Initialize Session In Masterpage: 'subpage'?
Apr 4, 2011
I'm having a hard time with the page cycles when using masterpages and contentpages. My masterpage has two linkbuttons that are used to select a language (using resources). When these buttons are clicked I create Session["language"]. The goal I have is to 'translate' my masterpage after the buttons are clicked AND to translate the content page.I've been trying all kinds of different methods (Page_Load etc) based on this url: http://msdn.microsoft.com/en-us/library/dct97kc3.aspx but it never works like it should. Usually the content page only gets translated after two clicks. I can't figure out the cycle problem between the masterpage and the content page combined with the click-events.

I have one ASP.Net web page dynamically loading any one of about twenty User Controls at a given time. Since each user control is somewhat different, I've implemented the following extension to me pass a variable number of parameters to custom user control constructors: [URL]It, by the way, works very well! However, I've now come across the fact that both the web page and the user controls will need to share a few Data Tables. In other words, both the web page and the user control will need to access and manipulate data in these data tables.
To implement this fact I've used the Session object to store each data table. Each of these data tables starts out empty and then starts growing as the user enters more data into the user controls. The initialization of the data tables has to be done in the web page for a series of technical reasons that I won't get into here but rest assured that it does have to occur there.
But I found that in order to ENSURE that the initialization was taking place, it was simplest to just pass a reference to each data table as an extra parameter in the LoadUserControl call. This does work but it seems like overkill to me because on the user control constructor side, nothing is actually done with the data tables at the time of instantiation of the user control.
This made me go back to basics, thinking, "Why include a parameter if you're not actually going to use it?" But yet, it does seem to be the most straightforward way to ensure the data table is initialized and stored in the Session object.

I have a web site coded with VB + MS Access database (VS2010). I'm using one MasterPage to manage both public and users area. I'm facing loss of session variables when a user is logged in. I can't figure out what is wrong and I need your help, tips and tricks.
When a user is authenticated (thru the Login.aspx), I create a SessionID, store his credential in session and load user's page by Response.Redirect(~/users.aspx). Here is what I did:Code:
Dim MyLink As String = Session.SessionID & "other variables"
Session("MyLink") = MyLink
FormsAuthentication.RedirectFromLoginPage(TextBoxEmail.Text, False)
Response.Redirect(~/users.aspx)
My logic is this: when the web site is launched, MasterPage + Default.aspx load. So Session("MyLink") is empty. If the user's credentials are correct, I create the session so that it can be available for MasterPage.
In the code behind of the MasterPage, I try to check (everytime a link is clicked/page requested) whether the user session (SessionID, credential in session) is available. If so, the user is still logged and get access to all the menu. If no session is available, it means the user is logged out or not logged in yet and few menu are shown. Here is the code
Dim MyLink As String = Session("MyLink")
If MyLink Is Nothing Then
'Only show MenuPublic
[code]....
My default menu is:MenuPublic1, MenuPublic2, MenuPublic3
When a user is logged in, I add to the MenuPublic some reserved Users' menu like below.
MenuPublic1, MenuPublic2, MenuPublic3, Menu_Users1, Menu_Users2, Menu_Users3
In local, everything works perfectly fine. Now after hosting my website, from time to time the MasterPage loss the Session variables. When it happens, the page still shows that the user is logged in by displaying Logout and Welcome Username beside it.

I am working on some refactoring work from cold fusion to .Net and I have a login page which redirects to a mainpage --> aaa.aspx. It displays the current news from the database and then I have some links coming from the masterpage which are embedded inthe same page as well. This masterpage has links to pages which are in both .Net and CF.When the aaa.aspx was initially in Coldfusion, it would redirect to all these links in the masterpage without any issues, but from the time I re-wrote the aaa.cfm to aaa.aspx, the links in the master page that are embedded in the aaa.aspx would not work,i.e they would redirect back to the Login page. My session looks like it is persisting to the aaa.aspx page, but not to the master page elements.At this point, I am not sure as to what is causing this issue.

I have a web site using master page and login page. I use the MasterPage to check the availability of a session. I'm coding with VB + MS Access database.I believe something is wrong with my master page and I can't figure it out. In the code behind of the MasterPage, I try to check the user session is available.

Please note that my Login.aspx page is also base on the same MasterPage. On the Login.aspx.vb, if the user credential are correct, I did this:

So my logic is this: when the web site is launched MasterPage + Default.aspx load. So Sesson("MyLink") is empty. If the user's credential are correct, I create the session so the it can be available for MasterPage.My default menu isMenuPublic1, MenuPublic2, MenuPublic3When a user logged in, I add to the MenuPublic some reserved menu like below.MenuPublic1, MenuPublic2, MenuPublic3, Menu_Users1, Menu_Users2, Menu_Users3I'm testing my application on two different web hosting server: aspspider.com and somee.com. In the local, everything works perfectly fine.My problem is that on aspspider.com if a user logged in and then click on any MenuPublic, the application does not let him show information from Menu_Users. It's wrongly sending him to the login.aspx but still show his profil on the masterpage and the "welcome username" with beside the Logout link. It seems like the user is still connected but cannot have access to users pages.On the other server (somee.com), even if the user logged in successfully, I still have "welcome guess" with beside the Login link. I also have the user's profil information with all the links. If a user click on any MenuPublic, he can still see all the Menu_Users. But if he clicks on any Menu_Users, the application redirect him to the login.aspx; but still displaying all the information as if he is logged.The package deployed on both server is the same; except the connection string.FYI, I have Global.asa in the package but I don't use it. The web.config has plenty of stuff that came when I first start the project. The only thing I added is the connection string.

