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 RepliesEvent Of Master Page Not Firing
Jul 23, 2010I put a break point at the protected void Page_Load(object sender, EventArgs e) method of my master page, but when i start the site it does not hit that break point.
Why is the event not firing? I would like to use this event along with others such as the Init event in order to check to see if the session has expired everytime a page loads...

Web Forms :: Event Not Firing When Using Master Page
Aug 3, 2012I'm using SelectedIndexChanged on a gridview row to trigger an event which is working fine in a normal webform. But, when I included "master page", it's not triggering the same event.
everything is same except, I added MasterPageFile location & removed FORM tag.
ASP code
<%@ page title="" language="C" masterpagefile="~/site.master codebehind="test.aspx.cs" inherits="Main.test" enableEventValidation="false"
autoeventwireup="true"%>
<asp:content ID="content1" contentplaceholderid="headcontent" runat="server">

Web Forms :: Master Page Event Not Firing On Remote Web Server
May 18, 2010I have a master page with a login box on it. Inside the login box is a button -
[Code]....
NOW ... On my local dev machine this code works fine. The control fires the event and everything is how it should be. When I run this site on a remote web server (tried two of them - both IIS7 running on 2008 R2) the event is never called. I added some logging to see what is happening and the PostBack event on the Master Page does not happen when the button is clicked - the page is just reloaded.
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.
Web Forms :: Master Page Load Event Firing Multiple Times
Jan 27, 2010 am using a master page, with children pages.
I am using forms authentication, and a session object to hold user information once the user is authenticated.
I am able to login and log out. I am able to log in and use the "remember me" functionality of the forms authentication.
When attempting to test the "remember me" functionality, the master page load event contains code to check the forms authentication & remember me, and retrieve user info from the database to automatically log the user in. This fires correctly, and the screens all load with the user successfuly logged in, and the users info is successfully stored in a session object.
Without touching anything on the screen, a moment passes and then the master page load event spontaneously fires again, Page.User.Identity.Name still contains the user name, however the session variable is now null, and throws an error.If I tell it to run past this error, it does, and the application continues to function normally, withthe session variables set correctly.
Its almost as if that second firing is ina different session, or something.
I have no problem posting code, but I have a profile class holding / handling the session communication, etc so it is a bit cumbersome.

Web Forms :: DropDownList Not Redirecting To Page Using OnSelectedIndexChanged Event

AJAX :: UpdatePanel OnSelectedIndexChanged Not Firing?
Sep 15, 2010I have an UpdatePanel with a dropdownlist (countries) and a multi-select listbox (locations). If the user selects a country, the locations for the country get populated. By default, all locations must be selected.
Works absolutely fine, except that if you choose a country, then change the country back to the original value ("All Countries") - the OnSelectedIndexChanged doesn't fire. Page PostBack occurs, tho.
AutoPostback is true, everything else works fine, just can't get the darned event to fire on when the original value is Selected. The result is that the drop-down list gets populated with the default list of locations (for All Countries), but they aren't selected...only the subset from the previously selected country are selected?
Using The Facebook C# SDK For Fan Page Custom IFrame Tabs
Mar 11, 2011I'm trying to create a simple iFrame custom tab on my fan page. I'm using the Facebook C# SDK and I need to read the signed_request value that Facebook passes to my iFrame page.
I can print the signed_request encoded value so I know its showing up, but when I try to decode it with the Facebook C# SDK I'm getting an error. I'm using .NET 4.0 and dynamics.
Here's my code:
signedRequestString contains the Request value with the signed_param passed from Facebook.
var result = FacebookSignedRequest.Parse(FacebookContext.Current.AppSecret, signedRequestString);
dynamic signedRequestJson = result.Data;
dynamic page = signedRequestJson.page;
And the error I receive:
Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: Cannot perform runtime binding on a null reference at CallSite.Target(Closure , CallSite , Object ) at System.Dynamic.UpdateDelegates.UpdateAndExecute1[T0,TRet](CallSite site, T0 arg0) at DecodeSignedRequest(String signedRequestString)
why I would be getting a null?
Web Forms :: Dropdown List - Default Value And OnSelectedIndexChanged Doesn't Fire
Jun 7, 2010I have a dropdown list that is populated by a dataset (Data being extracted from DB). Based on the selection made by the user I call OnSelectedIndexChanged, and populated the form with the relevent info. The problem I am having is the first item in the list is selected by default, so if the user selects this option OnSelectedIndexChanged does not fire. To work around this I add a default item to the dropdown list after populating it with the dataset as shown here;
jobStandardActList.Items.Insert(0,
jobStandardActList.SelectedIndex = 0;
jobStandardActList.SelectedValue =
"----Select an Item----");"";
This works fine, however if the user selects an item from the list, and then proceeds to selects the default item "----Select Item----" i receive an error. sys.webforms.pagerequestmanagersevererrorexception: an unknown error occured while processing the request on the server. The status code returned from the server was: 500

