how to send large dataset over web service..
i want to get data from my database and dispaly it in my web page using json with webservicei'm going to post my code i create a webservice and add method which return string to get all data so my code like this

and in my page

I have been trying for two months to get this code working, and I am close, but still confused. I want the JQuery UI Autocomplete function to call an web service which returns JSON data and display that data for selection, and on selection put the selected value into a hidden field.
There are several issues:
1) The autocomplete function is not firing
2) The source: "/AutoSuggest.asmx/DOTFind?" line throws an invalid object exception
3) The service requires two parameters: (string prefixText, int count) - count tells it how many records to return.
4) I am not at all certain that this code will accept JSON data that comes back from the service
Here is the code:

I have a webservice which retrieves data from another external service. The data is already in JSON Format. So I retrieve it and set it to the return value (type: string) of my webservice. But according to firebug the webservice then encapsulates the provided JSON-Data with a backslash, e.g. it returns:
[Code]....
instead of
[Code]....
But the JSON provided by the external service is correct. So how could I provide the correct string to jTemplate from my Webservice?
I try lots. we can bind asp.net gridview many ways but datalist i not able to bind. How can I bind asp.net datalist using jquery/json and webservice.
View 1 RepliesActually I am trying to learn jQuery Ajax calls to asp.Net webservices.
I have been trying to call the webmethod below:
[code]....
Do I need to serialize my object in some way before setting the 'data' attribute, so that I can call $.ajax() function?
I have an ASP.NET webservice method that returns a generics list (List'<'Construct>) serialized as JSON, using code such as this:
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
public class TestService : System.Web.Services.WebService {
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string GetOccupationListJSON(int SOCLevel)
{
Construct NewConstructList = new ConstructList();
DataContractJsonSerializer serializer = new DataContractJsonSerializer(ConstructList.GetType());
MemoryStream ms = new MemoryStream();
[Code]....
I assumed (from looking elsewhere) that accessing the JSON data through the index would provide me with access to the underlying object at that index, so that I can then work with it to access its properties.
However, when i=0 and I do var Construct = data[i]; I get the character at the i position of the data array ([), and in the next iteration I get the second character ({). So clearly I am accessing the elements of a string array rather than the JSON data object.How do I make sure that the data returned by the webservice gets into proper JSON format, so that I can iterate through the object elements within it?
I have two parameters (categoryName and categoryDescription) that I need to pass to the web service using JSON. I found the syntax to pass categoryName but have not been able to get the correct syntax to pass both parameters. Here is the code.
<script src="js/jquery-1.4.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() {

I have successfully returned data from a ASP.Net webservice in JSON format (using a service method that required no parameters) but have struggled with making a webservice call that requires a parameter.
Webservice:

Public Function TestWebService(ByVal Description As String) As Stock
Dim res As New Stock(Guid.NewGuid, Description)
Return res

View 3 RepliesI'm having an issue sending large volumes of emails out from an ASP.Net application. I won't post the code, but instead explain what's going on. The code should send emails to 4000 recipients but seems to stall at 385/387.
The code creates the content for the email in a string.
It then selects a list of email address to send to.
Looping through the data via a datareader it picks out the email address and sends an email.
The email sending is done by a separate method which can handle failures and returns it's outcome.
As each record is sent I produce an XML node in an XML document to log each specific attempt to send.
The loop seems to end prematurely and the XML document is saved to disk.
Now I know the code works. I have run it locally using the same SMTP machine and it worked fine with 500 records. Granted there was less content, but I can't see how that would make any difference.
I don't think the page itself times out, but even if it did, I was sure .Net would continue processing the page, even if the user saw a page time out error.
I have an RSS-reader in one of my webservices. I then utilize the webservice using javascript and everything works fine with small to moderately sized RSS-feeds.
But the webservice keeps timing out when I'm trying to use larger RSS-feeds.
ie. this feed from Youtube: [URL]
Javascript
VideoModule = {
LoadVideos: function () {
var ret = RSSService.GetFeed("http://gdata.youtube.com/feeds/base/users/TheOnion/uploads?alt=rss&

