How To Save And Retrieve Cookies Using Ajax Webservice Calls
Jan 26, 2010 I have web app which stores certain things on a page in a cookie when the page posts back in case the user doesn't finish what they're doing and come back later. But now I must do a javascript time-out and actively save the info to the cookie rather than wait for the user to postback. All my cookie code is on server side where I use Response and Request objects to read and write cookies and I want to leverage that. So I would like to just use ajax calls to a webservice. Is there a way for me to access Request and Response objects and read and write cookies to the browser via those objects during a webservice call? Or should I just go with javascript?
EDIT: Sorry i wanted to specify that I would like to use jquery-ajax.
AJAX :: Postback After Calling A Webservice From JavaScript?
Mar 23, 2011I have a page that calls a webservice from JavaScript using the approach described in this article: [URL]
This is working fine. The problem is when the page causes a postback before the end of the execution of the webservice's method. When that happens, the succeeded callback method never gets called. Does anyone know if there's a workaround to this?

View 1 RepliesAJAX :: Broadcast New Data Using Webservice?
Jun 8, 2010I am working on an application just like any fast food restaurant uses for example McDonalds.
Basically, application consists of three parts.
1) Web Application # 1 to take orders (Used by the clerk(s))
2) Web Application # 2 to process orders (used by the chef back in the kitchen)
3) WebService returns new orders (with PENDING status) to Web Application # 2.
Write now, Application # 1 adds new orders to the database. Application # 2 calls the WebService to get new ordes by REFRESSHING the page again and again. Refreshing the page over and over again is the problem.
I want the WebService to automatically send new data (oredrs with PENDING status) to Web Application # 2 whenever Application #1 add new order.
Application # 1 can call WebService (sending true flag) to let it konw that something has been added so the WebService can broadcast new date to Application # 2
Here is the flow which I am trying to achieve
Application # 1 (Takes new Order)
Application # 1 then call WebService (sending true)
WebService (if true is received), send new data to WebApplication # 2, cause postback on Applicatin # 2 automatically
For Example just imagine when you walk in McDonalds
Clerk takes your order -> New order is automatically send to the Kitchen (to process order)
Here is the breakdown
Application # 1 = Clerk taking order
WebService = Mechanism which is sending new order to Kitchen
Application # 2 = Monitor in the Kitchen receiving orders.
AJAX :: Webservice Returns Wrong Data?
Jun 25, 2010So I have a WebMethod that I call using jQuery. The method is supposed to return a unique URL to a image file created dynamicly.
The WebMethod is called in a for loop so anywhere from 1 to 50 calls gets fired async.
The problem is that the webservice seems to be using the same instance of the object, so that it returns the same value to a couple of the requests.
[Code]....
Shouldn't the WebMethod create a new instance of the class for each call, so that all values are stored individually in memory?

View 3 RepliesAJAX :: Fastest Way To Retreive Data From Database From Webservice?
Jan 25, 2010I'm using Webservice which will return the data from the database through datatable and I'll convert the datatable into byte array. In front end, I'll reconvert the bytearray to datatable and used ajaxloader to display it in the form.. It is dynamic loading. So, for each click, it is taking 10 seconds to retreive the data regardless of the size of the data. So, I used static datatable and I've loaded all data in that datatable in page load event. But, no reaction. It is taking only same time. Even, there is no data to retreive, the ajax loader is going on loading for 10 seconds. Problem is with Ajax or my webservice?? Plz, tell me some other idea??!!

