In our application we have a scenario where we need to display a panel using modalpopupextender after performing an async call on the server. We were using the Show method for displaying the popup. It used to work fine without any async call. But when an async call was introduced during the request processing the popup is not getting displayed.
View 7 RepliesWhen displaying a Popup using the ModalPopupExtender it makes all the textboxes read only - is there a way to prevent people clicking on buttons behined the popup? I have 2 butttons plus another button in a gridview and i would like to disable them when the popup is displaying.
View 6 RepliesI want to make an async call to the server when an achor tag is clicked and then have the browser advance to the href without waiting for the async call to return a result. I am using System.Web.UI.ICallbackEventHandler. My server code is not executing. The server code only executes if the GetCallbackEventReference call specifies a clientscript value which means the page has to wait before advancing. What am i doing wrong?
My client code is:
<script type="text/javascript">
function ReceiveServerData(arg, context) {
}
function DoAsyncTask(arg)
{
CallServer(arg, '');
return false;
}
</script>
Since data saving is a time consuming, I would like to call data saving method using Ajax and that too Async what i mean is as soon as the user click submit button it just display the confirmation page and data saving bit keeps going on in the background.
Is this possible using Ajax tool kit?
How do force full page rendering in async call process?
[Code]....
I know this is a pretty common issue as i have read a lot of posts from people with similar issues. However thus far what i have uncovered doesn't seem to help resolve my issue. I have used the ModalPopupExtender regular enough but this is my first time needing the Dynamic side of things. The code I have is very basic and generic at the minute..I have the following ASPX code in place:
[Code]....
Now just to say at this stage the Modal Dialog box pops up and closes 100%. So my ProductPopulate.asmx service at the moment for testing is just using the VS2010 default Web Service with a few changes that i will explain.
[Code]....
So the changes i have made to the default VS2010 webservice is from this article http://sandblogaspnet.blogspot.com/2009/07/working-with-modal-popup-extender.html
I changed the default HelloWorld method to static and also uncommented the following line
[Code]....
So this is as far as my code has gotten at the minute. The Modal Dialog pops up 100% and what i would expect to see within the dialog box would be the text "Sampling Control" from the DynamicContextKey. Instead what i get is the "Web Service call failed: 500" error. I have stripped everything back to basics as you can see.. but for some reason i am still getting this error. I have used Web Services before from time to time without any issues and i have used the ModalPopupExtender without any issues.. but i am left scratching my head as to what i am missing on putting the two together.
Also just to note, both ASMX and ASPX files are currently in the root of the web project to rule out any path issues. Also i am using the VS Web Service to preview and debug.
On one of my pages I've got a popup window implemented using the ModalPopupExtender. The content html of the popup is retrieved from a webservice dynamically (using DynamicServicePath, DynamicServiceMethod properties of the extender). Everything works fine, however there is a minor problem: web service call takes about 2 seconds and the popup panel is blank during this time, which confuses the users. I would like to display 'Loading...' message in the popup window (or an animated image, does not really matter) during the webservice call. Is there a way to do it?

how to use the value of 'duplicate' in btnsunmit_click() from webmethod.
I have a MVC project in a test environment with an AsyncController. I have a pair of methods, ...Async and ...Completed and it seems to work well.The thing is that I've seen examples where the Async method has arguments such as....
public void IndexAsync(AsyncCallback callback, object state)
In my project that defintion yields "No parameterless constructor defined for this object." When I remove the arguments like this...
public void IndexAsync()
it runs fine. I'd like to explore some examples that use these arguments. Where do they come from? How can I get them...
I have a simple web page in ASP.NET / C#. Currently to fully render the data I require calling a block of code that runs on background threads and can take multiple minutes to complete. I've got it to the point (using the async attribute on the page declaration) to execute and return fine with the html once it's done. What I'd like it to do is allow me to return immediately with a 'loading page' of some sort and then have that page be updated when the background work has been completed. Right now I get nothing on the page while the background work is being processed.
View 3 RepliesFor example, I am using wenclient.DownloadfileAsync to download a file asynchronously.
In the DownloadFileCompleted event handler, I can check if I have any exception or not by using AsyncCompletedEventArgs.Error property.
If I re-throw this exception, however my executable is stopping running immediately.
I am wondering how to handle this kind of exeception? How to pass this exception back to the
calling thread?
My javascript code is calling a asp.net webservice, so i have a call to the webservice something like this:MyWebservice.GetData(param, ResponseReceived, ResponseTimeOut, ResponseError);When the webservice returns data, ResponseReceived method is called.However sometimes the user might navigate to another url before the webservice call actually returns, in such a scenario FireFox throws an Error saying 'An error occured oricessubg the request. The server method GetData failed'So my question is how can i kill the async call when the user navigates to another page or makes another request to the webservice? I know in a normal XMLHttpRequest i could have called Abort method, but not sure how to make it work with the above webservice proxy.

View 3 RepliesThis thread is more about learning, actually I have a web service which just returns string. I have been calling this service from code behind and updating lable with the string received from the web service.
Now I want to call web service using JavaScript. As far as I know, I have to add <asp:ScriptManager..../>. Second I have to add [ScriptService] to the web service.
But I don't wat to add <asp:ScriptManager..../> and [ScriptService].
Is there any way to call web service using javascript without adding <asp:ScriptManager..../> and [ScriptService]
Also, I am kind of lost in SOAP, JSON. I am not getting where I actually use SOAP, JSON. Using <asp:ScripManager../> and [ScriptService], I actually didn't see use of SOAP, JSON.

Can I call Ajax.BeginFrom from a custom helper method ?
AjaxHelper is not available in a custom helper method, so I tried to pass the "Ajax" available in ViewPage to Helper method while calling it, but then in method, BeginForm is not available on that passed "Ajax" parameter.
I am using VS 2008. I am using Ajax Autocomplete extender to populate a textbox. usually there is a webservice method which populates data into the autocompletion list... but in my case, the data is coming via an instance method...
At the time of doing the autocomplete, the autocomplete calls the method, the data is getting lost in the page postback..My situation is such that I cannot use a static method to get data from database, since there is already a public instance method.I am using the technique of calling GetAutocompletionList without using a WebService method.
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
public static string[] GetAutoCompletionList(string prefixText, int count, string contextKey)
{
// want to use static viewstate here ..
I am trying to call a simple method in my code behind using Jquery with Ajax. But I get a 404 not found exception everytime. Unfortunately this is a web forms solution. So I dont have all the perks of MVC
It does get into the javascript method and gives the alert but won't go into my c# method. My previous experience of using this Jquery method is in an MVC website. Is it compatible with webforms sites?
Here is the code:

i want to make something like that
<cc1:AsyncFileUpload runat="server" id="upload"
onuploadedcomplete="Unnamed1_UploadedComplete">

i tried lots of script but it doesnt work.
I have a web user control. That I load dynamicaly inside a modalpopup window using dynamic populate extender. User control has a external javascript file linked to it.
