},
{"OfferId":"1","OrderValue":"11","HostingTypeID":"3"},
{"OfferId":"1","OrderValue":"11","HostingTypeID":"3"},
{"OfferId":"1","OrderValue":"2","HostingTypeID":"3"},
[Code]....
While converting i am getting following error:
Expecting element 'root' from namespace ''.. Encountered 'None' with name '', namespace ''.
I have DataReader that holds the results from a stored procedure caal. The results consist of two fields ...
UserID
UserName
Normally I bind these results to an ASP.NET dropdownlist control ...
ddlUserList.DataSource = rdr // rdr is the DataReader
ddlUserList.DataTextField = "UserName"
ddlUserList.DataValueField = "UserID"
ddlUserList.DataBind()
However I am now trying to accomplish the same thing using jQuery AJAX. What I am stuck on is how to manually convert the dataset held in the DataReader to JSON. How are multiples values separated? Does this look correct?
{{"UserID":1, "UserName":"Bob"}, {"UserID":2, "UserName":"Sally"},{"UserID":3, "UserName":"Fred"}}
I realize there are libraries out there such as JSON.NET to handle the serialization but I am in the learning stage now and want to make sure I understand everything from the bottom up.
I have a text file named gisQuery129.json that is created using Json.NET - [URL] There is an example on how to create a JSON file and I have done that successfully, but I want to read the file on a page load event and add the values to .NET textbox controls for input values in a query. The created file looks like the following:
{
"myData": {
"randomNumber": "129",
"Application": "MyMapApp",
"FeatureId": "ALL",
"Feature": "ALL",
"spatialQuery": "FEATURE_ID= '11111' AND REQ_SEQ_NUM= 1 AND RAND_PARAM= 129 OR FEATURE_ID= '22222' AND REQ_SEQ_NUM= 2 AND RAND_PARAM= 129"
}
}
I want to read the data in the above sample JSON data and then populate my textboxes something like this:
txtRandParam.text = "129"
txtApplication.text = "MyMapApp" and three more text boxes after that.
I've been tasked with implementing a JSON feed on an asp.net website that will be consumed by 3rd party apps (such as IPhone, Android, etc) and I'd like to follow best practices.
An example of what I'd like to achieve would be something similar to: [URL]
I've chosen the JSON.net api as this seems to be highly recommended.
My Google-fu must be failing me as I can't find a single full example code for an Asp.net web application with JSON.net implemented on it, so I've no real concept of where to begin.
My question is fairly simple:
Should I create this sort of feed as an ASPX, or ASHX file? Or even a .NET Web Service? (Remember that the tools that will be using this feed are on external apps like IPhones, etc)
I created a test feed in both ASHX and ASPX format ... here is the code (I'm using Subsonic to populate the collection) ... are either of these along the correct lines?
ASPX:
[Code]...
public class Package
{
public Package()
{
name = "";
type = new List<Dictionary<string, string>>();
}
public string name { get; set; }
public List<Dictionary<string, string>> type { get; set; }
}

How to call a method on a server side from JSON. Below is the code I am using

What is the quickest way once I have JSON array in hard to actually manufacture HTML? I'm thinking it's iterating the JSON arrays pulling out needed data and concatinating an HTML string that I pass to eval()? Is there a faster way?
View 1 RepliesI'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?
I am getting this JSON string from an ASP.Net webservice:
{"d":{"Table":[{"col1":123,"col2":"name","col3":"name","col4":100,"col5":"/Date(1153033200000)/"},{"col1":123,"col2":"name","col3":"name","col4":101,"col5":"/Date(1153033200000)/"},{"col1":123,"col2":"name","col3":"name","col4":102,"col5":"/Date(1153033200000)/"}]}}
In my jQuery how do I reference the Table code so I can loop through the data?
msg.d[i].col1
What am I missing? msg.d.table[i]?

I was wondering if there is an easy way to submit a form or a collection of fields with jquery and json to a C# server-side script. I was thinking of a script that retrieves all data from elements with an attribute called 'form' (yes, we just add a new attribute to for example a textbox or textarea). Thus, the script searches for all form attributes with form='myform' and then submits the data as an form object. In server-side code we know how to deal with the data. Does someone has such a script? Or can I inspire someone to develop such a script? (I have the idea, not the skills) ..also, sessionstate needs to be available (cookie).

I am developing a webiste in ASP.NET. On one of the pages page named menu.aspx, with the help of a certain login, I am getting the output in this format

I am using this code to get the output on the JSON form.

However, I must get the output only in simple JSON on the page without any HTML.

I have a class that contains an enum property, and upon serializing the object using JavaScriptSerializer, my json result contains the integer value of the enumeration rather than its string "name". Is there a way to get the enum as a string in my json without having to create a custom JavaScriptConverter?