Situation:In Web.Config we have CustomErrors turned on with redirectMode="ResponseRewrite".In Page_Load of our MasterPage we access the Session property of the Page.
Problem:When an Error occurs on any page the user gets redirected (via Rewrite) to our Error.aspx Page. There in the Page_Load of the MasterPage we access the Session and get an HttpException telling us to enable SessionState. But we have the SessionState enabled, definitly.
Question:How can we access the session after a UrlRewrite in the Page_Load Event of our MasterPage?

In my application, session value automatically set into null.In certain workflow only it will set as null (Normally It's able to access value). Example, at the time of login, I will set session values. While, user deleting some entries from drop down list of specifc page,client script will show message like selected entry deleted. After that, flow point will move to master page. There I have to access session variables. It's getting null value. I tried to debug with Quick watch, at the pageload of master page only value set into null (automatically).

I have a MasterPage (MasterPage.master) with 2 child MasterPages (specialMaster.master and standardMaster.master). From the MasterPage.master I need to get at some of the controls in one of the children, specialMaster.master, say for example to hide certain
content if a session variable is not null.

I want to create my own naming convention for page events rather than AutoEventWireUp but I couldn't find Component Initialize methods any where ? Should I override it ? But in which class it is defined ?
Edit :
For example : I don't want to use Page_Load but LoadThisPage naming. So It should be like
Load += new LoadThisPage(sender,e);
I was expecting a InitializeComponent method where I can initialize page,controls etc. events handlers...But it turned out to be Constructor function :
So what confused me is I thought there should have been a method like InitializeComponent which does things for me already created by Designer itself so I thought I could define my own event handler names within this method by overriding it in the say Default.aspx.cs .

I have - for instance - an asp:FormView which supports Read, Insert, Update, Delete and is bound to a DataSource:
[code]....
If I am in Read-Mode or Edit-Mode the control is initialized with the property MyText of the current object which is bound to the FormView.
But when I go to Insert-Mode I do not have a "current object" (FormView1.DataItem is indeed null) and the controls are empty.
If I want to have my TextBox control initialized with a specific value how can I do that? In which event can I hook in to set default values to the controls in the InsertItemTemplate?
Especially I have in mind using an ObjectDataSource. I was expecting that the InsertItemTemplate is initialized with a business object which underlies my ObjectDataSource and which is created by the ASP.NET framework simply by using its default constructor when the InsertItemTemplate gets activated. In the default constructor I would init the class members to the default values I'd like to have in my controls of the InsertItemTemplate. But unfortunately that's not the case: No "default" object is created and bound to the FormView. So it seems I have to initialize all controls separately or to create the default object manually and bind it to the InsertItemTemplate of the FormView. But how and where can I do that?

I was looking for a custom membership/role provider and came across The Altairis Web Security Toolkit Looked at the source and this is just perfect for what I had in mind. So I implemented it in my project, created a database and tables and configured it in my web.config. Everything compiles fine, but seems I'm being stupid in how to actually use it. (Looking at the source code here might be useful in helping me out) Just to see it work, I'm making a call like this:
Code:
private readonly KrokSqlMembershipProvider_membershipService;
_membershipService = new KrokSqlMembershipProvider();
MembershipCreateStatus status;
_membershipService.CreateUser("krok", "password", "[URL], "", "", true, null, out status);
However when I debug the code, I realize that in the MembershipProvider class the configuration settings to be loaded from the web.config are empty, so it fail when trying to connect to my database (empty connection string). I notice the settings are retrieved in the Initialize method, but I'm not sure if I'm suppose to call that, and if so, how. (The sample application that comes with the source code have no code in it. It's asp.net, while I'm using asp.net mvc)

I have a site that uses ActiveRecord. I'm getting an exception that says "An ActiveRecord class () was used but the framework seems not properly initialized. Did you forget about ActiveRecordStarter.Initialize() ?" This is a web application, and the Initialize() method is called by the Application_Start event handler.
I created a new page that also calls the initialize() method. If I visit that page once, then the rest of the site works. If I visit it a second time, I get an exception stating that the Initialize() method can only be called once.
I've tried modifying the web.config and resetting the application pool to force Application_Start to run.
This only happens in production; dev, my stage, and client stage are fine. Production is the only load-balanced environment--I'm not sure if that comes into play.
Edit: We have another site deployed in the same environment which successfully uses ActiveRecord with the same initialization code. One difference is that the site that is working has only the ActiveRecord code in Application_Start; the site that doesn't also sets up some URL routing in Application_Start.

I am using a Telerik combobox and using jquery to make a clone of it.
the control is being rendered correctly, however the dropdown is not working I believe due to the fact the javascript has not been initialized on the control.
Is there a way to do this or a better way to make a duplicate of the control?
I may have to resort to making an ajax request but would ideally like to keep it all clientside.
