Getting File From .ashx With A JQuery Post?
Jan 11, 2012This question is a following from another question I asked - Passing client data to server to create Excel or CSV File. I have a client page which builds a JSON object to send to the server, and I have server code which can parse that JSON object into an SQL command and end up with a dataset of required data.
I had originally been passing the JSON object to an .asmx web service which would return a JSON object containing my data. Now I want to go in a different direction and have the data returned as a .csv file.
I understand I can try to put my JSON object into a query string and call my .ashx page, but the JSON object could get large, so I'm trying to use the Request.Form of a POST.
My question, and lack of understanding, is in how to use jQuery to post to the .ashx page and have it return the .csv file to the client. If I navigate to the .ashx page directly (and modify the page to hard code the passed data), I get the .csv file returned to me no problem (i.e I get the prompt to open/save the file). If I make a POST to the .ashx file from jQuery and send my JSON object through, I get a response which contains the data in a string, rather than getting a .csv.
So, is there something I am missing, or am I just trying to achieve something that I can't or shouldn't be doing? I'd thought about passing my JSON object to a .asmx web service which would store the JSON object into a database and return an ID, and then use window.location to browse to the .ashx with the ID as a query string parameter to then generate the .csv file, but I thought there might be a way to avoid that middle step and do it with the POST.
Asp.net Mvc - Post Code Being Triggered On JQuery Load?
Jan 13, 2010I have the following functions in my ProceduresControlller:
Function Add(ByVal bpid As Integer) As ActionResult
Return View(GetAvailableProcedures(bpid))
End Function[code].....
I'm loading the Add dialog via jQuery like so:
$("#dialog").load(
"/Procedures/Add",
{ bpid: 123 }[code]....
This is failing because it's calling the Post method (where "covered" can't be empty) instead of the Get. I tried decorating the Get with <AcceptVerbs(HttpVerbs.Get)>, but it doesn't change the outcome.how do I get it to use the Get? I realize I could change the names to not be ambiguous, but I want to know why it won't pick the Get if I'm only passing "bpid".
Jquery - Ajax Post Method Not Working?
Dec 20, 2010I am using jquery so using ajax to post data, but for some reason when i click on submit, the page doesnt go from aspx to aspx.vb on the back side.here's my code -
$(document).ready(function() {
$("#btnsave").click(function() {
var firstname = $("#" + '<%=firstname.ClientID%>').val();
$.ajax({
[code]....
new_class is my webmethod in the vb.net side. Now if i put an alert in the btnsave onclick function, i see the firstname value in the alert. But the page does not call the new_class function after that.

Jquery - Post Table Rows, Added Via Javascript To The Server In ASP.NET?
Oct 3, 2011Access <asp:table> table rows added by javascript in asp.net webform . Apologies for the duplicate question but I'd really like an explanation why this is the case. It is probably due to my lack of understanding on how browsers process HTML tables on submission to the server.If I have a <HTML> table or an <asp:table> control on an aspx page and I add rows to it client-side using JQuery / Javascript, why can I not include these added rows in a post-back to the server?
I've been trying to get this to work and it looks like I can't do it based on the answer to the previous question. But can someone explain why this is the case? The table itself can be returned in the post-back but the only rows present are the rows that were part of the table when it was sent to the browser originally - it does not include the rows added by the browser.there was a way to include these new rows in the post-back, the same as any client-side user input?

View 2 RepliesC# - Map A Virtual Directory For *.asmx Methods In ASP.Net 2.0?
Jun 7, 2012A little while ago, I managed to get WebServices to return JSON as well as XML from the code-behind of an ASPX.
Today, I needed to migrate an existing ASMX WebService to return JSON instead of XML (which was accomplished with little fuss). My problem became evident in testing the new method.
In the code-behind for the ASMX, I created a new method to return JSON instead of XML. The method works, in that it returns the expected JSON however the new routine breaks every XML-returning method in the code-behind (they all throw "System.NotSupportedException: The type System.Collections.Hashtable is not supported because it implements IDictionary." which is unexpected because the return types are all defined as XmlDocument).
If I simply comment out the JSON-returning method, the XML-returning methods function normally. Uncommenting out the JSON-returning method breaks the XML-returning methods again.
While I cannot find any supporting documentation anywhere, this behavior leads me to believe that in ASP.Net 2.0, JSON-returning methods cannot co-exist in the same module as XML-returning methods.
This led me to try separating the methods in sub-classes like so:
<WebService(Namespace:="http://tempura.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<ScriptService()> _
[Code]....
Javascript - Return JSON From ASP.NET .asmx?

