WCF / ASMX :: Cannot Return Typed Datatable From WebService
Jul 14, 2010
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 have a data library dll and first is it possible to use it in webservice forexample i call it as using DataLibrary; then in web method i will use it like
public boolean MethodName(int a) { if(DataLibrary.Method(a)) return true; else return false; }
and also i have to tell my all data connections are in DataLibrary.dll
my second question is i will use webservice to communucate with flash i will send flash a DataSet but flash cant read DataSet so i have give it as XML right?
so how could i change my following method which returns dataset to return xml ?
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 have a products table whereby I want to return a single row via a product id and use it as a data object.
I have used a .xsd dataset and a product class where I return a dataset and add the values into the product object that I created but I don't like having to write code like
"Product[0].ProductDescription" to get the product description. Is there a way of returning is straight as an object rather than a dataset?
I have datatable consist of 20 records and i want to bulk insert into sqlserver through the asmx webservice. Can anybody guide to me or provide Sample BusinessLogic and webservice code.
I have developed a web site that uses strongly typed datasets to access SQL. This has worked well: I have found that this is easy and robust, so that if I make changes to the data structure invariably I am either protected from this and my code continuesto work correctly, or there are compile errors that are obvious and easily fixed. Thus I am a fan of typed datasets.I am now starting to learn how to use web services, as I need to use the site's database with Windows programs. I have a web service with the following code, passing back a datatable: -
<WebMethod()> _ Public Function GDBSearch(arguments) As DataTable Dim tbGDBSearch As DataTable = taGDBSearch.GetData(arguments)
I am having a trouble while trying to create an entity with a custom view modeled create form. Below is my custom view model for Category Creation form.
[code]....
When i click on save button, it doesnt bind the category for me because of i am using custom view model and strongly typed html helpers like that
Okay, here's something that I could easily do the hard way and manually wire up each form element and save it to a datatable in memory, but there has to be a more efficient way to do it.
Here's what I have:
1. A strongly typed datatable and tableadapter in a XSD name Orders
2. A formview control which currently is connected to an ODS connected to the Orders tableadapter, this makes it easy to wire up the databindings for each form field in design view
I would like to:
- bind the the formview to an instance of the strongly typed datatable, and then save the dt to a session object without interacting with the actual database
- load forms on subsequent pages from the dt in session
- ultimately save the dt info to an actual database table on the third page
I've read some solutions where a custom class is created, but to me this seems like almost as much work as wiring up the form field to the table columns manually in code.
I have function called getdoctor () in asmx file I wannna call this webmethod from javascript and get the result into flat text i.e i wanna get the name doctor name not in neither in xml or json
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.
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
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:
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?
I am using PHP web service in dot net [URL]I set the name of web service as Test but when I am trying to access object test I was not able to use that, is there is any other method to use PHP webservice.
I was looking for an asp.net webservice that uses .net 4.0 but everytime I choose 4.0 the webservice choice goes away.Someone suggested to me that maybe they(MS) want you to use WCF instead. I don't know much about it but he said they are like webservices but better. So anyone got a comparisons guide?
I am trying to make a user control which has a gridview bound to a sql datasource.On the gridview user control, a user would select some fruits and press insert button and the user control would return a datatable/dataset of the selected items which then get databound to a gridview on the parent page. 1) I have made the user control with the gridview and buttons Included it on form and its working fine3) How to return a datatable from my user control and bind it with the parent page gridview?
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.
I have certificate(abcd.rar) , which I need to include when I call that web service from asp.net application, Some one tell me how do I implement certificate into my application, certificate is with file extention .rar
