I need to write a webservice that returns multiple rows from a table. I am familiar with return of a single object.
I am calling a stored procedure in the webservice that populates a data table.
I guess I need to define an object collection to be returned. Should this be an array or can I return the data table itself?
I am trying to create a dynamic table that is being built based on the value of a search text box. The Table will have probably 6 columns of 20(max) rows.
My problem is I can't figure out how to return the data from the web-service to the JS function in a way that will allow me to extract the data that I need.
Here is the web-service method I have currently:

I tried it and it only returns the first table.

I have a web service that runs a query (from C#) to get a dataset from sql server. I get the following time out error. Googling on this error says, you can set the timeout on command object. But I am not using command object to set the timeout. This is the code I am using to get the dataset.

I have a datagrid control which is bound to a table which containing more than 1000 records. And i want to show only 25 records once a time. I have used paging in datagrid. But each time the next page index is set, query is fired again. This takes lots of time. So what is the easiest way to bound data in this case to improve performance.

I can fill and then return typed dataset from a web method, but applying these steps by using Typed Datatable instead of Typed Dataset I cannot return filled typed dataTable. So, is it possible to return typed dataTable from a web method? If yes, how can I do this?
I shall give a little bit information about my project. There is 3 project in my solution.
I) Presentation Layer (WinForm), II) Business Layer (Web Service) ,
III) Data Access Layer (Win form project type)... The problem is that;
I use 2 seperate methods. 1st is FillTable() which fill a datatable in my Typed Dataset in Data Access layer. The 2nd isGetTable() which should return typed datatable filled by FillTable() method. I try these methods and FillTable() methods (goes from I. layer to II. Layer and then III. layer) fills a datatable properly and after that I can return this datatable by calling GetTable() method from Typed Dataset (in III. layer) to WebService. I have tested the rows count of returning datatable and there is no problem up to WebService. But even after returning this typed datatable from WebService the table comes to Presentation Layer empty. So, there is a problem returning filled typed datatable from WebService to WebForm (from II. layer to I. layer).
On the other hand, if I try this methods by returning Typed Dataset instead of Typed Datatable, I can return properly with a filled datatable in Typed Dataset. But, I relly do not want to return a huge filled dataset which may contain 15 tables instead of one datatable. My questions;
1) Is there any logical approach mistake on my Layer Architecture?
2) What should I do in order to get a Typed Datatable from Web Service (II. Layer of my project)?

I know i've seen a tutorial for this, but can't locate it anymore. I have a class Employee in c# side, I also have a webservice where I pass in an ID# and an Employee object is returned. Now I want this object returned to Javascript code, I know I've seen it done before, can someone point me to a tutorial that shows something like this being done. I'm using the MicrosoftAjax.js file.
View 3 RepliesI 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?
So I've created a default Visual Studio project for a webservice and I invoked the HelloWorld method. What I get is indeed a "Hello World" string, but with some additional "crap" attached:
Code:

</style>
Where is this stuff generated? And how can I remove this.
I'm calling a web service called GetTooltip from inside Javascript. However, since the web service is called asynchronously, it doesn't wait until I get the return value from the web service, before it continues again. This is a bit of a problem for me, since the web service is in a for-loop. How do I make the Javascript wait until I hear back from the web service, before letting Javascript continue the for-loop?

vs2010, .NET 4.0I have a webmethod which I want to return a data record (for example: name, surename, address, age, zip etc)I wonder how to accomplish this. I think the solution is about creating an object which contains all the records serialized. And then the webmethod returns this serialized object. I'm not 100% sure how to accomplish this, if some of you good provide me with some tips, tutorial or link to an article explaining it, that would be great

I am stumped as to why it does not return rows?
