Facebook Javascript SDK: Event Auth.sessionChange And Auto.logout Firing Only On Page Refresh?
Jul 30, 2010I have an implementation for my website to have facebook single sign on, using their javascript sdk.The javascript adds the cookie and I deal with it fine.The question is related to when an user logs out of facebook, I would expect the auth.sessionChange or auth.logout events to fire, but that only occurs when the page is refreshed.As my implementation is done server-side, this means that after the user logs out of facebook they can access one secure page one more time before being properly logged out.Is this the normal case or do these events usually fire up straight away and I'm maybe doing something incorrect in configuration of the facebook app?
View 1 RepliesHow To Prevent PostBack Event Handler From Firing
May 3, 2010I have a custom class (ServerSideValidator.vb) that validates user input on server side (it doesn't use any of the .NET built in validators, therefore Page.Validate() is not an option for me). I am calling the Validate() method on page.IsPostback event and the class performs without any problem
My issue is, when validation fails (returns false), I want to stop the postback event handler from firing, but load the page along with all the controls and user-input values in them. If I do, Response.End(), the page comes up blank. I can programmatically instruct the page to go to the previous page (original form before postback), but it loses all user-inputs.
I thought of creating a global boolean variable in the page code behind file and check the value before performing any postback method, but this approach takes away from my plan to provide all functionalities inside the class itself. The page object is being referenced to ServerSideValidator.
Seems like all the postback related properties/variables I come across inside Page class are 'Readonly' and I can't assign value(s) to control/prevent postback event from firing.
Web Forms :: Prevent The Firing Of Index Changed Event In A Dropdownlist When 'NO' Is Selected?
Mar 20, 2011I have a simple query based on the index changed event of a dropdownlist in ASP.NET. The scenario is i have a dropdown list bearing a collection of items (say ONE, TWO, THREE, FOUR, FIVE) with the default value selected as 'ONE'. Now, when the client changes the index (say the client selects 'TWO'), a confirmation box is prompted asking 'Are you sure want to change the index?' with the buttons YES & NO. Now, the problem is, if YES button is clicked then its working fine as the index is changed. But when NO button is clicked in the confirmation box, I do not want the index to be changed to 'TWO' and it should be holding the previously selected value which was 'ONE'. How can I do this? For which event should I write the code, as I cant think of writing the code for the IndexChanged event because here the index change has already occured and since there is no 'IndexChanging' event in ASP.NET, where shall i write the code

Web Forms :: Event Not Firing When Using Master Page

AsyncPostBack Firing On Child Textbox Trigger, But TextChanged Event Not Firing?
Jan 22, 2010I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:

Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.

AJAX :: All Controls Firing An Event On First Page Postback
Feb 8, 2010I have a web application that shows a page containing between 6 and 20 UpdatePanels, contained with Custom Web (.ascx) Controls.
You can see an example of such a page here: [URL]
The problem I'm getting is that when the user FIRST clicks any of the radio-buttons on any of the controls in the page, ALL the radio buttons that have an active selection ALSO fire an rb_CheckChanged event (see application log below). On subsequent radio-button clicks, only that RB fires the event (as expected).
This behaviour is having a dramatic impact on performance. The page loads quickly, and a "normal" RB click provides an AJAX update correctly within 1 second. The problematic first RB click, however, takes up to SIX seconds to process, which is unacceptable from a user experience standpoint.
Developed in VS.NET 2008, ASP.NET 3.5. Also I converted the "Web Site" solution to a "Web Application" (pre-compiled) and got the same performance (still too slow). Release builds run only marginally faster than debug builds.
Why would a single RB selection change cause all RB's that have a "selection" set on them to also fire? (The "selection" is determined through database settings every time the control is populated, which is called from within the parent page control's Page_Load function. This selection is determined also at first page load, since all the controls get populated then, so why would the clicking of an RB cause them all to fire an event, and only once? That's what I don't get...)

Web Forms :: Public Event RaiseEvent Not Firing In Content Page
Mar 3, 2010Here is the situation, I have a nested master page with set of global filters for reports. When they click the run button in the master I want the content page to process the filter and execute a general function called RunReport on the content page. Each report has its own content page with its own RunReport method. Everything I see online says to use public events with the RaiseEvent call. This was easy to code but it doesn't seem to be firing the event on the content page. How do I know, I have an error message section on the master page which I can send messages to from the content and it is displaying nothing. I also put a break point in the content page method and it never hit it. NOTE: MyPortal is a class that contains to variables call Master, which reference the main master page, and Validations which references the nested master page. The page does not throw any errors, it just refreshes like a normal button click. I have traced code to make sure it gets to the RaiseEvent call and when I tried to step into the code it skipped over the line. Here is some code for the nested master page:

Handling Browser Close Event And Page Refresh
Nov 16, 2010In our application we need to handle browser close event. When a user directly closes the browser, we should give him an alert message and stop him by directly closing the window based on some conditions. This we have handled through body onunload event. The problem is we are getting the alert message but after showing the alert message the window gets closed.
Is there any way to stop closing the window on click of browser close event?
And also when the page is refreshed, the last performed action is getting fired again.

Web Forms :: Menu In Top Level Master Page Not Firing MenuItemClick Event?
May 4, 2010I have a fairly complex web app which has two levels of master page. The top level provides a nav bar constructed from a Menu control across the top of the page. Second level master pages provide menus down the side. It all works well.
On both Menu controls, I need to handle the MenuItemClick event. This works fine on the Menu controls on the second-level master pages. However, the Menu on the top level master does not raise the event at all.
This web site makes extensive use of Ajax and the top-level master page contains the ScriptManager. Before I go to all the work of creating a much simpler test site, why the Menu control is not raising the MenuItemClick event?
Here is the markup for the Menu in the top-level master:
[Code]....
Here is the MenuItemClick event handler:
[Code]....
The logging call in the event handler never gets called. Equivalent code in the Menu on the second-level master does get called.