View 1 RepliesPage With Base Class With Dynamic Master Page Not Firing Events
May 3, 2010I am feeling that I have terribly wrong somewhere. I was working on a small asp.net app. I have some dynamic themes in the heme folder and have implemented a page base class to load the master page on the fly. The master is having the ContentPlaceHolder like: <asp:ContentPlaceHolder ID="cphBody" runat="server" />
Now I am adding pages that are derived from my base class and added the form elements. I know, Visual Studio has problem showing the page in the design mode. I have a dropdown box and wish to add the event of onselectedindexchange. But it is not working. the page is like this:
<%@ Page Language="C#" AutoEventWireup="true" Inherits="trigon.web.Pages.MIS.JobStatus" Title="Job Status" AspCompat="true" CodeBehind="JobStatus.aspx.cs" %>
<asp:Content ID="Content1" ContentPlaceHolderID="cphBody" runat="Server">
<div id="divError" runat="server" />
<asp:DropDownList runat="server" id="jobType" onselectedindexchange="On_jobTypeSelection_Change"></asp:DropDownList>
</asp:Content>
I have also tried adding the event on the code behind like:
protected void Page_Load(object sender, EventArgs e)
{
jobType.SelectedIndexChanged += new System.EventHandler(this.On_jobTypeSelection_Change);
if (!IsPostBack)
{
JobStatus_DA da = new JobStatus_DA();
jobType.DataSource = da.getJobTypes();
jobType.DataBind();
}
}
protected void On_jobTypeSelection_Change(Object sender, EventArgs e)
{
//do something here
}

C# - Get The Previous Item On DropDownList Before OnSelectedIndexChanged Fires The Event
Jan 26, 2011How would I get the previous item on DropDownList before OnSelectedIndexChanged fires the event?
I had a DropDownList that has names as its items ("John", "Mark"). By default the SelectedIndex is "John". Upon changing its index and selecting "Mark" the event OnSelectedIndexChanged will be triggered. When I use ddlName.SelectedIndex it will return only the index for "Mark" which I want to get is the index of "John".
ListBox Dosn't Fire OnSelectedIndexChanged Event When SelectedIndex Is Changed?
Aug 24, 2010I have an asp.net page with a list box on it. Multiple event handlers subscribe to its OnSelectedIndexChanged event.
When I change the SelectedIndex programmatically none of the events get fired.
Now a hack for this is to call each event handler, but this has already caused bugs since people didn't know they had to do this when adding a new event handler.
I can do this in a Winforms app and even when SelectedIndex is changed in code the events fire.

View 2 RepliesMaster Page Menu Button Events Not Firing On Some Pages Only?
Aug 5, 2014I have a master page with a menu on it. I have found now two pages out of dozens where for some reason the master page events aren't firing. I've put a break point in there and it never hits it. Is there something that could cause a disconnect between the page and the master page events? Really weird it happens in Chrome and IE but they fire correctly in Safari.
