I would like to manually send an HTTP 40x error code to client from a web method in c# asp.net web service.
Specifically I need to send 400 (Bad request) or 401 (Unauthorized).
I was thinking about the flow to look like:
if (a <= 0)
{
//send HTTP Error 400 - Bad request to client
return;
}
Is it possible? How?
we need to expose a web service to the 3rd party vendor which can only call using POST protocol, NOT SOAP.So my question, is it better to build a web service or just simply .aspx page?Also is there any best practice documentation on this.

View 1 RepliesMost WCF web service I have developed were consumed in a server side code (by adding a service reference in visual studio or creating a proxy class using svcutil.exe. I have never consumed a web service in a client code. So I apologize if I am using wrong terminology or my question does not make sense.We have a browser add-on or plugin that connect to a device on client computer (think of it as active-x control for internet explorer) inside a asp.net web page.This browser plugin/add-on then will be sending measurement data to the web server. After some research it appears to me that I can do eithera) Develop an AJAX enabled WCF web service and use script manager and javascript to consume it inside the web page that interact with browser pluginb) Develop a WCF web servcice (not sure about AJAX enable) that serialize request and response to JSON, and use JQuery inside asp.net page to consume it.QuestionWhat's difference between approach a) and b)? Which is better in particular scenario I have described.

I encouter some postback issue when using GetPostBackEventReference. Here is the Scenario:I have a javascript modal popup dialog and got a button in this modal dialog which used to select things (this is NOT an asp:button control)
When this javascript dialog HTML button is clicked, it will call the MS AJAX web service call by the javascript: eval() method. And this MS AJAX web service call is dynamically generated. So the code is like this:
var serviceCall = svcCall + "(" + parameters + ")"; //dynamically generate the MS AJAX web service call here
eval(serviceCall);
//use eval to trigger the MS AJAX web service call
As you may all know, after complete the MS AJAX web service, you can define a callback function to handle the completion:
function OnComplete(result, userContext, methodName) {
//force to call postback manually
eval($(userContext[0]).val()); [code]...
As you can see, this is how I bound the asp:button (i.e. btnSelectUser) 's Click Event to the asp:hiddenfield using the GetPostBackEventReference, and set the registerForEventValidation argument to false. I have also tried to use different ValidationGroup and set the CausesValidation to false.In summarize, I bound the asp:button's Click PostBackEventReference(i.e. __doPostback(....)) to the asp:hidden field's Value attribute, and using javascript eval() to eval this hidden field's value in order to manually trigger postback.
p.s. the btnSelectUser is an asp:button control and used to call out the javascript modal dialog.
Ok, here is the Problem:In the same page, there is some asp:validator, e.g. and , and of coz, when the page run into error, this validator and callout will display to the user. e.g. When the user didn't fill in anything and submit the form, the ValidatorCalloutExtender will display a ballon and tell the user. Imagine one of this ballon/validatorCalloutExtender come out and on top of your screen at the moment.
Then you click the btnSelectUser (asp:button) to show the javascript modal dialog, and in the dialog, you Add some users, and once you hit the SELECT button inside this modal dialog, a MS AJAX web service is trigger as mentioned above, and once this web service is complete, it eval() the asp:hidden field's value (i.e. __doPostback(...))......and do the postback manually.
However, because of the validatorCalloutExtender ballon has display, it somehow cannot trigger the postback in this way, but when I close the ballon/validatorCalloutExtender, the manual postback using eval() is just working fine. Even more strange is that, when the ballon is displayed, the first time I click the SELECT button inside this modal dialog it doesn't fire the postback, however, if I do the same thing again (i.e. open up the javascript dialog, and choose some users, then click the SELECT button again). It able to do the manual postback....and I don't understand why the first time doesn't work.
I have a website on the IIS but it has only the aspx file. Now I need to add the code behind for some pages. How do I go about this?
I've been trying to add the attribute "codebehind" and "autoeventwireup" on the top of the aspx file but no luck (the page_load event is not being called). Also, if I double click on the button from the design view in Visual Studio, it creates the javascript handle (not the server code).
I want to create a web method that accepts a List of custom objects (passed in via jQuery/JSON). When I run the website locally everything seems to work. jQuery and ASP.NET and everyone is happy. But when I put it on one of our servers it blows up. jQuery gets a 500 error after the ajax request with the response being:
System.InvalidOperationException: EditCustomObjects Web Service method name is not valid.
[WebMethod]
public void EditCustomObjects(int ID, List<CustomObject> CustomObjectList)
[code]...
I know that I can receive an javascript object from the server via ASP.NET AJAX using Json. But I am not sure how can I send an javascript object from my client-side javascript to my server-side code. And if I can, how can I extract this object in my server-side code and access its members?

View 2 RepliesI have built a WCF Service that is being consumed by a Silverlight app. At first I created one method that was very simple:
public String SfTest()
{
return "SF Test";
}
No poblem. My silverlight app references my service and displays "SF Test" in a textbox. Now I add a method to my wcf service like this:
public List<String> GetTest()
{
List<String> list = new List<string>();
String a = "a";
list.Add(a);
String b = "b";
list.Add(b);
return list;
}
I update the reference to the service in my Silverlight app and the using statement in my xaml cs page throws an error like the service doesn't even exist although it is there. I am assuming the problem has to do with datatypes or serialization or something like that but it is driving me up the wall. Why can't I consume a simple generic list in my Silverlight app through the WCF service.
I'm using Visual Studio 2008. I've added a control on a page but can't reference it in code-behind file. When I looked at the Code-Gen file, I didn't find my new control. It looks like Visual Studio didn't update Code Gen file to include my control. Is there a way to manually re-generate that Code Gen file?
View 1 RepliesI have code that populates 2 dropdownlist in a gridview. DropStart And DropEnd I want to add time values depending on a few things here's the routine I cal.
Code:
Public Sub GenerateTime(RowIndex As Integer)
Dim ComboStart As New DropDownList
Dim ComboEnd As New DropDownList
Dim ItemList As ListItem
Dim TimeInterval As Integer
Dim IntervalleCalcul As Integer
Dim NombreIntervalles As Integer
[code]....
now this code is called, and runs fine, it goes in the for loop and I see if I trace it that combostart and comboend both have 96 Items in them as expected. hence it did find the controls in the gridview. but when I exit this sub and continue the code by just running the code in the asp.net page the two corresponding dropdown control don't get the values that did get added in the code behind.
In the RowEditing is when I call this routine.
Code:
Private Sub GridDetails_RowEditing(sender As Object, e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles GridDetails.RowEditing
GridDetails.EditIndex = e.NewEditIndex
GridDetails.DataBind()
GenerateTime(GridDetails.EditIndex)
End Sub

I do not want to use HttpWebRequest class. It makes it hard to set up a request, does not allow to change host,
