Thank you for your response. But still ADO.NET is missing

Useful links. Thank you! I'm going to try now..

The above code is correct & the data which I sent was wrong. Thank you for the solution

After creating dictionary how to post it? Please check the following.

Dictionary<string, string=""> array = new Dictionary<string, string="">();

array.Add("ael_id", "53198");
array.Add("state", "1");
array.Add("comment", "All is good'");

string data = JsonConvert.SerializeObject(array);

var dataToSend = Encoding.UTF8.GetBytes(data);
var req = HttpWebRequest.Create(uri);

req.ContentType = "application/json";
req.ContentLength = dataToSend.Length;
req.Method = "POST";
req.GetRequestStream().Write(dataToSend, 0, dataToSend.Length);

response = req.GetResponse() as HttpWebResponse;

Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();
Console.WriteLine(responseFromServer);



I got Internal server Error. The problem is in req.GetResponse(). Where am I going wrong?

Thank you for your reply

Thank you for your help! As I'm receiving huge json dataset from a webmethod in asp.net, I want to store the data in different tables of sql server db. I want to parse it from asp.net or else from sql server. Your help is appreciated! Thank you!

The dropdownlist is filled dynamically & I know to access it in Javascript. But in code behind, i know to take the selected value. But I don't know to access ALL the items of the dropdownlist. So, I need help. Once I know to access all the items then, I can put it in the table.

Could you tell me the code to take the value (not selected value) from dropdownlist?

Sorry I want the other way. I don't want dropdownlist to be filled. I want the all the values of dropdownlist to be stored in DB

yes, Items are added, from that I'm selecting too. But in code behind I'm getting that 'null' problem.

I've updated my question by including the code.

I've updated my question by including the code.

I've updated my question by including the code.

dropdownlist.SelectedItem.Text gives me "System.NullReferenceException: Object reference not set to an instance of an object"

In aspx file
I call the session by
string a = Session["sessionName"].toString();

For this I got only null value. But when I included the following code in Web.Config, it works well.


<configuration>
<system.web>
<sessionstate mode="InProc" cookieless="true">

Thankx sameer8k! problem solved for me!

By the way the logic I used is working well. I'll surely use Update Progress in future. Thank you so much!

I'm new development!I think Update progress is a Ajax tool. As I'm working in Visual Studio Framework 2.0, I could not install ajax.

Thank u
But I used simple logic of using div,& inside that div, put the loading... image.

then on button click call
$("#divId").show();

and body, onload
$("#divId").hide();

on button click, I'm getting response from a web method. It takes few seconds. During that time I want to show the loading image on the same page

it's not Ajax

how to implement this? Till I get response from the server I want to show the image & then hide it.

But it's redirecting to an intermediate page. Instead I want to show/ hide the image in the same page.

you are most welcome!

I didn't refer the jQuery file. Now it's working well. Thank u

@Tadit Dash
Sorry as I'm new to JQuery, I could not get it.
For example can
document.writeln("aaaaaaaa");
be written as
<script>$('#userName').text('aaaaaaaa');
if I want to write in tha span with id="userName"? BY doing so I didn't get the result as expected...
Pl, clarify! thankx

Thank you for the solution. But I could not include namespace of JavaScriptSerializer (ie.,I'm unable to add 'using system.web.script.serialization'. I searched for it's dll & I could not find it)Could you please help.

I'm getting this Json array as result from a RESTful web method. The JSON array is as follows
{"response_list":[{"id_country":"302","label":"NICARAGUA"},{"id_country":"303","label":"NIGER"},{"id_country":"304","label":"NIG\u00c9RIA"},{"id_country":"305","label":"NIU\u00c9"},{"id_country":"306","label":"NORFOLK, \u00ceLE"},{"id_country":"307","label":"NORV\u00c8GE"},{"id_country":"308","label":"NOUVELLE-CAL\u00c9DONIE"},{"id_country":"341","label":"SAINT-VINCENT-ET-LES GRENADINES"},{"id_country":"342","label":"SALOMON, \u00ceLES"},{"id_country":"343","label":"SAMOA"},{"id_country":"344","label":"SAMOA AM\u00c9RICAINES"},],"response_status":{"message":"Success","status":0}}
I need to take the "label" & populate in a dropdown list. This is what I mean by handling JSON multi dimensional array.

Thank you, but I want to handle JSON ARRAY. Please help
