User Controlcan Be Completely Self Contain?
Feb 17, 2011
I am trying to make a UserControl that have all data process, initialize data, ajax, all self contain into one control.So I can insert to anywhere on my Asp pages.But the problem is, the UserControl contains a Script Manager and the Page that contain that User Control has a Script Manager too, so Asp doesn't allow me to have two Script Manager in one page.In case like this, I wonder if UserControl can completely self contain?Or the proper way of using UserControl is just using it like a template, and all the data process, event handler I have to do on the page that contains the UserControl?

I have some logging that has to be done, which are some database update or inserts.
However this logging is of no importance to the user, so I only want to process the data/logs after the page is completed for the user.
As of now, if I process the data while the page is loading, I go from 1.4 to 2.0 speed (server side time processing of code), which is quite a bit comparing it is of no use to the user.
So I want this code only executed after that the page is complete.
I've been checking out Ajax, async pages etc, but the problem is it still gets executed before the page is rendered to the client, which means the client will have to wait longer then it is not being processed.
I've been checking out Threadpool.queueBackgroundWorker, however if I get it correct, this will still be executed before the page is shown to the user, as it has to complete before the prerender.
Then I thought about creating a new thread, and do the processing there, which would not have my page waiting to complete the data/logging.
However when I have 100 or 200 users loading pages at the same time, then that would mean I would be creating 200 threads on those loads, which I doubt will be good for performance. So if I want to solve this, I would have to create my own threadpool and only assign for example a max of 40 threads to it which can process the data.
All I want to get done, are some update/inserts into database after the page is rendered and shown to the user. I don't want the logging to slow down the pageload for the users obviously. I want that logging or no logging makes no difference to the pageloadtime for the user at all.

Technology: ASP.NET 4.0, C#, forms/mvc
I am a .NET web designer and I wish to create a modular based website for people, similar to what DNN does (but I want to create my own cut down version).
The idea is that I create a base website that can 'activate' features which the client needs (and has paid for). These features may be used by many clients which require frequent future updates for all clients (so I wish to keep upgrade time down to a minimum).
For example, I upload the base web application using web deploy and it sets up the core database tables/views/SPs in the process.Then I login into the website as developer and activate the out of the box features that I wish to permit the user to take advantage of. The only way I can think of currently is via user control, resources etc..But I need a little of your experience and advice over what the possibilities / dangers are....
e.g. images for an application e.g. blog, that I have activated for a client - how do I reference those images
e.g. Can user controls be dynamically added to a web application (which is pre-compiled unlike a website - it must be a web application since I am using web deploy).
e.g. Modification of web.config to add additional routing (doesn't matter if app has to go down to do this).
I can upgrade websites features en-mass, rather than manually enhancing each individual website which given a certain amount of clients would result in an awful amount of time lost.I do not have access to sharepoint (nor do I intend to). how to automate modularity completely via a front end in asp.net would be superb! how to reference files and resources outside of the websites directory and without using virtual directories

need to turn off the cookies in my ASP.net site completely
I'm doing some funky stuff serving images and scripts from a .aspx file, which causes the request to have cookies tagged to it.
So, how do I get rid of these?
I've tried setting the SessionState mode="Off" in the web.config, but that didn't seem to work.

Our current web portal at work was a port from a classic ASP codebase. Currently, all pages in our project extend a custom Page class called PortalPage. It handles login/logout, provides access to a public User object for the currently authenticated user, and adds the standard page header and footer to all of our pages. Every Page in our site is 100% designed in the codebehind. The ASPX page is not used at all. Every single div, img, and block of text is allocated as an object and added from a C# function, even if it is completely static content (which we have a decent amount of). Example for a page header:
HtmlGenericControl wrapperDiv = new HtmlGeneric("div");
HtmlAnchor bannerLink = new HtmlAnchor();
HtmlImage banner = new HtmlImage();
bannerLink.HRef = "index.aspx";
banner.Src = "mybanner.png";
banner.Alt = "My Site";
bannerLink.Controls.Add(banner);
wrapperDiv.Controls.Add(bannerLink);
this.Page.Controls.Add(wrapperDiv);
Even worse, all Javascript is added to the page as a giant mess of string concatenations:
ClientScript.RegisterClientScriptBlock(this.GetType(), "javascript", @"
<script language='javascript'>
fullUrl = '" + ConfigurationManager.AppSettings["fullUrl"].ToString() + @"';.............

I want to create a complete dynamic view engine in that absolutely all html content will be loaded from a database. This is so I have a templating engine that is totally customisable. I have something similar in classic asp and the way that works is with fillpoints so you have a master page html which will just be a string when extracted from the database and then content is dynamically added to the string to sections identified by a fill point. So for example I have my master page content loaded into a C# string and I want to load a main view and a partial view onto the page, how would you go about that in MVC? I guess I would have to keep the fill point idea as there is no other way to know where the content will go. I'm just after opinions from the community really on how to go about it.

What I have is a masterpage with some tables and contentplaceholders. What I want in some pages is that a table be removed because i have 3 columns on 3 tables and i need 2 columns only(so minus one table). Now i can access the table and give it some css through code but what i give is width:0 (and visibility:hidden if ever successful). The table contains one contentplaceholder inside a <td>. I can also access the td.The problem is that the table (thus contentplaceholder) will not go away.
It remains as entity as extending the second column will just push it downside(behavior expected when the column3 with contentplaceholder is present). So is there a way to remove the table holding the contentplaceholder?Only thought is to hide it and push it right that i admit i haven't tried it yet, I suppose it would be easier to make another master page but the problem is that i want specific designs on many pages so if this does not work i would either have to make many master pages or just use simple pages.

