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 use the JavaScriptSerializer class of ASP.net to serialize my object and return it to the client side. How can I deserialize the string using JavaScript?
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; } } [code]...
I have read about desearlizing a json file into class fields which I understand. But what I cannot find in a tutorial is how to read in the json data. Everyone just adds the data to a variable and uses it. I will be passing in a json file from a mobile app. I know I should use a web service but for now I want to use an asp.net ASPX page to do this. I will be using the newtonking json control.
I'd like to read data server-side from a web service that outputs in json format. I haven't found any good examples that don't use jquery and are server-side.
Specifically I'm looking at the "weight" field from this api:
have this site that has an api that can provide city name if I send my zip code as a parameter. http://www.postnummersok.se/api?q=16447the result is returned as a json object. Now i just want to read the result in my js function.I have tried the following but it always returns null:
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
foo({"1":"Jeff","2":"Mik","5":"Tom"});
I am using this code to get the output on the JSON form.
[Code]....
However, I must get the output only in simple JSON on the page without any HTML.
For eg: Here's the screenshot showing the source of the output page. [URL]
Notice that it has only the JSON string as the output.
And here's the screenshot showing the output page source (with HTML). [URL] .This HTML is what I have to remove. How can do I do this? The full code of menu.aspx.cs is putup here. [URL]
I'm using Json.NET and I'm trying to create a JSON string representing a row from a database table to return in an HTTP response. I'm not sure how to do this while I'm reading from the database.The problem is marked by the obnoxious comments /******** ********/
// connect to DB theSqlConnection.Open(); // open the connection SqlDataReader reader = sqlCommand.ExecuteReader();
System.Web.Script.Serialization.JavaScriptSerializer s = new System.Web.Script.Serialization.JavaScriptSerializer(); result = s.Deserialize<Hashtable>(data); Error is thrown if data is "{a:""test" 123",b:"hello" }" No error is thrown if data is "{a:"test 123",b:"hello" }"
How do I adjust the data string so that no error is thrown even when there are quotes?
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? Perhaps there's an attribute that I could decorate the enum definition, or object property, with?As an example:
I have some stored JSON strings stored in the DB which I want to return to the client as JsonResult . I know that Json(object) turns an object into JsonResult but what if I already have the result in a string ? can I cast it to JsonResult

I am using Json.Net however when I go to deserialize the following json I get that Json cannot deserialize to type List.
Json:

how to pass this via Json.Tried doing something like
var data = { Item1: "test", Item2: 5 }; var JSONdata = $.toJSON(data);
However that did not work. Although simply changing wcf to expect an object with two properties such as Item1 and Item2 will work. Here is example I'm using... I'll trim it a bit to make it easier to read:
function Post(data, url) { $.ajax({ type: 'POST',[code].....
So I'm writing an MVC application, and have a JsonResult post back to obtain some item information for scanned items on a warehouse application I am writing. I'm trying to obtain a URL query string value though, and cannot seem to obtain one via the normal 'Request.QueryString['variable']' way... Is there a way to do this? I also thought about just passing the parameter into my post, but I already have a single value on my jquery post, and I am unsure if I can tack on more values to this.
How do I bind a result from a JSON string to a dropdownlist (I have 2 fields), "NAAM" should be DataTextField and "CODE" should be the DataValueField. Using ddl.Items.Add doesn't do the trick.
this is the web method I'm using to convert my DataTable into JSON string:
[Code]....
But I'm not sure this is as good and as fast as it should be. I am sending to client side a JSON string format, but I think maybe there is a better way of doing this. I know there is JSON.NET
but I didn't see there any converting for DataTables.
I want to create a class with these properties so I can call a method for each record in our database and plug in the email, firstname, etc. I am having trouble with it because of the repetition of "property" each time. In other words, it doesn't fit the mold of this example I found:
Code: using System; using System.Web.Script.Serialization; public class MyDate { public int year;
We are trying to fill JqGrid in ASP.NET MVC3 application where datatype is set to 'jsonstring' and in it's action controller, we set the json data string in ViewData and retrieve the same in javascript function where we used it to fill the Jqgrid.
// Action code
[Code]....
// Javascript code to fill Jqgrid [Code]....
[Code]....
There is an error while filling grid and when i alert the data it shows " in place of " in data, as below.
The decodeURI function do not work on strData and it always show " in place of " in the data. We do not want to replace the " with " in a loop as it slow the page with large data.
