AJAX :: Passing Return Value From A Web Service To A Label In A Form View?
Mar 17, 2010
I am using JavaScript to call a web service. The JS is correctly receiving and passing the web service information.
At the moment, the web service returns a country name as a string to a JavaScript alert pop up box as follows:
[Code]....
I want to change this so that web service returns the country name to a label inside an insert item template of a form view.
Is there a way to pass in the label variable to the OnComplete function signature and still account for the variable args?, such as:
[Code]....

Seems like there are a lot of ways to solve this problem.
Currently I make a partial view with a form like so:
[code]....
What are other ways to accomplish the same thing and what are the pros and cons vs what I am doing?
Is Ajax.Form useful?

js:
[code]....
I put a break point inside MyWebMethod. When I invoke this call on the page, the break point never gets hit. It works fine when I remove all parameters from MyWebMethod's signature and pass in '{}' from JS as parameters. Once I try to pass in a string parameter, it stops working.

I have site that I need to have a vendor send an Http Post to us, using querystring parameters, then I have to look up some data and return a few results and parameters back to them. Can this be done using CLASSIC ASP? I ask this because I am still in a learning phase with .NET and have limited resources available to set up a web service.

I just hit the following issue: I am calling a web service that returns a serialized JSON object let's say: __type, FirstName, LastName (.net object Person with properties FirstName and LastName). __type's value is Test.Person
I have created a JS object using Type.registerNameSpace/registerClass called Demo.Person and it is registered on the page using the ScriptManager. Everything is working fine; I am able to get data from the server on the call back.
Is it possible to make the returned object from the web service be an instance of the declared JavaScript Demo.Person class? The idea would be to call a method like result.getFullName() on the client side without having to copy all the properties. This is just a simple scenario for more complex objects.

I need to perform asp.net web-service function call via jQuery and pass asp.net application path to it. That's the way I'm trying to do it (code is located within asp.net page, e.g. aspx file):
[code]...
Function call works well, but applicationPath parameter doesn't passed correctly. When I debug it I see that backslashes are removed, function gets "C:ProjectsSamplesmytestwebsite" instead of "'C:ProjectsSamplesmytestwebsite'".

I have an UpdatePanel with a button and a label. Inside the button click event I call a web service which returns a string. I then want to append that to the label. Simple! Except that it doesn't work. I can change the label to a value I set inside the click event but when I try to add the web service string it doesn't work.
I have been trying to override the PreRender event, to use a ViewState, to set EnableViewState on the Label to be false. Nothing. Works. At All. If I set a break point inside the OnPreRender override I can see that lbl1.Text is being set to the value that I want (i.e. the value from the web service) but it doesn't appear on the browser.

I have a form that I don't want to post back so I need to get the form values into my controller via jquery's ajax method.Here is my test controller method:
[Code]....
When I debug the controller method and look at the lineItems parameter, it always contains 0 items. I've tried various formats for the javascipt lineItems parameter but still 0 items. I'm also open to some other way of getting these values in like the jquery form serialze method or something else.

we have console-hosted WCF Service and ASP.NET WEB Service (on IIS).
After some tough operation WCF Service must return some data(large data) to ASP.NET Web Service for next processing. I tested on small results - everything is ok.
But after testing on real data(serialized result object is near 4.5 mb) error occurs on ASP.NET Web Service (which is client in wcf-client-server communication).
Messages size are configured by next binding (on server and client):
NetTcpBinding netTcpBinding = new NetTcpBinding();
netTcpBinding.TransactionFlow = true;
netTcpBinding.SendTimeout = new TimeSpan(0, 4,0, 0);
netTcpBinding.Security.Mode = SecurityMode.None;

I have set up the Auto complete control and the web service to populate it, this web service resides within the project that uses it, it works fine on my machine (if I had a nickel for every time I heard that from a developer...) , but when I install it on Dev, the site asks for authentication, then when I select the tab with the textbox that has the Auto Complete control, it asks me for authentication again. If I remove the Auto Complete control, it no longer asks me. The funny thing is, I can enter authentication info OR just click cancel and the web service works fine.
In the IIS site on Dev and in the Web config, I have turned off authentication (in IIS I use anonymous and in the Web.config, I set it to "none") My development machine is in a domain, for some reason beyond my control, both Dev and Prod are not in a domain; both Dev and Prod machines are Server 2008. how to prevent this authentication form from showing???

I have a view which takes two objects: booking and list of reasons for canceling that booking.I have two classes: clsBooking, clsBookingCancelationReason I can read both objects in my view - no problems there. After I read the objects, I display the booking details and I generate a list of cancelation reasons in the following way:
[Code]....
The code above generates a list of cancelation reasons.How do I pick up the selected ReasonId from the list?
I need to generate a link that will contain the bookingId and the selected reason for canceling the booking.I can get the bookingId out easily since it's stored in the Model...but how do I go about the selected ReasonId?

I am trying to implement an ajax form inside of a jquery ui dialog.
I have a view with a button that opens the modal dialog form, makes an ajax call to an action that loads a partial view into the dialog. The partial view consists of a form created via Ajax.begin form. When I post the form I close the modal and update a div on my main page. This all works fine.
The problem is, the next time I open the modal and submit the form the http POST for the form is called twice. The third time I open/submit the form is submitted 3 times and so on...
It seems as if the submit button/form is bound multiple times and I cant figure out how to fix this.
Here is my code...
first the jquery call to load the ajax form partial view and create the modal...
[Code]....
here is the ajax form partial view...
[Code]....
and the js callback when the form is submitted

I have the following ActionResult() method:
[Code]....
The method is called once the <form> is submitted. If the validation is good, it moves on to create a new user Once the new user is created, I want to redirect the user to a "ThankYou" page passing along the newly created user (object). The TempData["User"] trick seems to work like a charm! Then inside my ThankYou ActionResult() I do the following:
[Code]....
The problem I have is once the user has been redirected to the "ThankYou" page. If he decides to refresh (F5) his browser, the value in the TempData is lost.
What are my possibilities to overcome this issue?
Instead of passing an entire object to my "ThankYou" page, I initially thought of passing the ID of the newly created user and re-query my database to get the object.
The only problem is that the ID will be seen in the QueryString allowing the user to simply change the ID value and try to find other users...
Is my only other alternative to simply place the user object inside a Session? Is that my only other option?

In my website I have two forms: parent form and child form(dialog box). Their expected behaviour is like this: if clicked on 'show' button on parent form, a dialog form opens that displays a gridview. In dialog form, if clicked on 'select' button it closes
itself and returns value in selected row back to parent form.
To achieve this I write following code (.cs) : in parent form:
void ShowBtn_Click(object sender, EventArgs e)
{
StringBuilder jScript = new StringBuilder(); [code]....
Now problem is: the code in parent .cs works fine, it opens the dialog properly. But when clicked on 'select', instead of returning back to parent, it opens the same dialog again in new window. This newly open window says "Done but error on page" at left bottom.

I am calling a WebMethod from this code:
if($(this).attr("checked")) {
..
MyWebMethod(variable1, variable2, onSuccessFunction);
}
The MyWebMethod returns an integer, and I want to set $(this).attr("id") of the jQuery object above to the returned integer. Basically, I'm trying to do the equivalent of an MVC Ajax.ActionLink...AjaxOptions {UpdateTargetID =...} However, I can't figure out how to get both a reference to $(this) as well as the returned value. For example, if I do:
MyWebMethod(variable1, variable2, onSuccessFunction($(this)));
I can succesfully manipulate the jQuery object, but obviously it doesn't have the return value from the MyWebMethod. Alternatively, the first code block with a method signature of onSuccessFunction(returnValue) has the correct return value from MyWebMethod, but no concept of the jQuery object I'm looking for. Am I going about this all wrong?
