Postback - Multiple Page_Load Events With URL Rewriting?
Feb 18, 2010
Im using intelligencia urlrewriter as my url rewrite module. I have one very strange problem which only occurs when an url is rewritten but to make it more fun, not on all rewritten pages. Edit: Forgot to tell you what's the problem boing boing. the problem is that my Page_Load event gets fired 2 times.his is how my form rewrite adapter looks like:using System;
using System.Web.UI;
using System.Web;
using System.Web.UI.WebControls;
[code]...

've recently set up an ASP.net site (not using MVC.net) to use URL Routing (more on the code below) - when using user controls on the site (i.e I've created a "menu" user control to hold menu information) the page_load event for that control will fire twice when URLs have more than one variable passed over.
i.e.
pageName/VAR1 : will only fire the page_load event once.
while
pageName/VAR1/VAR2 : will fire the page_load event twice.
*Multiple extra VARs added on the end will still only fire the page_load event twice*.
Below are the code snippits from the files, the first is the MapPageRoute, located in the Global.asax :
[code]....
Note, that when I'm just hitting the page and it uses the default values for items, the reloads do not happen.

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?

I'm using a .js file to bind events to controls. I'm also using UpdatePanel to do async postbacks; however, when they postback,the controls lose the events that were initially bound to them. Is it possible to rebind the events in the Page_Load function by using the .js file?

asp.net 4.0 vs2010
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've got a weird problem with a NullReferenceException on a high traffic website my company hosts. The exceptions are logged with full stack-traces but I am unable to reproduce it.The exception occurs a couple of times a day, for different users, and it's a NullReferenceException thrown in the code block below:
protected void Page_Load(object sender, EventArgs e)
{
...
if (!Page.IsPostBack)
{
...
this.ViewState[StaticClass.StaticStringProperty] = StaticClass.StaticIntProperty; // this is the line the exception occurs on
...
}
}
The only place I can figure that a NullReferenceException would be thrown is if ViewState is NULL, but I've never known that and can't find any reason why this would be the case in a Page_Load that isn't a postback.StaticStringProperty and StaticIntProperty are both initialised, static properties of StaticClass.
StaticStringProperty is defined as:
public const string StaticStringProperty = "IdFromClient";
Does anyone know how this could happen, or any other reason why a NullReferenceException would be thrown on the above line?
EDIT.As requested, the full stack-trace for the error is as follows. Line 54 is the line I've highlighted above.
at MyCompany.MyApplication.Appliance.Page_Load(Object sender, EventArgs e) in C:Documents and SettingsshellamaMy DocumentsMyApplicationAppliance.aspx.cs:line 54

I have a form which inserts data in DB on Submit button click but the problem is when client click the button multiple times its sends multiple create requests means multiple button click events for the same time of same data, which must not be.
I tried to disable the button when client click the Submit button first time but after this it does not call server click event handler or not fire the server click event once it got disabled.
How to handle this multiple click problem..
I used the following code to disable the button

I thought that Page_Load events executed every time a page was loaded not just the first time. Am I wrong on this?
I have a Page_Load event that writes text to a label to display on the screen: Output.Text &= "Welcome to my Website <br />" (Output being the ID of a Label control)
I also have an On_Click event for a button to display the same information: Output.Text &= "Welcome to my Website <br />"
After clicking the button, I expected to see the output twice. Once for the page being reloaded and once for the click event. I thought that Page_Load events executed every time a page was loaded not just the first time.

I have a page with a drop-down. Based on the selection in the drop-down, data gets loaded and populates a RadGrid. I am using a custom user control for the EditTemplate, so I can't use radGrid.DataBind(). Instead, I have to use radGrid.MasterTableView.Rebind() in association with a NeedDataSource event handler.
My problem is that when I load the page initially, I populate the drop-down and automatically select a value (first item in the list) which triggers the databinding on the RadGrid. I can step through the code in debug mode and see that the grid is being populated with data, but when the page displays, it doesn't get rendered. When I then manually choose an item from the drop-down, which triggers the same grid databinding code, it displays properly the second time.
How do I get it to display the grid the first time the page loads?

My WebApp is part CMS, and when I serve up an HTML page to the user it typically contains relative paths in a.href and img.src attributes. I currently have them accessed by urls like: ~/get-data.aspx/instance/user/page.html -- where instance indicates the particular instance for the report and "user/page.html" is a path created by an external application that generates the content. This works pretty reliably with code in the application's BeginRequest method that translates the text after ".aspx" into a query string, then uses Context.RewritePath(). So far so good, but I've just tripped over something that took me by surprise: it appears that if any of the query string ("instance/user/page.html") happens to contain a plus sign ("+") the BeginRequest method is never called, and a 404 is immediately returned to the user.
So my question is two-fold:
Am I correct in my belief that a "+" would cause the 404, and if so are there other things that could cause similar problems? Is there a way around that problem (perhaps a different method than BeginRequest)? Is there a better way to preserve relative URL paths for generated content than what I'm using? I'd rather not require site admins to install a 3rd party rewrite tool if I can help it.

