Profile that is used for ASP.NET Profile Service is not available in Page code behind files like in Page_Load.
It may be just a problem with Visual Studio installation/configuration, but as another problem, classes placed in App_Code in not seen in page codes. Even when I'm adding new ASP.NET folder to my project, "App_Code" is not available as an option.
I tested the entire scenario with ASP.NET Web Project and Empty ASP.NET Web Project. This problem does exists while creating ASP.NET Website.
Environment: Visual Studio 2010 Ultimate x64, ASP.NET 4.0, Windows Server 2008 R2 x64.

I'm trying to throw the exception back to Page_Load but the throw statement causes error: ArgumentNullException was unhandled by user code. How can that be fixed? Also, I can't see Label1.Text displayed on the page after the ArgumentNullException occurs because the page is not re-load. If there is no exception, it's fine to not reload the page. How can I see the Label1.Text displayed?
protected void Page_Load(object sender, EventArgs e)
{
try
{
...do something here...
}
catch (ArgumentNullException ae)
{
System.Diagnostics.Debug.Write(ae.Message);
Label1.Text = ae.Message;
Label1.Style.Add("visibility", "visible");
}
catch (Exception ex)
{
...do something here...
}
}
protected void ImageButton1_Click(object sender, ImageClickEventArgs e)............................

This is probably a really simple question, but I'm looking for a way of running a particular script on my website which will be ran every time a page is loaded. Basically it to work as if the script is in every .aspx Page_Load of my project.
I tried putting the script in the Application_Start event of the Global.asax file, however I noticed this didnt always run.

I have a class named PageBase inheriting from ASP.NET Page. I want to do something in PageBase's Page_Load.All pages in my application have their logic done on their Page_Load. I'm thinking of a way that Page_Load of both of PageBase and other pages run without having to override Page_Load in pages. Is it possbile?

I am having a problem with FireFox, I have an app using VS 2008 and it is using a Wizard control. Under IE the app only runs Page_Load once but FireFox is running it twice which would'nt be a big deal except the second time it is not going through as a post back so all of my setting are getting reset as if it was the first time through. I have see in previous post that the problem was autoEventWireup needed set to False, well mine is. I am using Ajax and UpdatePanel.

I'm developing an asp.net model -view-presenter (MVP), and to my surprise i see that when I click on the linkbutton in the window the Page_Load event is fired again. Is that normal? I'm used to webforms where we could just do a if (!Page.IsPostBack) if statement in the Page_Load. I did that but then no action happend when I clicked the linkbuttons in the window.

i have 1 master page with 5 pages that call it. now on the master page, I have few dropdowns and textboxes, and the calling pages only have a small article in the corner. I want to start a session on page_load event, so that if the user chooses to select a dropdown or put data in textbox, even if he clicks on the other 4 links of other pages, the data should stay.

<asp:Image ID="imgVerify" Width="60" Height="18" runat="server" align="absmiddle" Style="border: 1px solid #999999" ImageUrl="/Common/GetCaptcha.aspx" />
It'll also trigger Page_Load() of abc.aspx. Is this that true? And if it is, can I avoid it?

I have a gridview that normally loads when a user clicks a View Report button. However, I now want to show the gridview while the page loads.
I tried calling the following method from the Page_Load event:
protected void btnView_Click(object sender, EventArgs e)
{
try
{
grvReport.DataBind();
}
catch (Exception ex)
{
Master.ShowMessage(ex.Message);
}
}
but it didn't work. Also tried calling grvReport.DataBind() from Page_Load to no avail.

I have a couple of sqldatasources. One of the control's parameters is based on another's selection. How can I control which one selects first? Does this occur in code behind? Is there an event that I can set a sqldatasource.select() before the other one selects on it's own time?

I am trying to add controls on the page from the backend in the page_load stage. Here is my code:
foreach (FileInfo fi in dirInfo.GetFiles())
{
HyperLink hl = new HyperLink();
hl.ID = "Hyperlink" + i++;
hl.Text = fi.Name;
hl.NavigateUrl = "../downloading.aspx?file=" + fi.Name + "&user=" + userIdpar;
Page.Controls.Add(hl);
Page.Controls.Add(new LiteralControl("<br/>"));
}
The error which I am getting is on 'Page.Controls.Add(hl);' and here is the explanation: The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases. What can I do so I can fix this issue.

I have something like this:
bool preventEvents;
protected void Page_Load(object sender, eventargs e)
{
preventEvents = doSomeValidation();[code]....
EDIT:
got some interesting answers (thanks to everyone) but not what i was looking for, maybe i should be more specific:
given some condition, is it possible to skip all events after Page_Load and just jump to the rendering, without manually removing/mapping each event?

In my asp.net web application,I use IFrames to show another page inside one page.But the problem is that the page load event of the embedded page in the IFrame is not firing when the Iframe is shown by clicking on a button in the parent page.I use the IFrame's visibility is true/false to show or hide the Iframe.I am confused what is happening there.

I have a heavy aspx page with lots of controls that are loaded from sql server. I use the cache were I can.On my aspx page I have an asp:Button that allows members to rebuild the page with the new content selected in each control.The page build or page_load takes about 15 sec (say). If users select the asp:button before the 15 sec page_load is completed. Some times I get performance issues with my controls. I don't get errors as I am using cache a lot etc.
QUESTION1: How can I stop a page_load event firing before the previous page_load process is completed, how do I stop impatient users getting carried away with too frequent page loads firing from the asp:button?Can I do some codebehind smarts that can nullify asp:button event while a previous page_load is process is still a work in progress.