I am building a webservice that reads some HTML source code from a website and sends it back to the client. The service however is failing to send the data because it is too large. I keep getting this error:
The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter [URL]..... The InnerException message was 'There was an error deserializing the object of type iRacingForumServiceTest.ForumService.GetForumListResponseBody. The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Line 153, position 247.'. Please see InnerException for more details.
I have been googling this problem for ages and I cannot figure out how to apply the answers I keep finding.
The problem is simple: the default configuration doesn't allow such large strings. I just don't know how to change this. All I keep finding is things related to WCF, I'm not sure if that applies for me.
What I keep finding is that I need to change the web.config file in various ways. However I cannot figure out where I need to put the config sections. I've tried everything but without a complete web.config file example I can't get it to work
Here is my current web.config of the server:
Code:
<?xml version="1.0"?>
<configuration>
<configSections>
</configSections>
<connectionStrings/>
<system.web>
[Code] ....
I found this piece to add to it:
Code:
<system.serviceModel>
<services>
<service name="ForumService">
<endpoint address=""
binding="basicHttpBinding"
[Code] ....
I figured out where to put it without getting errors (just as a child of the <configuration> element), but it just doesn't work. I get the same error no matter what values I try here... This shouldn't be such a difficult issue, how can I solve it?
[code]....
What's wrong?
Edit: And what if I need to return {Message:'',Type:1} ?
Edit2: The answer for the last one is: I can return a Dictionary<string, string>
Does anyone know of free webservice that returns a list in the form of JSON? I have searched many webservice sites but they all return xml. Geonames.org is not required.
View 3 RepliesI was looking for JQuery Grid which will help me more than 1000 - 2000 records. I mainly need search and paging . Can some tell me with its own experience
View 3 RepliesThe main issue is that I cannot run a webservice that accepts requests in JSON format. I keep getting a 500 Server error stating that the "request format is invalid." My ASP.NET AJAX extensions are installed. My server is running Plesk Control Panel 8.6 which is undoubtedly causing these problems.
The default handler for this specified extension is shown in the web.config like so:
For my applications webservice to handle JSON it needs to have this reference:
<add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
Plesk is not allowing the request to be handled properly. I need to know the correct http directive(s) to put into the web.config to properly handle JSON webservices.
I have trouble with JSON response compression. I look to response headers after uploading website to production server (Windows 2008, IIS 7) and found uncompressed response. Turning on "Enabled static compression" and ""Enable dynamic compression" in IIS control panel does not effect. ASPX pages was responsed gzipped, but webservice response uncompressed.
I looked to google, but no answer found about this trouble. Also, I try this [URL] way (and adding to web.config this module) - but this source is excellent working at development machine with ASP.NET development server (and have seven times response size reduced) and totally ignored at IIS7.
How I can apply gzip compression to json responses from my webservice?
I need to make a call to a json webservice from C# Asp.net. The service returns a json object and the json data that the webservice wants look like this:
"data" : "my data"
This is what I've come up with but I can't understand how I add the data to my request and send it and then parse the json data that I get back.
string data = "test";
Uri address = new Uri("http://localhost/Service.svc/json");
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(address);
request.Method = "POST";
request.ContentType = "application/json; charset=utf-8";
string postData = "{"data":"" + data + ""}";
How can I add my json data to my request and then parse the response?
I am trying to solve a problem that involves creating a very large XML string and stream that to browser. Right now i am using stringbuilder class. Here is the sample code
here i am using only just one property.
[code]....
total length of the final string will be 120MB or so.
With this code i am getting out of memory errors intermittently. To resolve this issue ..i am planning to create a HTTP handler for streaming XML output to browser.
I have a website where I am using the JSON webservice. I have uploaded my website on the server.
Problem:
When I try to access the webservice it gives me the error as shown in below screenshot. In the below screenshot MyServices is my webservice. MyServices.asmx is the name of the file that I am trying to access.
Troubleshooting that already has been done:
I tried cleaning the bin folder and rebuilding again. But it didnt work.

But when there is large amount of data, it's not working
I have a simple webservice that I would like to upload a file to. The problem is that I need the response in json.
Form my experience in order to get a response in Json my request has to have a content-type of 'application/json'. But ofcourse this cannot be the case with a file upload since the content type will have to be 'multipart/form-data'.
In my Json i want to return a value showing whether successful and a filename.