Even with the ResponseFormat attribute added the response is still being returned as XML rather than JSON.

Asmx Asp.net Webservice Return Multiple Classes Wsdl?
Aug 18, 2011We are developing a webservice for a client. We are not supose to throw SoapExceptions, so instead, we catch every exception server side, and return a custom Exception class.
Public Class Order
...
End Class
[Code]....
The problem now is, that since my webmethod is returning the type [Object]. The wdsl that is generated does not contain the order, or the exception.
I can change the [Object] to [Order] Or [MyException], but only one of them is generated in the wsdl.
I want both the MyException type and the Order type in my wsdl, but i just cant get it working.

Pass Generic Type Definition To Asmx Webservice?
Feb 8, 2012I use jQuery ajax calls to ASP.Net web services (ASMX files) to update the web page data.
I have the database storing code seperate from the domain object class code (in the example code below, there is an Animal class and an AnimalRepository class). I'm implememting a convention that all similar domain object repository classes will have a Store method .
I would like to create a web service that can cater for calling the Store method for any one of these repository classes. To get this to work, in the below code sample, the List(Of Animal) parameter would need to be a generic type.[code]...

Are There Any Tools To Build ASMX Proxies From Server Side Assemblies
Aug 21, 2009We have a set of assemblies which implement web services operations.To build the client proxies, we first build and deploy the web services (assemblies and ASMX files) on the server.Then we use wsdl.exe to point to the ASMX endpoints and generate the classes for the client proxies.I've seen that it is possible to create the proxies from wsdl files (instead of asmx endpoints) using wsdl.exe or disco.exe.Is there a tool to generate wsdl files or event better proxy classes directly from the server assemblies without the need to use a web server?
1) This is a somewhat large project that has been in development for over a couple of years now. The decision to use ASMX web services was made before the existence of WCF.
2) I already thought about writing our own proxy generator and that may be an option if we don't find a tool that does it.
3) We still want to bind to the WSDL contract. What I'm trying to avoid is having a dependency on a web server during the build process.
4) We already auto-generate the proxies in our automated build which runs in TFS Build and that has not been an issue per se. The issue, as I was told, is having to split the build in two parts: server & client. There may be alternatives to avoid the split using some fancy MSBUILD task, but my knowledge on that matter is limited.
5) I do expect the build to brake on TFS Build if the client side code and server side code don't match during compilation. That should have been addressed on the developer's machine before check-in.
6) We have strict control over the server and the client parts. This set of web services serve as a back-end to a Click Once Windows Forms application. Everything runs on an intranet. Every time the contract changes, it is done in tandem with a new version of the client application.
7) WCF is not an option in the short term for this set of web services. When I joined the project over a year ago I was given the task of creating a new set of web services for interoperability with other internal systems. Those web services were designed upfront to be easily upgradable to WCF once upper management allowed us to use WCF. I'll have to take a look into svcutil.exe, but if it does what we need, I'll have another point in trying to convince upper management to adopt WCF.
System.Data.SqlTypes Datatypes Be Used In Asmx-style .NET Web Services?
May 26, 2010It looks like they are converted to regular date types in the generated proxy object.I'd like to optionally pass null values for these dates.Other than switching to WCF (no time to learn it right now), what is the best way to handle this situation. It looks like I also cannot pass NULLABLE date types.
View 1 RepliesUnable To Use IntPtr (WindowsIdentity Token) As Input Param On WebMethod (ASMX Web Service)?
Jun 26, 2009We're in a strange situation with a legacy winforms VB.NET 1.1 application using ASMX web services. Trying to send a user Token from a WindowsIdentity object as a parameter to a WebMethod. I will be adding a 'HACK: comment. System.Security.Principal.WindowsIdentity.GetCurrent().Token
The token is of type IntPtr, the first problem is the WSDL being generated doesn't support IntPtr with the error of 'unsupported type'I'm aware this is a big WTF question and sounds insecure, so any simple helpful alternatives are welcome but there are a lot of constraints on how we can change this system, including complications with the hosting environment. So I would just like to get our piece of data over to the web service to save a lot of other headaches.
