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?

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
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?

View 30 RepliesI 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?
We need to add 2 user controls to an aspx file, these 2 user controls have one telerik ajax manager each. but telerik only allows one ajax manager in a web page. I am getting exception while running the app.
Is there any way in aspx to seperate the user controls so that it will act as a seperate page?
First off - has any recent .NET / Windows Service Pack / Windows Update changed the behaviour around the Visibility of Panels / User Controls? An area of our site has all of a sudden stopped working. The most recent change that I made was a few weeks ago, I've backed out the change from my development environment, but the issue is still happening.
I'll explain what is happening. I have a couple of forms where the same behaviour is happening, but they follow the same pattern:
On the form there is let's say 2 ASP:Panel controls. In each of these there is a separate ASP:UserControl. When the User first visits the page, they are shown the first Panel and User Control. On this control they complete a couple of steps and click Next. This fires an event on the main page, which hides the first panel and shows the second panel, at least that is what is supposed to happen - and if I debug and step into the code this is what is happening as normal. Except on screen, the first panel is no longer being hidden, so it would appear clicking the Next button does nothing.
I'm at a loss as to what has happening - nothing has changed, and stepping through the code it's working correctly, but the screen is not reflecting what is happening in the code.
My next step is to create an isolated set of test pages to recreate the issue. Will attach when done and investigated, hopefully this will solve it
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;
}
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
I have implemented a user control with dropdown lists and textboxes where user may choose to add more of the same user control dynamically then submit the values within all usercontrols at the same time. They way I added usercontrols dynamically is whenever user clicks "add more" button, it increases the value of "userControlAmount" in session by 1, reloads the page and during next page_load event, within an updatepanel it creates usercontrols on the fly.
However whenever more is added since all usercontrols are generated again according to the latest user control counter, the values within the dropdownlists and textboxes are getting reseted.
I can hold all values in a viewstate/session however beyond the time/effort it will take, it doesn't sounds very "professional" to me. I was wondering if there is a more efficient way of doing this.
I was trying to add a Theme and some UserControls to a existing ASP.NET Web Project (nopCommerce) via a Second Web Project (which is added as an virtual Directory). But this did not work in my Configuration and I did not know if this is even possible.
The Reason why I want to seperate my Code from the nopCommerce project is for easyer upgrading to a new Version, and to handle adaptations for different shops efficient.
I have the usual problem of dynamically created usercontrols not hitting the event handler for a linkbutton inside the control, but I've checked the usual problems and I can't work out what's wrong. I'm calling a function to create the controls at the bottom of my page.load (although I did try page.init as well just in case) outside of my page.ispostback check, and I'm setting the controls id's to a fixed name which is consistent across postbacks. Any ideas what's wrong?

Usercontrol code:
<asp:LinkButton runat="server" ID="lnkDeleteGroup" Text="Delete this group" />

I have a simple user control which contains a textbox and a dropdownlist. I need to add this control multiple times to my page then save the details to my db, validating each control. When they re-enter my page I need to load the user control for each record in the db populated with the data they entered. They can then edit the data, delete the row or add new rows.
I'm trying to find the cleanest most efficient way to accomplish this. I realise I would need to re-add the user controls after each postback re-populating the data. Would the best way be to add each row to an arraylist or list of type object, save it to the viewstate and re-add the controls with data on postback, or is there another method which would suit?
I have a general question regarding usercontrols' parameters. In the built in web controls, such as the 'runat' parameter, when you begin to type 'runat' in Visual Studio, it gives you an Intellisense choice of 'server'. Or in the RequiredFieldValidator controls, the 'Display' parameter has 3 choices: Dynamic, None, and Static.
My question is, how do I incorporate this feature into my custom Usercontrols?
For instance, I created a usercontrol with a parameter called 'BorderColor'. This parameter will change a textbox's border color to the specified value. The possible values are: Blue, Red, Green, Black, Purple, etc. How do I have Intellisense display these choices when the BorderColor parameter is typed in?
I want to create several instances of a webcontrol on my web page each time the user clicks an 'add' button.
