Does/Will Autofacs Integration Support PreInit Or Init Events
Mar 10, 2010
I see from around in the 1.4.4 source that Autofac's ASP.NET integration (via Autofac.Integration.Web) peforms injection of properties on the Page as part of the HttpContext.PreRequestHandlerExecute event handling, but that the page's child controls don't get their properties injected until Page.PreLoad.
What this means, though is that the injected properties of child controls are unavailable for use in the OnInit event handler.
For example, this works fine:
HelloWorld.aspx:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="HelloWorld.aspx.cs" Inherits="HelloWorld" %>
<html>
<body>
<asp:Label runat="server" id="lblMsg" OnInit="HandleInit"/>.........
But changing the HelloWorld Page to a UserControl (.acsx) and putting the UserControl in another page doesn't work because _msgProvider isn't injected early enough.
Is there a way to make Autofac inject properties of child controls earlier?

Just I started learning MVC pattern, of course i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there)
1 ) MVC does not support server side events, but supports client side events. If it supports client side events, I need html page with jQuery/Javascript (view), but most of the example I absorbed is to display the information(model) in view, I did not see any client side event handling happens in view.
2) Except ViewState and controlState, MVC supports Sessions, Application State management, Cache management.
3) When request goes to MVC engine, the routing module routes the request that is picked up by the controller. The controller in executes the appropriate action and returns the appropriate view.

How to get control in ASP.NET PreInit event? Pointers are null and FindControl method returns null.
I am using master and content pages. Markup of the content page looks like this:
<asp:Content ID="Content2" ContentPlaceHolderID="ContentBody" runat="server">
<asp:Table ID="Table1" runat="server" Width="100%">
.....
</asp:Table>
</asp:Content>
And code like this:
private void Page_PreInit(object sender, EventArgs e)
{
Control table = this.FindControl("Table1");
//table is null here
}
So table still is null after this.FindControl("Table1"). NamingContainer of the page is null too. What am I doing wrong?
UPDATE I have to use this event to create controls. As said in the ASP.NET Page Life Cycle Overview this event should be used for dynamic control creation. I need to create a list of links in my table. May be there is another way to do it?

I have a content page with a grid view control in it. In the page preinit event of this page, i am trying to add a column to the grid view. But the value of the grid view shows up as null. Is there something i am missing or how do we add properties to the grid view in the page pre init of the content page.

I'm referencing this article:[URL]Specifically, this line:
"The Init event for each child control occur before the corresponding event is raised for its container"
I've never noticed this behavior before, but can definitely see that this is correct. I don't understand WHY this is necessary though. Can someone shed some light on this?

During a recent interview the following question was asked.
- A Master page which contains
- An ASPX web form page which contains
- A Web User Control inside the page which contains
- A button to fire some code in a button_click event
The Init Event will fire (Inner Most to Outer Most)
aspx.page Begin Init
-> Inside user control Page_Init
-> Inside master page Page_Init
-> Inside lifecycle page Page_Init
aspx.page End Init
and Load Event will fire
aspx.page Begin Load
-> Inside lifecycle page Page_Load
-> Inside master page Page_Load
-> Inside user control Page_Load
aspx.page End Load
Why does ASP.NET framework support different execution order in Load() and Init().This was the question asked in interview.I have no idea about what the interviewer expecting from me.

In S#Arch based web application I need to read some data during the application initialization. From the first point, the best place - HttpApplication.Application_Start() or HttpApplication.Init()But, Application_Start isn't applicable as there is no WebSessionStorage yet. Init() seems isn't fit as well, as there is no NHibernateSession.

So I've got a databound grid view within a UpdatePanel.
the user can change the data within the gridview then click a save button to update the data within the database.
However in order to know which rows have been changed I have a textChanged event associated with each textbox, but the event isn't being fired.
Here's the ASP code:

I have been tasked with designing a scheduling system to fit into an existing application. At present I have a SQL Table - Tasks which have a StartDate and EndDate column.
I have a requirement to set the Task as a recurring task i.e. Replace server backup tapes every day, or, Order more stationary once a month.
I am lost on how to design this. I can't seem to find a proper example on the net. can someone point me in the right direction.

