How To Make A Concurrent AJAX WCF Web Service Request During An Async Postback

May 22, 2010

I want to provide status updates during a long-running task on an ASP.NET WebForms page with AJAX.Is there a way to get the ScriptManager to execute and process a script for a web service request concurrently with an async postback? I have a script on the page that makes a web service request. It runs on page load and periodically using setInterval(). It's running correctly before the async postback is initiated, but it stops running during the async postback, and doesn't run again until after the async postback completes.

Jquery .ajax Async Postback On C# UserControl

Mar 29, 2010

I'm working on adding a todo list to a project system and would like to have the todo creation trigger a async postback to update the database. I'd really like to host this in a usercontrol so I can drop the todo list onto a project page, task page or stand alone todo list page.

Here's what I have.User Control "TodoList.ascx" which lives in the Controls directory.

The script that sits at the top of the UserControl. You can see where I started building jsonText to postback but when that didn't work I just tried posting back an empty data variable and removed the 'string[] items' variable from the AddTodo2 method.

<script type="text/javascript">
$(document).ready(function() {
// Add the page method call as an onclick handler for the div.
[code]...

I can have a control that can be used to display multiple todo lists and create a brand new todo list as well.When I click on the #divAddButton I can watch it build the postback in firebug but once it completes it runs the error portion by alerting 'error'. I can't see why.

I'd really rather have the response method live inside the user control as well. Since I'll be dropping it on several pages to keep from having to go put a method on each individual page.

AJAX :: Margin On Div Removed After Async Postback With UpdatePanel

Sep 15, 2010

I have a series of div's inside an update panel, these divs have a margin-bottom defined in css. In IE8, when I do a async postback these margins are all removed. All the other styles are fine. If I turn on compatibility mode this does not happen. In Google Chrome the margins are maintained correctly after the async postbacks.

AJAX :: Losing Javascript Events On Async Postback?

Apr 27, 2010

I am creating a ASP.Net server control to manage locations. The control is a composite control containing several text-boxes, labels, and a link button. I use the AJAX Control Toolkit to provide a modal popup which contains a Bing map. All the Javascript is in its own file and used as an embedded web resource.

The link button is what opens the modal popup. It also needs to call a Javascript function that initializes the Bing map (onclick = "GetMap();"). There are instances when this server control is placed within an Update Panel (and there is no way to avoid this). When in an Update Panel the link button loses its onclick event. I understand that this is because during an async postback the portion of the DOM that defines the content of the Update Panel is thrown out and reinitialized, resulting in the event breaking. When the control is not in an Update Panel everything works as intended.

I have tried registering events on Page.Load and Page.Init, like so:

[Code]....

I have also tried flat out writing the function call to the page:

[Code]....

I have put breakpoints on the lines inside each delegate and they do not get hit. I am not aware of any special way to register events of a composite control's child control or the Page.Load/Page.Init events when being done inside a server control. Is there some special way to register these events? (Note: Both those code blocks above are in my CreateChildControls() method)

Below is the GetMap() Javascript function. As you can see it is pretty straight forward.

AJAX :: HoverMenuExtender Stops Working After Async Postback In Updatepanel?

Feb 23, 2010

I've got a problem that after i refresh an update panel all the HoverMenu's stop displaying, it still calls the WebMethod which returns valid html and the panel is displayed, but it content of the panel isn't displayed on the browser.

I've created a single page to demo this problem:

aspx

vb.net

The demo shows the hovermenu working until you click the update button then it stops showing the content, although it is still calling the WebMethod onhover.

AJAX :: Determine If User Control Is Contained By The Update Panel That Triggered Async Postback?

Sep 16, 2010

Does anyone know a simple way to determine if a user control is contained in an update panel that was triggered for async postback?

At the moment, the only pseudo logic for this I can think of is?

'Loop through the update panel controls on the page and find the one that is involved in the postback (isInPartialRendering)

'Try to find the user control as a child of the update panel

AJAX :: Simple Async "Server Push" Using AJAX And Web Service?

