IHttpModule.BeginRequest Firing 2X, Application_BeginRequest Firing 1X?
Feb 2, 2010
I'm running VS 2008 and .NET 3.5 SP1.
I want to implement hit tracking in an HttpModule in my ASP.NET app. Pretty simple, I thought. However, the BeginRequest event of my HttpModule is firing twice for each page hit. The site is very simple right now...no security, just a bit of database work. Should log one row per page hit. Why is this event firing twice?
Moreover, IHttpModule.BeginRequest actually fires a different number of times for the first page hit when running for the first time (from a closed web browser)...3 times when I'm hitting the DB to provide dynamic data for the page, and only 1 time for pages where the DB isn't hit. It fires 2 times for every page hit after the first one, regardless of whether or not I'm touching the DB.
It's interesting to note that Application_BeginRequest (in Global.asax) is always firing only once.

we are having some weird issues with URL Routing in ASP.NET 3.5.
We have a search box that does a search and redirects to a routed URL.
When we search for the first time (aka Press a button that forces a postback) everythign works as expected. we get:
1. BeginRequest event.
2. Determines Route
3. Calls Routehandler to match the route item to the actual destination page
4. Routes the url appropriately.
After you do one search successfully and try again it fails to call the BeginRequest event. Because of this the routing data never gets called and so the url is never routed to its correct destination. What is weirder still if we append a "/" (trailing slash) to the url after the initial postback it DOES work properly again.
So our search route looks like this
mydomain.com/Search
entering a term and pressing the SEARCH button would yield a result url like this:
mydomain.com/Search/Results/MySearchTerm
Going back (after 1 successful search) you then need to use this url or else BeginRequest will never fire:
mydomain.com/Search/ < (note the extra "/" at the end)
why the BeginRequest event never fires unless the slash is appended?

I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:
[Code]....
Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.

I have an ASP Button that I am creating in the CodeBhind of a Control. Here is the code:
Button SubmitButton = new Button();
protected override void CreateChildControls()
{
SubmitButton.Text = "Submit";
SubmitButton.Click += new EventHandler(SubmitButton_Click);
}
private void SubmitButton_Click(object sender, EventArgs e)
{
CustomTabs.CreateNewTab();
}
The Click event won't fire, though. It appears like it does a postback and never hits the event.

I have a page containing a datagrid, which works. On that page I have a button which is supposed to trigger a download of the data from the datagrid in Excel format. However, the button isn't firing the event. The C# code-behind I have is:
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
using umbraco;
namespace MyDataExport
{
public partial class DataExport : System.Web.UI.UserControl
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
GridView1.DataSource = BindData();
GridView1.DataBind();

I have the following Jquery function to notify the user with a prompt when they have unsaved changes (similar to how SO does it) and are trying to leave the current screen.
<!-- in my aspx page -->
<script type="text/javascript" language="javascript">
window.onbeforeunload = function()
{
if (HasPendingUpdates())
{
return "Changes you have made will not be saved.";
}
}
</script>
This works as expected and shows the message box when the user tries to click a href to browse away or use the back button etc. The problem I am having is that one of my links is a asp:LinkButton because it needs to fire off some server side code before leaving the page. When the user clicks this LinkButton they get the prompt twice.
Scenarios:
User clicks the LinkButton
Prompt appears and user clicks the cancel button.
Prompt disappears and user is still on screen. GOOD.
User clicks the LinkButton
Prompt appears and clicks the OK button.
Prompt disappears and the same prompt shows again.
User clicks OK again.
Prompt disappears and user moves to the next screen and all is good.
So why am I getting the second prompt??? How is the OnBeforeUnload firing twice?

I'm having trouble with IE8. The page works fine in Safari and Firefox, but in IE8, I can't get the Submit button to trigger postback - Async or Full. I tried registering the Submit button for Full Postback:
[Code]....
I've had to do this work around before in IE, but clicking the button seems to be doing nothing. I think there might be a JavaScript issue, but I can't figure out what it is - you'll notice the menu controls don't work in IE.

I have a web application that I upload an image to, the image is subsequently saved to the server's temp folder and displayed via a webhandler on the aspx page.
the code for the aspx:
<img src="PreviewImageQualityHandler.ashx" alt="Picture not loaded" runat="server" id="imagePreview" />
The code for uploading the picture and adding a unique id to the Session:
protected void uploadButton_Click(object sender, EventArgs e)
{
if (FileUploadControl.FileName.EndsWith(".jpg") || FileUploadControl.FileName.EndsWith(".jpeg"))
{
string tempFileName = Path.GetTempFileName();
[Code]....
My problem is that the webhandler only fires on the first image-upload. If I try and upload a new image, the webhandler never fires.
If I remove everything to do with Session from the webhandler it fires on every single postback, like it should.

I used Castle Windsor before and had this routine that fired the certain method of all classes that implement a certain interface.If I recall correctly, the interface was IBootStrapTask and only had an excecute method. Then, for instance, I'd place all my route registrations in one of these, and know it get fired on application startup.Have to admit I did not understand the code to well, so I'm even more unsure how can I do this. I'm using structure map now. (still knowing very little about it)

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.

Is anyone other than myself having issues with client validation not working all the time? I have MVC3 RTM installed. I'm looking at the LogOn view created with a new Internet Application with the razor engine. Both the User name and Password fields both have the Required attribute. If it enter asdf for the username and asdf for the password and go back and delete the values for both of them, only the error message for the password field comes on. If I keep entering values and deleting them, the validation will eventually trigger for the user name field.

I'm running a 2.0 .NET app on my local machine; the app uses Global.asax to trigger logic at both Application and Session Start. Up until this week, session management in this application was behaving normally. Now, after no apparent change to my system, it is not. The application has a sign-on screen at startup, in which the user selects a user profile, and proceeds to a main menu. The user info is stored in a Session object, and carried forward to the main menu for the remainder of the application. Normally, a new session is created when the user times out; however, I am finding now that, on my machine, a new session is created on each form change (Response.Redirect, window.open, etc.)
Web.config for the app, when testing locally, uses a <sessionState> setup of 'mode="InProc" cookieless="false"'. My IE7 browser is set up to "Always allow session cookies". When I attempt to run the app 'cookieless="true"', it works up to a point where a popup form is displayed, at which point a new session is created, and the Session_Start logic kicks in, where I lose my user info characteristics. This in turn triggers logic which assumes the user timed out, and a "Session Expired" screen is presented.
I do not have IIS installed locally; ASP.NET is used for session management. I have tried setting the timeout to an extremely high value, without effect.