I am creating a dynamic <asp:Table> based on a user's selection from a DropDownList. The number of columns and rows in the table depends on the user's choice from the DropDown.
The final two columns in each row needs to contain an Edit and Delete button. I am able to create these buttons programmatically. However, I am unable to get the click event to fire.
After researching this, it appears to be the case that my dynamic Web controls need to be created in the page Init method.
However, I am unable to do this as I do not know how many table rows, columns and buttons to create, until after the user has made a selection from a DropdownList.
I would be be very grateful for some tips on the correct way to create and enable the events for my dynamic buttons, in this scenario.
Here is a brief outline of how the program currently works (this is just a brief outline I quickly sketched, small details may be wrong!):

I have a custom control with a UpdatePanel inside. Depending of user action or page programing I call Update method of my UpdatePanel to refresh html portion to user.
For example, I created a property called Title. If the Title change i call Update of my UpdatePanel.
[Code]....
But if the Title property is configured on aspx file, my UpdatePanel is always refreshed because my Title property is setted on Init stage of page life cycle.
I need to know if this property is setted on init stage or if ViewState is restored to avoid call Update, or any tips to avoid refresh my control everytime.

Web application initialization is as follows:
As we know when IIS receives the first request for a particular Asp.net application resource, IIS creates an instance of a HttpApplication (defined in global.asax codebehind).When this new instance is created it's initialization happens that also checks all configured HTTP modules.All modules are then instantiated and put in the application's Modules collection (of type HttpModuleCollection)modules are looped through and their Init() method is called (when they register for request events)
As far as I understand it the above scenario happens when a web application is started/initialized (hence application start event).What happens with modules?
Are they (re)instatiated on each request or reused from the Modules property on each consecutive request while the web application is alive? As I understand IIS and Asp.net they are reused through the whole life of a web application.
If they are reused, can we assume that their Init() method is actually a pseudo event handler for application start event? The thing is we can't attach to application level events within http modules. But if they are being reused we could use Init() as application start event and do whatever we'd put in global.asax instead.
Question,Can we assume that module's Init() method is called only on application start event? Could we use this assumption to i.e. register routes for applications whose global.asax codebehind we can't change? web.config is usually accessible and we can change it the way we want.Would this actually work?
Additional info,We can check HttpApplication code and check its InitModulesCommon() method. This one actually calls Init() of each registered HTTP module. What is more interesting is that this method is only used by InitIntegratedModules() and InitModules() methods. Which are both used only in HttpApplication.InitInternal() method. This is the basis of my assumptions, but I would like to know whether someone has abused IHttpModule.Init() for application start event.

im using a init function after partial postback again the init function is not calling.
<asp:ScriptManager runat="server" ID="MainSM" EnablePartialRendering="true">
<Scripts>
<asp:ScriptReference Path="~/JS/menu.js" />
</Scripts>
</asp:ScriptManager>
<script type="text/javascript">
menu.init("class");
</script>
this script works fine but after partial postback again this init function is not working. So i searched in google i found some articles regarding this [URL]
<script type="text/javascript">
function pageLoad() {
// Initialization code here, meant to run once.
</script>
this works fine when it was postback,but without postback this init function is not working

I have a page with 2 Controls, a ListBox and a DropDownList.
In the DropDownList you can select a PLACE.
In the ListBox you can see all DOCUMENTS for the selected PLACE.
If you select a DOCUMENT, the program does a redirect on the selected DOCUMENT.
So, there are an AutoPostBack and an Event (if you select another Item) on both Controls.
The problem is: If I select a PLACE, then I select a DOCUMENT (the pdf document is opened), and then I go back on the page and I want to select another PLACE, the program doesn't select another PLACE, but opens the old DOCUMENT, because there are 2 Events, one to change the PLACE and one to open the DOCUMENTS.
Can I give a priority at the Events?

I read this article first to try to solve this issue, but I am already loading the controls in the Init phase of the page, yet viewstate is not persisting. Any ideas as to why? (Of note is that this is for a custom module in DNN and I do have some AJAX update panels on the page, though this section is not within an update panel, for what it's worth.)
As an overview of what I've got:
1. LoadControl.ascx - based on reading query string parameters, determines whether to load the master or the detail .ascx.
2. Master.ascx
3. Detail.ascx
In my master control I dynamically load either a master or detail sub-control in the page_Init. The detail page has a treeview control and then uses a multi-view control to display the panel associated with the depth of the node selected on the tree. On the panel being displayed I have a cascading ddl within a detailsview control which initiates a postback to select the child ddl based on the parent ddl selection. However, when the page refreshes after the postback, both ddls have resorted to their default selection.
What is interesting however, and I just realized this as I am typing, is that the Treeview is populated when the page comes back from the postback, so that is only possible if viewstate is being persisted right? (See the page_load code and you'll see that Call PopulateRootLevel(intTreeUserID) which populates the treeview, is not called on postbacks....hmmm.
Any ideas as to why the treeview maintains viewstate but not my ddls???? But though the tree is populated, I do have to explicitly select the node again and set the panel that the detailsview control is on to visible again too....
Here is the dynamically loaded control code:

And in the Detail.ascx page load I've got:
