I am using a baspage class for my session checking by the following code
[Code]....
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 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 have a gridview that includes dynamically created dropdownlist. When changing the dropdown values and doing a mass update on the grid (btnUpdate.click), I have to create the controls in the page init so they will be available to the viewstate. However, I have several other buttons that also cause a postback and I don't want to create the controls in the page init, but rather later in the button click events.
How can I tell which control fired the postback while in page_init? __EVENTTARGET = "" and request.params("btnUpdate") is nothing
In 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?

When it runs, it successfully create a cookie thisVisit with today date as value.
However, when I reload the page, the cookie thisVisit becomes null.
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 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
I am using ASP button its working properly at client side but on server side its not firing.

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.
explain the diference between these Page_Init() and OnInit() events and when we should use which one?
View 2 RepliesI 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'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?
I m trying to load a new tab which should load WebUserControl2.ascx on button_clickbut I m coming across this eror: A Zone can only be added to the Page in or before the Page_Init event.I have a webpart in WebUserControl2.ascx which should load FeaturedControl.ascx.Well, i m getting the error when i click on button at :
Private Sub LoadTab2()
Dim uc2 As UserControl = CType(LoadControl("WebUserControl2.ascx"), UserControl)
tp2.HeaderText = "Tab2"
tc1.Tabs.Add(tp2)
tp2.Controls.Add(uc2)
End Sub
Where, tc is tabcontainer, tp is tab panel.
i 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?

A breakpoint is set on FillForm() and this method is called two times but I can't explain myself why this happens. I have client side javascript code, when the form is being send, the onsubmit method is also called twice... Where do I have to search?! Is it a (known) bug? Think I could get it to work with this Thread: [URL] But why is the event fired within the onblur-event when it's fired anyway??
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?
So I have an asp:Login field on my login page. However, I want to use a path for the create account url and the forgot password url. So I have to do it in Page_Load or maybe Page_Init. Regardless, neither option works, it simply refuses to modify the login form.
protected void Page_Load(object sender, EventArgs e)
{
string accountpath = Request.Url.AbsoluteUri + "/user/RequestAccount.aspx";
string forgotpath = Request.Url.AbsoluteUri + "/user/ForgotPassword.aspx";
lgnMain.CreateUserUrl = accountpath;
lgnMain.PasswordRecoveryUrl = forgotpath;
lgnMain.InstructionText = "test";
lgnMain.Focus();
}
protected void Page_Init(object sender, EventArgs e)
{
string accountpath = Request.Url.AbsoluteUri + "/user/RequestAccount.aspx";
string forgotpath = Request.Url.AbsoluteUri + "/user/ForgotPassword.aspx";
lgnMain.CreateUserUrl = accountpath;
lgnMain.UserName = "test";
lgnMain.InstructionText = "test";
lgnMain.PasswordRecoveryUrl = forgotpath;
}
In page-init, view state and some other components don't get loaded. Which are they?
Why do they loaded in Page-Load only? What does the need of Page-Init then ?
I am currently working on an ASP.NET project, where I am using C# as my default language. I have an .aspx page, where I have an AJAX Script Manager and an AJAX timer. When that page first initializes, it does a pretty costly operation (parses a .csv file), which I only need to do once. However, every time the Timer tick takes place, Page_Init is fired again. Is there any way to correct it?
View 12 RepliesI want to add event handlers programmatically to the server controls rather than using their predefined OnClick properties, etc. But which would be considered a better practice for defining handlers:
Define them in Page_Init
Define them in Page_Load
there is PagE_Load code block.Its okay.but If I add Page_Init codeblock, shoud Oninit method is necessary ?
protected void Page_Init(object sender, EventArgs e){
base.OnInit(e);
if so why ? and what may be problem if I wont add this line ? because If I add or not everything seems working.
I'm creating a page that users can upload a file to the webserver. After upload the page will then have a link to the file that has just been uploaded, along with any other files that have already been uploaded.As I am programatcially creating links to the files which have been uploaded, I have to do this in page_init or else the link button won't fire off it's event when clicked. MY web page does all this - it creates the link buttons and when I click on them, it calls the event method required i.e. a sub to download the file.
OK, the problem I've come accross is: when I click upload (to upload the file) - the page_init sub is called, displaying all the previously uploaded files as link buttons. Then my btnUpload_click sub is called, which uploads my current file. The only prob is the current file hasn't been displayed? I can only display links in the page_init, but because btnUpload is called after the page_init, the current file isn't uploaded until after page_init and therefore not dislayed?
I do some dynamic stuff with UpdatePanel controls and it would be great to store stuff in a Session key and be able to grab it immediately with confidence in a Page_Init. Fantasy e.g.,
If(!isPostBack)
Session[pageInstanceID + "ThekeyIWantAccessTo"] = "123";
else
locVarValue = Session[pageInstanceID + "ThekeyIWantAccessTo"] +"";
I want something like this so that even if an individual user has two or more instances of that page open I am able to respond correctly to the immediate instance in Page_Init. Is it possible to achieve what I want or some facsimile of same? I know I can speculatively make an assumption and then check it in Page_Load when I have access to ViewState, but I would like something that approaches a best practice.
When we double click to page It creates an empty Page_Load event codeblock automatically. Or you know can create other control's event subroutine events by clicking the relevant event in properties window.
but how can we create a Page_Init ? is there an automatic way ? or should we just write its name and parametes manually is the only way ?