Jan 21, 2011

this has probably been discussed before but perhaps not enough as I haven't been able to find any literature on this method (parts are documented, but not as a whole I guess)Anyways, you start with a web service, and you call that web service client side with ASP.NET AJAX javascript. Once you get a reply, you can call a artial postback using __doPostback(a, b) and "a" is the control id of an updatepanel in your page and "b" can be an indicator for which web service you are using or your resulting data or both. Lastly you add a check for "a" and "b" like this:

[Code]....

Now you can execute any code behind function when you receive a response, and because it's async anything short of leaving the page and it will still postback when you get a response.For example, I have a site which display data from a database in a gridview and uses a client side web service to get the time last updated for a database, call the web service client side every second, then, when an update is detected, call a partial postback, alert the user, and update the gridview.Though this really is a hack, so I'm not sure if there any problems with this approach, if there's a simpler and better way to go about it (I'm all ears).

Switch From Async PostBack To Full PostBack In An Update Panel?

Aug 20, 2010

Is something like this possible?

Dim iCounter as Integer
Dim iQuantity as Integer = 10
Protected Sub btnFoo_Click Handles btnFoo Yadda
For i as Integer = iCounter to iQuantity - 1
//do something with AsyncPostBackTrigger until iCounter = iQuantity - 1
//then trigger a full postback
Next
End Sub

I am new to the concept and feel like there must be something really easy that I am missing.

AJAX :: Make A SOAP API Request - PayPal Using 3.5?

Jan 20, 2010

This is so frustrating to me. I'm doing this via standard .NET 2.0+ web services (not WCF). My application is in .NET 3.5 but I'm just adding a service reference. I've not done any SOAP WSDL sending before. I've used NVP which to me seems much more error prone and burdensome because you have to create all the wrappers yourself and if any of that third party API changes, it breaks your code. I have not a clue how to make a call using the latest PayPal WSDL. I added the service reference and I see proxy classes such as [className]Request and [className]Response but how do you actually make the CALL and send the request over the wire?

I see people have used the outdated (.NET 1.1) PayPal SDK. We do not want to use an SDK just to send a request. Isn't it much easier nowdays in .NET when using any SOAP API to invoke the request? People for example using PayPal are relying on a caller class from that SDK but again it's way, way outdated. So onto today, .NET 2.0+, I thought that you don't need all that plumbing anymore?

How would I do this? I see no good documentation on the net period on .NET 2.0 or 3.5 web services especially SOAP and it's frustrating. Sure add the service reference, use the WSDL and proxy generated class wrappers but outside this HOW to make a request is impossible to find. I'm seeing legacy ways of doing this in .NET and then I hear this is all done under the covers for you in .NET..I guess that must be .NET 2.0+ ?? Is it as simple as just making the proxy class method calls and .NET under the covers takes care of the plumbing to actually send the request over Http unlike .NET 1.1 where you had to do all the plumbing yourself?

MVC's AsyncController Be Used To Service Large Number Of Concurrent Hanging Requests (long Poll)??

Feb 13, 2011

Frameworks like Node.js, Tornado, and Twisted let developers create server-push applications that supports large number of concurrent hanging requests (10k+). From what I understand, they all achieve this by not creating threads to service each hanging request.

Can AsyncController be used to service large number of inactive concurrent requests?If so, are there any reasonably large ASP.NET MVC websites using this approach to create long-poll applications?

AJAX :: Unable To Make Wcf JSON Ajax Service Work Through Http Like Asmx?

Jun 22, 2010

I am new to WCF, I was using web service asmx before. I have trouble on making my wcf JSON ajax service work through http like asmx.Could you help me see what wrong in my code?My WCF services are defined in my website application folder. My aim is to call this service in my aspx page java-script code and return complex object back as JSON to my javascript. I have no problem on doing this through classic asmx web service.


When I try to test it through my browser by type this in the URL , URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc/GetAll. it return "Method not allowed."