AJAX :: Data From WebService Is Not Retained In Page History
Jan 19, 2011I am using a web service to pass back search results. To do this I am using ToolkitScriptManager with a ServiceReference to my web service and calling the web service up with javascript. The javascript call looks something like this:
WebService.GetResults("search term", OnSuccessGetData, OnFail);
If the request is successful the "OnSuccessGetData" function is fired and the results are inserted into a DIV tag. Because the resulting search results can be large I wrote the service to only pass back the first 20 results on the first trip. After that I make calls again to the service to return the next 5 results and continue to do this until all the results are loaded. This all works wonderful. You can see it in action at www.lsbio.com and use the search term "human mouse". My problem is that when the user clicks on a product and then hits the 'Back' button the search results have to be fetched again from the webservice.
Is there a way to keep the search results in the DIV tag to remain as part of the page so when the user navigates away from the search page and uses the 'Back' button to navigate back the search results are still there without having to hit the webservice again?
If I didn't make myself clear enough on what I am trying to do, go ahead and test the site www.lsbio.com, use the search terms human mouse, click on a product and then hit the back button.
Custom Server Controls :: CompositeControl Does Not Retrieve FormView Data On PostBack ("Save")
Feb 10, 2010Background:I'm building a custom control as a base class that derives from CompositeControl. It consists of a FormView, a ObjectDataSource and a CRUD-Button Series (Create, Read, Update, Delete - Buttons). I'm loading the different FormView templates within the deriving classes dynamically from file with Page.LoadTemplate().
Class structure:
TabControlBase:CompositeControl
Employer:TabControlBase
Applicant:TabControlBase
Each deriving class knows the specific template-paths for loading FormViews templates.
The ObjectDataSource is connected with a DAL using a Select and an Update Method. The Select-Method works fine: When loading the CompositeControl the data of the DAL are shown in the Labels of the embedded FormView (ReadOnly-Template). When I'm switching to Edit Mode the data also are displayed in the TextBoxes (Edit-Template).
The problem occurs when I'm trying to update data using the "Save" - Button: The connected DAL-Method is calling properly, but the parameters all are NULL.Tree structure of this custom control:
Panel -
--- FormView
EditTemplate (ascx): Name, Name1, Segment
--- ObjectDataSource
--- CRUD-Button Stack: New, Edit, Delete, Save, Cancel, Copy, Print
All controls will be added dynamically in the base class "TabControlBase" within the overridden CreateChildControls - method. The CreateChildControls method is called by the deriving classes e.g. Employer after setting specific properties e.g. templates,
object data source methods etc.The control is placed in a simple abc.aspx-Page. What I detected so far on PostBack
- When I'm looking at the ViewState Collection within the OnLoad-method of the abc.aspx the ViewState-Collection is Null (Count = 0)
- It seems that the control tree is empty. I'm not able to find any control using a proper working recursive FindControlMethod
- Only the Page.Request Collection shows the expected controls
Conclusion for now:It seems that the CompositeControl "forgets" the values of the FormView TextBoxes on PostBack. It seems it has to do with ViewState Management.

Web Forms :: Postback With RadWindow / On Clicking SAVE Or CLOSE It Throws A Dialog Box In IE And Firefox
Nov 18, 2010OK, here's my scenario. I inherited a website and I'm dealing with a quirk. I have a page that has a repeater with auto postback controls in it. And also a hyperlink or a button to open a RadWindow to add a new item or edit an existing one, the repeater probably could have been a Gridview, but forget that for now.
If you use the button to add a new entry or the hyperlink to edit, it works fine and closes and refreshs the page. BUT, after you click ANY of the auto postback check boxes and THEN try and use the new button or edit hyperlinks the RadWindow works, but on clicking SAVE or CLOSE it throws a dialog box in IE and Firefox letting the user know that:
"To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier."
IE's message is similar. Clicking RESEND works fine and everything is ok, but its a bit distracting to the user. The RadWindow open a page that has THIS javascript in it:
function RefreshParentPage() {
AJAX :: Check Whether Data Has Changed Without Postback?
Aug 14, 2010I'm not sure whether or not this is the correct forum...I have been asked to develop a webpage with a very simple table. 10 columns, 10 rows. Each cell will have a dropdownlist. Several people will have this page up at any given time and they will all make changes as needed. I am planning on using a SQL Server
2008 database to keep track of the entries.I need the page to verify the data it contains against the data in the database every 5 seconds or so. If they are different, either the page can refresh or (if possible) the dropdownlist can just change to the correct value.
