I was working on something with Page_Init. I palce a break point and noticed the event is called twice. What happen was:
1) Page_Init is called
2) Page rendered on browser
3) Page_Init is called again
How do I find out what is casuing it to fire twice? Page_load is also firing twice and this is happening on IE.
I'm debugging right now and it seems the Wizard.ActiveStepChanged method is called BEFORE the Page_Init method?!?
I've tried it several times now.
If thats the case: what is called BEFORE Wizard.ActiveStepChanged?
is there any way to find out the reason for session expiry?

View 2 RepliesIn one of my pages I use an usercontrol. The usercontrol has a textbox and a button on it. When someone adds text to the usercontrols textbox, I want to use the entered text in my page_init event. The problem is that in the page_init event, the textbox value is empty. How can I use the entered text in the page_init event?

However, when I reload the page, the cookie thisVisit becomes null.

My rest of the pages are being inherited from above basepage class. but the problem is that all the pages inherited from basepage class are not firing the event Page_Init...?
I have a gridview control with some linkbuttons in.
When the linkbutton is pressed, i want the ID value attached to it, to be usually in the Page_Init where i need to create some dynamic controls, based on this ID.
But since the linkbutton's click event, is fired AFTER the Page_Init, this is a little hard for me to do.
How would i go about doing this, if it is even possible?
The reason behind, is that the linkbutton refers to a calendar event. Once clicked, it will list the details, but it will also list any comments, users have submitted about it. The dynamic controls i need to create, are delete buttons for the comments, so an admin can remove offensive comments.
All done on a single aspx page, with updatepanels (visible toggles, and populating labels). I would like to avoid sending users to another page, with a horrible ?id=6 link.
i was debugging a test page when i noticed that its init and load event handlers are being called twice.
i found out by search that this may arise due to some html tags which im not using in my page,
also some line:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load,Me.Load
may cause this problem.
i use c# in the code behind aspx, if such line is the problem, in which file should i look for?
I am having a problem with web pages in a .Net site where the Page_Init is firing on each postback rather than the normal behavior (Page_Init fired initially, and only Page_Load fired on postbacks)
Several comments:
1. AutoEventWireup is set to false on all pages, with a "Handles Me.Init" set on Page_Init. All events are defined with the "Handles" verb as shown below
2. Each web page is subclassed to a parent class which provides strongly-typed access to the contents of session variables.
3. The Page_Load event for most of the pages performs a DataBind operation on a gridview control.
Partial Public Class SamplePage
Inherits PageManager (PageManager inherits from System.Web.UI.Page)
Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
...
End Sub
explain the diference between these Page_Init() and OnInit() events and when we should use which one?
View 2 RepliesI'm not sure if this belongs here since it doesn't seem to be a coding issue but...
I am having an issue with using httpwebrequest - the first time I run HttpWebRequest on a page there is a 5-10 second lag before it returns the data I am looking for. It doesn't matter from what source I am polling the lag is always there so it has nothing to do with the sites I am connecting to.
After I poll the first time as long as the page is reloaded within 1 and a half minutes afterwards the httpwebrequest response is lightning fast.
If I wait a minute and a half to 2 minutes without reloading the page the lag returns again.
I've tried everything related to tweaking the httpwebrequest settings and none have had any impact whatsoever.
If it helps I have older pages that use classic asp that behave the exact same way when returning data from external websites so it seems to me like a server issue.
What I am left with is...
I have a GridView and a TabControl. On click on the row of grid, I store the EmpId in a hiddenfield in javascript. Now in Page_Init, I am trying to load a usercontrol for a EmpId stored in hiddenfiled. But I am not able to access hiddenfield value in the Page_Init. It display empty. If I have to load the usercontrol during Page_Init, then I have to access the HiddenField value first and it is give problem.

View 2 Repliesi have a checklistbox that is databound during Page_Init in an
If (!Page.IsPostBack)
block. the user can then check off certain values, and click an asp.net button which posts back the form and renders a crystal report on the same page.
i need to be able to determine which items were checked in the control so that they can be used as parameters in the crystal report. rendering must be done during Page_Init.
the checklistbox object is on the page during design time; only the items are dynamic.
i tried using the Request.Form object during Page_Init to obtain the checkboxlist's items but either i didn't code it correctly or it can't be done that way...
can the checkboxlist items' values be obtained during Page_Init, and if so, how?

I know that in a web site project VWD will cram all the files into 1 specified folder which holds all the peices of your site together in a nice little container.
However, in a web based application (rather than web site) you have a similar folder but it contains a solution file; people often say this has more advantages, but from my early days of learning what would those advantages be?
I've noticed that ASP.NET automatically creates an App_Data folder for you whenever you make a new webforms application.
Since all of my data comes from a SQL Server 2005 database server, is there any reason to actually keep this folder?
I have some code I would like to execute very early in the lifecycle of a call to an ASMX function. For our ASPX pages, this code is in the Page_Init() function on a base class, from which all our ASPX pages inherit.
Is there an ASMX equivalent to the ASPX's Page_Init() function?
Better yet, is there an ASMX lifecycle diagram like the ASPX one? http://msdn.microsoft.com/en-us/library/ms178472.aspx
If there is an ASMX equivalent to Page_Init(), I assume I can implement code in a common base class, from which all my ASMX classes can inherit, correct?
Why the website developers use PNG format images in their webpages?