But if I type just this URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc, it return this:

WCFCompanyService Service

You have created a service.To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax:

svcutil.exe URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc?wsdl

This will generate a configuration file and a code file that contains the client class. Add the two files to your client application and use the generated client class to call the Service. For example:

C#

class Test { static void Main() { HelloClient client = new HelloClient();

[Code]....

This is my Ajax-enabled WCF service code:

[Code]....

This is the web.config service model setting

MVC :: Client Scripts Not Running After Async Postback?

Feb 28, 2010

I have a MVC view, say,:

[Code]....

somepartialview calls other partial views, that also contains client javascript. This loads and works fine, the javascript-based effects (vertical ticker, horizontal ticker) work fine as well.

The problem is that somepartialview has several AJAX.ActionLink(s) like this:

Ajax.ActionLink("LinkText", "SetIcons", new { id = l.ID }, new AjaxOptions { UpdateTargetId = "ajaxdiv" })
Namely, an <a> element which upon click changes the content of <div id="ajaxdiv"> using a 'SetIcons' controller:

[Code]....

But this works only partially: the page gets refreshed with the new HTML content, but the scripts that worked before the async postback do not run anymore. How do I get them to work?

I think that I am looking for the MVC alternative of the WebForms' ScriptManager.RegisterStartupScript

OSDBDataContext db = new OSDBDataContext();

I have a web application that does some complicated data retrieval tasks and so I am trying to show a modal dialog box with a loading message when the tasks begins. I am using ASP.Net 3.5, the jQeury popup I am using is bPopup.

Firstly, I have a table where the rows can be clicked. Im am using a script from[URL] to do an async postback from the table row. Here is my function

[Code]....

so the $("#<%=lDiv.ClientID %>").openPopup(); opens up my loading modal and then the server starts doing its thing. When the server finishes though how would I then close the dialog box?

I just need to call one line of code like $("#<%=lDiv.ClientID %>").closePopup();

Classic .NET : Make Multiple Async Calls, Return When All Complete?

Sep 14, 2010

I need to gather information (via GET) from several other websites (not under my control), do some processing (specific to each source) on the data returned, and then print all the info out to the user.

Right now I'm making the GET request to website A, waiting for it to return, processing it, then calling website B, and so on... Obviously this is too damn slow. I'd like to make async requests to A, B, and C, then process each response as it comes back, and once I have all the responses, print it all out to the user.

I'm allowed to use classic asp or vb.net. I'm more familiar with classic asp but I'm willing to learn...

Forms Data Controls :: Async Postback Upon Click Of 'Update' Button In GridView?

Feb 9, 2010

I have a GridView within an UpdatePanel - <asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="true">

Without listing any Triggers, I get a full postback when I visit a particular row within the GridView and click the 'Edit' button for that row.

However, if I enter the following trigger...

<Triggers>
<asp:AsyncPostBackTrigger ControlID="GridView1" EventName="RowEditing" />
</Triggers>

...I get an async postback when I click the 'Edit' button for a particular GridView row. This is what I want. In fact, I also get an async postback if I then click the 'Cancel' button for that GridView row which appears after having clicked the 'Edit' button.

However, if I instead click the 'Update' button that appears after having clicked the 'Edit' button, I get a full postback. I have tried almost every GridView EventName

I can find to add to the <Triggers></Triggers> section to get a click of the 'Update' button to result in an async postback, but with no luck.

What EventName should I use in the <Triggers></Triggers> section to get a GridView to do an async postback when clicking the 'Update' button for a particular row?

How To Make Calls To A WCF Service With Jquery Ajax From An SSL- Secured Page

Jun 6, 2010

I have a WCF service returning JSON to jQuery ajax calls and presenting the results on an ASPX page. When the page is NOT under SSL, the ajax calls work perfectly. When the page IS under SSL, the calls fail. I understand that this behavior must be due to the Same Origin Policy (SOP).

So, how do I setup my WCF service to accept calls from an SSL-secured page? Does the WCF service also need to be secured? If so, how do I do this?
