My question is this: Do I need to include the statement that loads user preferences when I run the page method or are the statements in the Page_Load event triggered when the page method is called, and if they are, will the variable be populated?
Is it possible to call usercontrol methods/events using MSAJAX. I wanted to update my usercontrol by calling one of its events when a property from its parent page changes.

How do I create a new event in a base page class that fires after all derived pages have fired their load events but before any controls fire their load events.
The following code fires the event before the derived page's load event. I want it to fire the event after the derived page's load event but before all control load events:
Base Class:
Public Event FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs) Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not IsPostBack Then RaiseEvent FirstLoad(sender, e) End If End Sub
Derived Class:
Private Sub Page_FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.FirstLoad 'Stuff here happens before controls load but only on first page loads' End Sub

I am trying to use page methods to call a function and I am getting a "PageMethods is undefinded" error. I have used them before whilst using C# but not VB so I'm wondering if my syntax is wrong as all examples I can find are C#.I am also wondering if it's because my scriptmanager is on the master page?I've read about this error everywhere but everything I have appears to be correct!

I'm using ASP.NET page methods to check for the updates. I'm using inproc sessions and windows authentication in IIS 6. When page is loaded, a session is started. But sometimes when the page method is called it starts a new session(created with current request return true also). Why that might happen ?
I'm having problems with accessing querystring params in my page method. Everywhere I read it says you can access querystrings just fine, but when I try it just returns null, what's the problem?
I have got 3 aspx page and a usercontrol on each page have an email placeholder in it. What I want to acheive is when the customer click on the usercontrol email placeholder, certain method on a particular page should trigger. See below for the code:
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Text; using Tangent.Breakingfree;
[Code]....
Also I have got another method on a different aspx page, I want to trigger that method when the client is on that page. The user control should trigger the right method depending on the page user is currently on.

Is it possible to do something like this inline in an ASPX page?
<%= Me.SomeExtensionMethod() %>
I can't seem to figure out how to get this to work properly. I'm receiving an error saying that "SomeExtensionMethod" is not a member of the current Page object. I've added the necessary <%@ Import Namespace="..." %> directive at the top of my page. This Does work in code-behind.This isn't vitally important, but it would be good to know how to do in the future.
I know that when declaring a page method in ASP.NET, I can specify a CacheDuration like so:
[WebMethod(CacheDuration=60)] public static void Foo() {
But from what I understand, CacheDuration only supports absolute expiration. I want to have sliding expiration. So that leads me to believe that I need to access the System.Web.Caching.Cache object somehow. But, since page methods are static, and this is essentially a standalone web service, I'm not sure how to access it statically. The only ways I have seen on Google rely on getting it from the HttpContext. But, there is no HttpContext available to me here, right?Or, do I need to use the System.Runtime.Caching.MemoryCache to do my own caching?
I have a parent page with two data controls. I want to be able to open a child window, do something on it, and when it closes I want to rebind only one of the two data controls on the parent page. I have the control I want to update within an UpdatePanel so would like to call rebind it and call UpdatePanel.Update().
In my Home page I have a link to my Details page. When I click on the link it goes to the Details page Page Load Function like its suppose to, but when it finishes it goes back to the Home pages Page Load Function. Then loads the Details page. So it parses the old pages Page Load Function for somewhat no apparent reason, because in the end it loads the Details page. This only happens when I click on the link to my Details page. When I click on other links to other pages, it doesn't do this. For some reason only my Details page. I went through the code to see what could be causing this but have no clue. I included below the complete .aspx.vb for my Details page. What could be causing this? Again this ONLY happens when going to my Details page.
Here is my situation: I have a user control that has a menu in it. This user control sits on my master page. It is my main navigation menu for my application. I am having an issue where, on one of my pages, users seem to be leaving the page before committing all changes to the database, which results in a loss of data. So what I want to accomplish is - if the user is leaving this page and the data has not been saved yet, I want to prompt the user and say something like "The information is not yet saved, are you sure you want to leave this page" in a modal popup. So my approach is this: In my menu user control, create an event handler called MenuClicked that is raised when the menu web control's (in the user control) MenuItemClicked is raised, I raise my custom MenuClicked event. Then on my master page, I can catch this event in NavMenu_MenuClicked. My problem is - I need to catch this event in my content page, not the master? Am I approaching this correctly?
In my web form, i have 2 drop downlist controls. eg. dropdown1 and dropdown2. I will change the dropdownlist1 item, consequently selectedindexchanged event fires and reloads the dropdownlist2 items. And i have another button also in order to get the result based on the dropdown1 and dropdown2. Lets say for example, i have a list of countries in dropdown1 and a list of states in dropdown2. I selected "India" in dropdown1 and correspondingly "Tamilnadu" in dropdown2. And then click a button which calls the dataset based on dropdown1 and dropdown2. The problem i face here is, whenever i click on the button to load the dataset, dropdown1 value remains the same as the dataset is not called again, whereas the dropdown2 value changes to the first one as it gets called automatically during postback. For your information, I have loaded both the lists in the page load using (!IsPostback) property.
