Web Forms :: PageMethod/WebMethod Not Being Executed?
May 13, 2010
PageMethod which supposed to be called/executed when "onChange' of dropdownlist is triggered is Not being executed. I have 3 dropdownlist being created at runtime/dynamically inside a compositecontrol class and loaded (.dll) in a page at runtime. I have added a scriptmanager in the master page and set EnablePageMethods to true, tried placing the webmethod function outside of the compositecontrol and in the page, still webmethod is not being called... Anyone has idea or solution to this problem of mine? Or another approach to retain the selected value of the dropdownlist inside this compositecontrol (.dll) that is being loaded in a page at runtime?

I've read that OnClick is executed on the server and onClientClick is executed on the client. Is it better to use OnClientClick to do something like close a modal popup?
If my understanding is correct then this would avoid a trip to the server to accomplish the same task. This would be great for something that doesn't need to make a round trip to the server and back.

I have a service that works great on my development box. It uses JQuery to hit my web service, and then the JSON results are sent back.
The web service is located on our basePage.cs. We didn't want to put out an external WebService for this. Our on beta box something different is happening.
The web page seems to be trying to call the web method correctly - the JSON data is being sent... but the server doesn't seem to know it's a webmethod. here's my service function (it's in our basepage.cs which inherits from Page).

I want to render a user control in pagemethod and return the html back to client. But its getting annoying, I tried like many ways but nothing found working. The problem is that, the usercontrol require both HtmlHead and ScriptManager.
I tried this but it doesn't work(raise error : ScriptManger require in page) because ScriptManager must be inside HtmlForm but Page.Form always null.

I've reated a project containing 15 pages , (inculding one for logging in )well , i've noticed that actions located in the page_load function are not executed! (i've tested with changing the text of a label and a text box) and it's in all pages except the authentification page!i've read tht it's probably due to the DATETIME class used in pages. but is there any other explanation? or is there any way to fix the problem

I have a page which allows the user to send email. After they click the submit button, I display a confirmation message. However, if the user clicks the browser's Refresh button once the confirmation message is displayed, the email is sent a second time (or a third, fourth, fifth, etc.). What can I do to prevent the Refresh button from resending the email?

I have problem with user control: MyCollection : UserControl
MyCollection contains:
[code]....
Works fine unless I register event for some button:
button1.Click += ...
When click on button, nothing happens - page does postback, refresh but event handler method is not executed. Generated HTML is bit strange. Every page control has correctly generated ClientID including parent container ID.
Button in this collection MyCollection has odd ClientID - itemsAddresses$button1

I have some problem with the custom validtor, I do validate at both client side & server side, and i have noticed that the client side code has been executed when I clicked Submit..
More details:
The page contains some Text boxes & one submit button, and all is client-server validated, the problem that when the end user selects the file path through browse control, the code will auto-fill in the file name textbox, and it gives the option to edit; The code which is doing this in the custom validtor client handler, here is the problem it is on_submit click handler, the script function has been called again....!
I have no idea if this is the correct behavior, But I don't want the script code to be executed when any server events fired... !

I have a long running process that i kick off with a pagemethod that normally takes about an hour to complete, when it is finished it returns the result of the method.I then poll with another pagemethod to update the status of the first process.the process is taking 4.5 hours this week which is acceptable and understandable, but the feedback sometimes gives up after a couple of hours and sometimes the main method never returns any feedback to the client.
Regardless of the lack of status updates and final feedback the server still completes the long task.As far as i'm aware we have made no changes to any timeout values.is there a timeout setting that we are hitting that is above 1 hour for ajax methods?

I need to set a couple of Session vars by calling a PageMethod using jQuery.
The client side js looks like this:
function setSession(Amount, Item_nr) {
//alert(Amount + " " + Item_nr);
var args = {
amount: Amount, item_nr: Item_nr
}
//alert(JSON.stringify(passingArguments));
$.ajax({
type: "POST",
url: "buycredit.aspx/SetSession",
data: JSON.stringify(args),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function () {
alert('Success.');
},
error: function () {
alert("Fail");
}
});
}
and the server side like this:
[System.Web.Services.WebMethod(EnableSession = true)]
public static void SetSession(int amount, int item_nr)
{
HttpContext.Current.Session["amount"] = amount;
HttpContext.Current.Session["item_nr"] = item_nr;
}
only, it seems that the Session vars are not set. When I try to Response.Write out the Session vars, I get nothing. I get no errors, and I can alert out the values passed from the onclick event, to the js function, so they are there.

I have a pagemethod that saves data to my database. Initially I worked on editing an existing record. So I'd load a page by adding the FileNumber to the url:
Code:
[URL]
for example. Then on the click of my save button I send all the textbox ojects etc to a javascript function which then gets the values to save, and passes them to my pagemethod. I did this so I won't have to have refresh the page each time a user updates the file. ajxaified it in other word. Now whan creating a new record, I pass -1 as the fileNumber in my querystring. I do this so in my code, I will know it is a new record and I will write the required logic. However once the new file is created, I get the its primary key value by using SCOPE_IDENTITY(). then unless I refresh the page from my javascript function the url will remain
Code:
[URL]

I am using an AJAX.Net to call an ASP.Net PageMethod, which returns JSON serialized JSON data
{"d":"[{"Fromaddress":"testfrom1@test.com","Toaddress":"testto1@test.com"},{"Fromaddress":"testfrom2@test.com","Toaddress":"testto2@test.com"}]"}
The Response Header states the content type as
"Content-Type application/json; charset=utf-8"
However, the data is just available as a string, and does not seem to be available as JSON data from javascript. What do I need to do to work with the returned data as JSON from javascript?

I have a PageMethod that works perfectly well when it either (a) running in the VS dev server, or (b) deployed but marked with UseHttpGet=false.
What doesn't work, and is driving me mad, is having UseHttpGet=true and then deploying it to a test server (Vista & IIS7). It fails to call through the proxy with error code 404 coming back. But it works find if I set UseHttpGet=false.
I have gone through all of the basic stuff I can think to check, and as noted it works perfectly well on the dev box. So there must be something particular about full-blown IIS7 and its config that I am missing..
anything to check in the IIS manager that would cause this to fail? I've tried with forms authentication enabled and disabled, as a few posts mentioned issues with that.

I put my ScriptManger on the top level Masterpage with EnablePageMethods set to "true".2. I put a AutoCompleteExtender (AjaxToolkit) on a second level Masterpage which derives from the top level MasterPage. The AutoCompleteExtender is used for search with a TextBox. The PageMethod is defined in the Code Behind of this second level Masterpage.3. I have several Contentpages that derive from the second level Masterpage.Problem: The AutoCompleteExtender does not work and that's probably because the PageMethod is defined in the second level MasterPage in the CodeBehind and not in the Contentpage. Ok, so I'm pretty sure what causes the error,- I do not want to use a WebService, because I don't want the search to become public. And as far as I know you can't define a WebService that is only visible to the Website itself - it's always public.- It would be stupid to put the search on every Contentpage just for the PageMethods sake.

I have written an application that relies upon PageMethods. It was working fine in .NET 3.5 where I would rely upon exceptions to signify something failing during the call. I would then alert the user to what ever it was that happened. All was working great. I transitioned to .NET 4.0 as I am intrigued by the Parallel Computing improvements. Now any exception that I throw in the PageMethod in the code behind is met with an Unhandled Exception. Nothing has changed other than the target framework.
