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.
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???
i would like to load a banner on to the page based on the registration count we have in the DB. if the registration count is >70, i will have to load banner2 on to the page. i am doing like this On the webForm.aspx
The above code works. is it Good Programming to load html files from codebehind? is there any alternative way? how does this impact when internet speed is slow?
I will be getting data through wcf service coming form commerce server (instead of DB). Data which is coming will be in the form big html content with all html tags or may be a single line sentence. I should display this dynamic data into the placeholder in the content page (master content page). I have been trying but not able to load when the data is in the form of HTML page. html content or may be single lline of senetence.
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:
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"
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.
(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 want to load the partial views when I click on the hyperlink, in my case I am loading both the partial views and then I am showing or hiding depending the parital views.
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?).
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 Master Pages for my site(VS-2005). A page in my site gives user information about a city which he has selected from a drop down list. I want that when a user selects a city's name from a drop down list control, then a particular HTML file of that city should get loaded into that page. The ASP.NET page should remain same but only loaded file should change. If a user has chosen London then the HTML file of London should be loaded, if the selection is Paris then XML file of Paris should be loaded in the same Page. How can I do that ?
I have a website where I'm trying to use an HTMLEditor to allow users to alter the body of email text. The text is stored in a database and looks like this:
[Code]....
I load the current email body into the Content property of a new HTMLEditor.Editor object. When it loads the HTML, though, it looks like it does above; it doesn't "process" it. Can the Editor process the HTML?
Also, when I do edit HTML in the object and submit, the Editor's Content includes "<" instead of "<", etc. Do I have to manually deal with that?
I have a HTML file which I want to load, say in a Label control. This HTML file have a series of unordered list, which acts as a vertical menu links for the various sections of the file.Now, I have no idea whether these links, inside the HTML file, will work if I load it on Label control. Is there any other way of doing this ? I want those links to work when the file gets loaded.
I can't figure out how to get the legend to populate all the "strReason" and get the correct percents to show for each column. This is where I'm at right now.
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
Situation: I have a drop down list which I need to pass on to a webservice on button click. I am using Sys.Net.WebServiceProxy.Invoke to make webservice call.
Everything is happening inside a usercontrol which loads on runtime using dynamicpopulate extender.
I get following error:
Sys.InvalidOperationException: Cannot serialize object with cyclic reference within child properties.
Situation: Usercontrol also has a listview which is bound to dataset. However on calling listview.DataBind() in side the webservice method.
I get following error:
The ListView control 'ProductsListView' does not have a naming container. Ensure that the control is added to the page before calling DataBind.
There is no problem when call to service method is parameter less and listitem is not bound.
