Page_Init, IsPostBack always false
It seems the page has not yet figured out its postback mode in the Page_Init event. It is always false, even when it is true in the Page_Load event.
I need to know if the page is being posted back or not in the Page_Init event. What is the most reliable way to determine this? I am currently interpreting "Page.Request.Form.Count > 0" as "IsPostBack = true" and it is working. Is that the best way? I don't want to use a session value, and obviously viewstate is not loaded yet.
I'm wondering if you are looking for simply

Hi,Recently I made some changes to a site that was working fine. After these changes were made the Ispostback value is always false and this has mean't loss of events firing. After days of searching google I can't figure out what went wrong. The viewstate is enabled in the masterpage and web.config. What sort of debugging steps should I be taking to hunt down this problem as I can't pin point it to a specific change that I made and I am pretty sure the viewstate (or lack of it) is the problem .

When I refresh brower window (using refresh icon on the browser), I found out from running in VS Debugger that IsPostBack is set to false every time the screen is refreshed.
I want to do some database initialization when when the page is displayed for the first time.
Can someone please shed some light on this problem?
Actually this is not a problem - refreshing the page is different than posting back. Post backs are caused by the controls you place on your form.

I'm desperately trying to find an AJAX control (I don't care if it's currently for ASP.NET AJAX.NET, since if not, I'll do the conversion and make it available to others) for creating blogs and another inline editor control, so that if there is text on the page, I can click on the text and it will automatically display an editor and allow me to edit the text/html.
Does anyone know of a control like this that's AJAX enabled? Especially AJAX.NET. I'm only interested in open-source, since any improvements I make I will make available on codeplex.com
Thanks in...Web farm load balacing resulting in IsPostBack always == false?
Ok, got two web servers that are basically load balanced between. Application works just fine in single server environment. Also, if I'm lucky enough to post back to the same server in load balanced environemt everything also works fine. The problem starts when I end up posting back between servers. I've confirmed I am running the same .NET version, same exact application version, same machineKey settings, etc. on both ServerA and ServerB.Basically if you've done any research on this stuff before you know that the first thing the page stuffs in it's ViewState is the result of Page::GetT...IsPostBack is correct in Debug Mode but always False at run time!
I was testing a very simple page with nothing but just a form and a button. When run in debug mode, ie F5 from Visual Web Developer 2008 Express, IsPostBack seems to return the correct value whether it's the initial load (false) or when I have clicked the Submit button (true).
But if I compile it and run it from the web, IsPostBack is always false!
What have I done wrong? The code is as follows:

I have a ASP.net Grid control inside the Updatepanel with ChildrenAsTrigger=true. Clicking the Grid's button field (RowEditing) causes async post back but in the Load event if I check the Page.IsPostback it gives false.
While another Update panel's async post back sets Page.IsPostBack to true.
The only difference in both update panels is the first one's post back caused by a Grid's button field and the second one's post back triggered by a drop down inside the update panel. Async post back for both are caused by controls inside same update panels.

I got this form with several panels and buttons to go back and forward. I initiate a variable inside the page_load, like this:
dim s as integer
if not ispostback then
Somehow, whenever a forward button or previous button is clicked, it will execute s=0. I followed each step and it looks like ispostback is always false in this case. Any suggestions?
dim s as integer
s is never given an initial value, so, it's default value is 0, even on a postback.

...Does the AJAX Control Toolkit always use AJAX?
I have not seen this question answered anywhere yet, but does anyone know if the Control Toolkit always uses Async postbacks for all its operations. For instance the hovermenu or filteredtexbox, for example, should not need to do an async postback. As far as I can see the hover menu does not, but i could be wrong. Does anyone know if this is the case and if so do you know which controls do not postback?
We don't have this information compiled anywhere, but it's generally simple enough to tell from having a look at the code. FilteredTextBox, for example, doesn't do any postbacks of any...
