Going "Stateless" And Loading Scripts Dynamically?
Mar 25, 2011
What I want to know is if I am approaching this from the right angle.
I have an asp.net app I am building. I am using a Masterpage for the overall look of the app (below you can see the code).
I'd like to have the menu system use a dynamic load like jQuery's .load() function to load the content. That is fine and I have that down. The .load() function uses innerHTML to pump that content into the page. This is a problem if on that page you want to load module specific scripts and styles.
My question is, in an environment such as this, how do you guys load your scripts for these modules? Should I load every script on the initial load of the app? This app will not ever be "that big" however I want to make sure I do it right just in case.
MasterSheet
<div id="primaryNavigation">
<ul>
<li class="current"><a href="../Default.aspx">Main</a></li>
<li><a href="../Modules/Page1.aspx">Some Overview</a></li>
[Code].....

the web should follow the REST principle and be completely stateless. Therefore a single URL should identify a single resource, without having to keep the navigation history of each user....and I read the Wikipedia page http://en.wikipedia.org/wiki/REST and it really sounds good, but I don't get how to actually implement it. I'm working in ASP .NET Webforms NOT MVC.
For example, in the application I am about to build - I need my user to Login before I allow them to do anything. There are a couple of hoops they have to jump through before they are allowed to do much useful - like Accept T's and C's and confirm their basic details are unchanged. Finally they are allowed to do somthing they really want like BuyAProduct!It seems to me (I come from the HEAVILY stateful world of the Rich client) that I need state to record what they have done and infer from that what they are allowed to do. I don't see how I can support them (say) bookmarking the BuyAProduct URI. When they arrive at the bookmark how do I know if they have logged in and if they agreed to the T's and C's and if they dutifully checked their basic details?
I love the idea of the app being stateless, partly because it seems to completely solve the problem of "What the heck do I do when the user clicks on the Back and Forward buttons?" I don't see how I can still get it to work properly. I feel I am missing somthing really fundamental about this.

I am designing an ASP.NET (3.5) web application that connects to a Rocket Software UniVerse database.
I am shooting for a RESTful design and a MVC pattern. Rocket provides a .NET library called UniObjects.NET which handles everything for connecting and retrieving information from the database.
What would be the best way to in general to log my users into the database, then use that session via connection pooling? I see that in 3.5 there is the ASP.NET Routing Infrastructure and that looks promising am I in the right direction on this? Also does C# support decorators like Python and Java?

I have the following code in my <head>
<% if(Context.User.IsInRole("Reseller")) {%>
<link href="<%: themelocation %>" rel="stylesheet" type="text/css" />
<%} else {%>
<link href="<%= Url.Content("~/Content/custom-theme/jquery-ui-1.8.5.custom.css") %>" rel="stylesheet" type="text/css" />
<%} %>
The issue is with themelocation, which is declared just above this block of code - like so:
<%
var reseller = new Reseller();
var storeSettings = new StoreSettings();
var themelocation = "";
if (Context.User.Identity.IsAuthenticated)
{
var resellerRepository = new ResellerRepository();
reseller = resellerRepository.GetResellerByUsername(Context.User.Identity.Name);
var storeSettingsRepository = new StoreSettingsRepository();
storeSettings = storeSettingsRepository.GetStoreSettings((int) reseller.StoreSettingsID);
themelocation = storeSettings.Theme.StylesheetLocation;
}
%>
Setting a break point shows that themelocation holds the string I need, but when the page is run - it generates a 400 - Bad Request error, and the net tab in firebug reveals its looking for this:
http://localhost:50982/%3C%:%20themelocation%20%%3E
Where am I going wrong here? Why is it using the variable name, and not what it contains?
I'm using ASP.NET MVC2, and all of this code is located on my master page.

Right now I've got a large .aspx page - starts out loading tons of .css and .js files...
Code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="AWCOffice.aspx.vb" Inherits="_AWCOffice" EnableViewState="false" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
[Code] ....
Then what follows is a large pile of javascript code - about 5800 lines of javascript code.
Code: <script type="text/javascript">
This is the main application. At the moment I like to keep it in the .aspx page because it's constantly changing and I don't want to worry about client caching and versioning.
After the JAVASCRIPT code comes the html - about 2000 lines of it.
Starts like this
Code:
</script>
</head>
<body>
<form id="form1" onsubmit="return false;" runat="server">
<div id="acs-system" class="acs-ddreflector acs-dddynamic">
<div id="acs-binder" class="noPrint">
[Code] ....
The DIV ACS-SYSTEM is the only visible area of this HTML.
The DIV ACS-POOL has a css style of display:none and holds template HTML that jQuery copies into the ACS-SYSTEM dom space as the app runs.
Here's the actual question.
Most of the 2000 lines of HTML in the ACS-POOL is customer specific - not all of my customers need all 2000 lines of this HTML. And as I add customers the nightmare of managing all this in one "SOURCE FILE" becomes daunting.
Never mind the wasted band width of giving all my customers all this HTML - even parts they do not need.
What kind of options do I have for breaking down and "dynamically" loading this in a more CUSTOMER-SPECIFIC fashion?
I think I could use jQuery to simply feed it from my "boot webservice" call - but if I can do it in a more HTML-fashion I would think that would be better.
I used vs 2008 for coding this and in my IDE here at the office I change the CONNECTION STRING in the web.config to point to different customer databases. Anything I can do in the WEB.CONFIG that the .aspx page can pickup???

If I run below ASP.NET code, it gives me same output in different post-backs. First Time
Name is = Smith
also After Post-back (Button Click)
Name is = Smith
I feel though I have defined singleton, it should return a new object every time in different ASP.NET post-backs. because once the function "PAGE_LOAD" is completed then there are no reference variables holding singleton object. So there is a change of unloading the singleton class from memory by CLR. that means there is a chance of losing private static reference variable and also single ton object stored. In ASP.NET stateless environment, why is it keeping earlier object in multiple post backs and btw, without having any reference variable to that object. Is this is known danger with singleton in ASP.NET environment?

When I was localizing my web application I got one strange doubt.
In the first request i set current thread's current culture to user chosen culture. It worked fine for that particular request. But when i browsed for other page, server rendered content in default english culture. I think the reason meight be "http is stateless" means current request is served by a thread whose culture was set properly. Send request will be serverd another thread which does not about previous thread. So we should once again assign culture to this thread. Localization can be done by setting culture to a session variable.
So my question is what is the benifit that we get by setting culture to current thread. With setting to thread we can show the page in user desired language.

I would like to load UserControl dynamically from DLL in the bin directory.
The dll contains several usercontrols which dynamically create webcontrols within them.
I do not have Virtual Path of the UserControls to use in LoadControl(String virtualpath) and LoadControl(Type, object[]) does not work(why the heck is it there in the first place anyways).
provide me some sample code which takes either the path of dll or assembly name "ServerControls" to load usercontrol "UserControl1" dynamically into placeholder "PlaceHolder1"

So I'm trying to dynamically load a usercontrol into a placeholder in another usercontrol inside a updatepanel.
basically I've got this markup:
<asp:UpdatePanel ID="upPopup" runat="server">
<ContentTemplate>
<UC:Popup runat="server" ID="UC_Popup" />
</ContentTemplate>
</asp:UpdatePanel>
And then this markup inside that usercontrol (Popup):
<div id="modal">
<asp:PlaceHolder ID="phPopupPlaceholder" runat="server"></asp:PlaceHolder>
<asp:Label ID="lblModal" runat="server"></asp:Label>
</div>
In the codebehind of the popup usercontrol I have:
public void Show(UserControl control) {
this.phPopupPlaceholder.Controls.Add(control);
this.lblModal.Text = "Loaded";
}
And I call this show method elsewhere with:
Popup.show(new MyUserControl());
Nothing loads into the placeholder though.
But in the show method I can load regular server-controls fine like this:
this.phPopupPlaceholder.Controls.Add(new Label(){ Text = "Label!" });
Can anyone explain to me why regular controls are loaded fine, but my usercontrol isn't loaded?

On a dashboard page I'm loading several controls dynamically; the controls always need to be loaded so there is no if (!Page.IsPostBack) code. The problem though is in that in the code-behind, we are using Request.Form.GetValues and a particular dropdown field's value is always null (presumably because the controls are being cleared and reloaded on a postback) and this is triggering an error later on in the page that expectes a value from this dropdown. I have to use Request.Form.GetValues because the page enables dynamically adding rows (each row containing 5+ HTML inputs) via Javascript.
If I check for postback, then the button event of the control does not fire at all but instead the dashboard page is reloaded, and no controls are loaded at all (i.e. the page is blank).
How do I get around this issue? I need to dynamically load the controls at all times, but I also need to retrieve the values via Request.Form.GetValues.
EDIT
Here's what the code looks like, roughly:
(Client-side HTML)
<table>
<tr>
<td align="center">
<select id="Class1" class="txtboxcomm" name="Class1" runat="server" />
<a href="javascript:classFinder('1')"> Look Up</a>
</td>
</tr>
</table>
<div id="action">
<asp:LinkButton ID="ibtnGetQuote" runat="server" OnClick="ibtnGetQuote_Click" CssClass="getQuote" AccessKey="G">Get Quote</asp:LinkButton>
</div>
(Server-side, in ibtnGetQuote_Click - this is actually a loop since user can append multiple rows; "i" is appended to the word "Class" to find the exact row)
IList<string> classes = this.GetFormValues("Class1");
// This will return null all the time...
private IList<string> GetFormValues(string clientID)
{
String[] values;
values = Request.Form.GetValues(clientID);
if (values == null)
{
Control ctl = FindControl(clientID); // uses built-in FindControl method
values = Request.Form.GetValues(ctl.ClientID);......
The original code was hardcoding the "ctl00$xx$xx" stuff, but the control may or may not be loaded so we cannot guarantee the name the control will get. In fact, I'm not even sure if this will work for all scenarios since only the FIRST control is a server control, the rest are just standard HTML controls so wouldn't have a "ClientID".

I need to dynamically access some SQL tables hopefully using the Entity Framework. Here's some pseudo code:
var Account = DB.Accounts.SingleOrDefault(x => x.ID == 12345);
which will return me an Account object and this contains some fields called "PREFIX", "CAMPAIGN ID" and further information about the accounts are stored in separate SQL tables with the naming convention of PREFIX_CAMPAIGNID_MAIN.
The tables all have the same fields so I was thinking of creating a new Entity that isn't mapped anywhere and then dynamically loading it, like so:
var STA01_MAIN = new MyAccount(); // my "un-mapped" entity
DB.LoadTable('STA01_MAIN').LoadInto(STA01_MAIN);
I can now get anything about the STA01_MAIN account: STA01_MAIN.AccountId. So my question is: how do I access these tables using the Entity Framework?

I am loading a series of controls in the Page_Load event. However, I have to recreate those controls each page load, which means storing their data elsewhere. This is cumbersome.
protected void Page_Load(object sender, EventArgs e)
{
MyControl control = (MyControl)LoadControl(...);
control.Initialize(GlobalClass.controlData);
//^gives the control the data it had previously.
//Or use ViewState["controlData"] if serializable.
Controls.Add(control);
}
I feel like I should be using if (!IsPostBack) {}, but I don't know how, or why. In contrast, if I place the controls into the markup, then the controls seem to stay persistent. For example, a button in mark-up will remember any changes to its Text property (I think?).
<asp:Button ID="buttonText" runat="server"
Text="Text Segment" onclick="buttonText_Click" />
How do I maintain some sort of persistence with dynamically added controls, like controls added via mark-up? This would save me much work and frustration.
(I've coded for a small eternity, but the more I do ASP.NET, the more confused I become. Which is exactly the opposite of what how I understood learning to work :-P.)

I am trying to create my own website management framework similar to DNN/SiteFinity (only a mucho cut down version).
One of the big (but common) features is to be able to dynamically add user controls to provide additional functionality.
I would prefer to use a pre-compiled .NET "Web Application" over a dynamically compiled "Website".
What are the implications of using LoadControl method to dynamically add a user control for a pre-compiled web applications with specific regard to:
Session (preume I am using the stateserver)What happens to all the other users - will they be logged out?
Application pool recycling due to changes to some compilation??
I am not sure I have ever dynamically added a user control to a pre-compiled web applications as I have mainly been using "Websites" so I am making a large presumption that it will work because if the website is pre-compiled, does this mean the dynamically added user control will be dynamically compiled as required even though the site is pre-compiled?
EDIT
I also forgot to mention that the user controls will be outside of the application directory and so won't be published during web deploy - they will be uploaded via another website.

The web page I am trying to (slowly) build should allow users to add whichever user controls they want on their page, and order them whichever way they like. This is saved in a database.
So each user could have a different number of controls on the page.
This is the design code, at the minute the user controls are fixed and are not loaded dynamically. They user controls are stored in 'blocks' which look like widgets on the page and can be dragged about to different columns. For each user the layout is stored in the DB i.e. which blocks are in column 1 and which blocks in column 2 etc.
How could I change this so that it can create a 'block' div for each user control returned from the database and put the user control in that block and in the right column?

I am using ASP.Net 2.0 with Ajax.
I am working on a pretty heavy page in an application and the scenario is:
There is a Tab control in the page, having four tabs. These tabs individually consist of different user controls and other asp controls. Most of these usercontrols in turn consist of other user controls. Every user control contains huge javaScript functions which validate them, populate controls and call web services.
What I am trying to achieve is to load only the Tab and its user controls on the page load and when the user clicks on a specific tab, load its contents (User controls) dynamically. Once that is done, I am setting the tab's postback to false to prevent loading it again once loaded.
I tried to achieve this by making the user controls in the other tabs - visible="false" in the markup and loading them from server side on some specific event. But that causes the javaScript functions in those user controls to give errors ('Object expected') when I go to that tab.
If I set the user controls in the other tabs to visible true, then no matter what; the page life cycle goes to each registered control and loads every subsequent control in that web user control which makes the main page slow (on loading and every postback).
The position of the Tab and the inner user controls is fixed. Although I am taking care that no data is populated unnecessarily on the page and user controls on hidden tabs, I dont want the tabs to get loaded altogether unless requested. If I load them on runtime, their corresponding javaScripts start giving errors.. note that I am not generating the controls on runtime, they exist in the page design. I just dont want to load them dynamically