I am currently developing a solution in which the user logs in once and can work on multiple customers at the same time on my site.I've looked at all possible solutions involving sessionid having stored the customerid, to launching a new browser session so i could have multiple sessions for one users etc. I also looked at using cookieless sessions.But the all fail because it's not a simple solution and in my opinion a simple solution is most of the time a good and predictable solution.
Therefore i came up with the idea to use url rewriting(i've seen this used in other applications). When the user opens a customer, i would like to start his url as follows "~/Customers/xxxxxxx/*.aspx" where xxxxxx represents the customerid. and *.aspx represents a complete subset of pages of my site. This would allow me to use a simple technique to use multiple user sessions within a single asp.net session.
Now coming to my problem, I have never done some url rewriting, therefore my questions:
- Is this possible.
- Can i protect all the pages that need a customerid as input(come to think of it, if no customerid in the querystring, redirect to a selection screen would be sufficient).
- How do i adopt all urls used in a sitemap etc in a structured way.

I have my own Control1 which is dynamically added as child control to Control2 which implements INamingContainer in CreateChildControls() of control2.
Control1 itself implements IPostBackEventHandler. But RaisePostBackEvent() method is never called on Control1, despite I do call postback method from JavaScript.
And yes, there are other controls which implement IPostBackEventHandler interface on the page.
What could cause the issue?
UPDATE: Control1 is always created exactly the same way and assigned exactly the same ID in Control2
it looks like this in Control2:
protected override void CreateChildControls()
{
if(!this.DesignMode)
{
Control1 c = new Control1();
c.ID = "FIXED_ID";

I am creating a ASP.Net server control to manage locations. The control is a composite control containing several text-boxes, labels, and a link button. I use the AJAX Control Toolkit to provide a modal popup which contains a Bing map. All the Javascript is in its own file and used as an embedded web resource.
The link button is what opens the modal popup. It also needs to call a Javascript function that initializes the Bing map (onclick = "GetMap();"). There are instances when this server control is placed within an Update Panel (and there is no way to avoid this). When in an Update Panel the link button loses its onclick event. I understand that this is because during an async postback the portion of the DOM that defines the content of the Update Panel is thrown out and reinitialized, resulting in the event breaking. When the control is not in an Update Panel everything works as intended.
I have tried registering events on Page.Load and Page.Init, like so:
[Code]....
I have also tried flat out writing the function call to the page:
[Code]....
I have put breakpoints on the lines inside each delegate and they do not get hit. I am not aware of any special way to register events of a composite control's child control or the Page.Load/Page.Init events when being done inside a server control. Is there some special way to register these events? (Note: Both those code blocks above are in my CreateChildControls() method)
Below is the GetMap() Javascript function. As you can see it is pretty straight forward.

First of all, I am creating a something like a client/server solution using a standard ASP.NET website - I do know this method is not adviced, and most people would love to scream "COMET!" or "HTML5 Sockets!" - but please don't ;-) !
What I am doing...
I am creating an MMORPG on a website.
I have several clients whom need to be in contact at the same time. This is done by a global object in the Application scope.
My problem
I need to invoke an event to several clients. For instance, when an attack has been performed, I need to update some graphics. The attack logic is resolved in the global object, but each of the clients has to respond to this.
Right now I do the following:
fightTrace.Reciever.InvokeMoveEnded(this);
fightTrace.FiredBy.InvokeMoveEnded(this);
(This is a kind of observer pattern)
What now happends is a race condition. The one who loads the page_load event will get both of these events, and the one who is not running them, will experience no changes in the UI.
So what is it I really want?
What I really need is some genuine and nice way to create an observer pattern through the application state. I need to send an event out to every "listener" which is in this case is a client, and then do some update.

I have a masterpage setup, with a pageLoad in the topmost masterpage, which calls pageLoad2 for nested masterpages which calls pageLoad3 for content pages.
In my content page I have a jquery click event and in my nested masterpage I have a web user control.
Whenever I use the user control in the nested masterpage, it rebinds the click event in the content page (undoubtedly because the pageLoad3 is called again), but this makes the click event fire twice on a single click. The problem gets worse the higher up masterpages you go (eg. fires 3 times if user control from topmost masterpage is called).
how to make sure it only binds the jquery events once?

I am trying to incorporate AJAX in my web project for the first time and it isn't working. I don't know how to instantiate a class once and use AJAX to update the dataset numerous times before updating the database changes using a postback.
My project is to learn AJAX with a class object. Clicking the button is supposed to increment a count by one using a class to store the count. Here is my class:
[Code]....
Here is my HTML code:
[Code]....
And here are my button click event code snippets:
[Code]....
My problem is that as I step through the code (after clicking on the second button) it instantiates a new class object each time which returns a value of 2 every time. I have tried to fix the problem by putting my counter class instantiation in the pageload event using "If Not IsPostBack Then ..." but my probem there is that the button click event block of code would not recognize the cCount class - it put the blue lines under the cCount
My goal is to have the class object available to multiple events in the code behind: especially using AJAX to build records in one of my DataSet tables Does anyone know how to handle this?

Since i have 5 buttons that pretty much run the same code, except for the database updates, i found some examples of how to do this.. so i created 1 button event, and put my general calc code then some if statements to determine what button was clicked.. but doing this now i get a NullReferenceException
and here is the code its complaining about, why would this work within the other button events, but not this one? Ive compared and and all the buttons on the page are the same with the except of the database entries.
Button b = (Button)sender;
Label tfive = (Label)FormView1.FindControl("five");
Label ttwo = (Label)FormView1.FindControl("two");