How to completely disable ControlState in an ASP.NET website application to get rid of <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/ACBDEFGH...XYZ=" /> on every page?
Searching for a solution, I only found meaningless answers making no difference between ControlState and ViewState, or replies saying that "we cannot disable control state". The second assumption seems to be false, since StackOverflow pages do not have ViewState hidden field.

I am trying to prevent VS from breaking on JS errors.
I have the following settings:
In IE, under Tools->Internet Settings->Advanced (tab)->Browsing
Disable script debugging (Internet Explorer) is checked.
Disable script debugging (Other) is checked.
In VS, under Debug->Exceptions->Common Language Runtime Exceptions JScript Exceptions (thrown and user-unhandled) are unchecked.
In VS, under Tools->Options->Debugging->Just-In-Time
Script is unchecked.
There are some JavaScript errors that I just don't care about and it is driving me insane having to deal with them.

I have a site that features some pages which do not require any post-back functionality. They simply display static HTML and don't even have any associated code. However, since the Master Page has a <form runat="server"> tag which wraps all ContentPlaceHolders, the resulting HTML always contains the ViewState field, i.e:
<input
type="hidden"
id="__VIEWSTATE"
value="/wEPDwUKMjEwNDQyMTMxM2Rk0XhpfvawD3g+fsmZqmeRoPnb9kI="
/>
EDIT: I tried both variants of setting EnableViewState on page level with no luck at all:
<%@ Page Language="C#" EnableViewState="false" %>
<%@ Page Language="C#" EnableViewState="true" %>
I realize, that when decrypted, this value of the input field corresponds to the <form> tag which I cannot remove because it is on my master page. However, I would still like to remove the ViewState field for pages that only display static HTML. Is it possible?

I'm doing css for a website. I send the html and css to a guy, he puts it into ASP.net. The problem is that the transfer didn't end well for my code and it needs some fixing. The problem is that when I look at it in Chrome, or Firefox, or IE8, I get three completely different renderings. I spent a good amount of time trying to fix a drop-down menu that is supposed to appear while hovering over a link. The one he had in place from ASP.net worked in IE, kinda worked in Firefox, and was completely broken in Chrome (I haven't tested Safari or Opera.) Just getting it to look basically the same in firefox and chrome was a struggle. The html source is showing me two completely different pages as well.
Does anyone have experience with this? I know nothing of ASP.net, and it seems like the guy is modifying my layout with a wsyiwyg (I found tables used in random places, which I did not put there.) Faced with this, what is my best option? Is this fixable, or am I in over my head?

I've written a desktop application using VB.NET and SQLEXPRESS. Now I am trying to deploy it to WS 2k3. But getting positive results wiht SQLE is proving difficult. Here is the connection string I am using:
connectionString = "Data Source=.SQLEXPRESS;" + "AttachDbFilename=" + DBPath + ";" + "Integrated Security=True;" + "Connect Timeout=30;" + "User Instance=True"
The problem is the results I get from the setting of 'User Instance'. Like it is, it loads a unique stance of SQLE, which is fine. But the instance just keeps eating memory. I tried limiting memory with sp_configure, but nothing happened. It just keeps growing. If I exclude 'User Instance', it uses the SQLE service running on my machine. It ignores the memory limitation, but eventually settles and stops growing.
Those results came from working on my local machine.When I put it on 2k3, I get the same results with User Instance = True; runaway memory. With User Instance = False, I start getting the 'attempt to attach an auto-named database failed' message. So now I am stuck. I would like to go with the 'User Instance = true' option, but I don't know how to deal with the runaway memory. If all else fails, I could use the =False option, but I just can't get 2k3 to allow.

I tried to figure out NHibernate (a first) First went through chapter 23 in Asp.Net MVC in Action 2, and read some articles to get the drift.
Then I modified the sample in the above book to work with my own database and my own table. Finally got that working. (Started messing with this yesterday afternoon....it's 7:30 AM, so .... I'm tired...)
Then I worked this into my own project (the shared mvc template some of you might have looked at).
Now my application became completely unstable. Sometimes it work, but other times it bombs out where my controller factory (Castle) set the component lifestyles:
[Code]....
Each time with some LoaderException that read like {"Could not load file or assembly 'Castle.Core, Version=1.1.0.0, Culture=neutral, PublicKeyToken=407dd0808d44fbdc' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)":"Castle.Core, Version=1.1.0.0, Culture=neutral, PublicKeyToken=407dd0808d44fbdc"}
Man I fiddled all over the place, having xcopy copy dll's (see krok.web properties got a post build event) and many other things I that does not really make sense.
And from the darned instructions, having all your dll's in a folder which get copied out to the web project's bin folder and dont know what else.
Seriously...if someone can download this and have a look (better not if you dont know Castle Windsor and NHibernate)

I created my own class from the HTMLEditor so as to be able to hide the hyperlink toolbar buttons but then discovered that if a user types in a URI, after typing a space after it the control automatically turns it into a hyperlink.
I'm working on a project where the client does not want users to enter hyperlinks at all and after a few hours of trying to decipher the controls javascript files, I cannot for the life of me find the code in there doing this.
Has anyone else run into this or can point me as to how to figure out where the code is so I can disable it?

I have the following code. What's happening is, on postback, the required attribute for sequence will fire. If it passed, the range check is skipped completely. If it fails, it never gets to the range check either. Have I coded something wrong?
using System.ComponentModel.DataAnnotations;namespace Venue.Models{ [MetadataType(typeof(CategoryMetadata))] public partial class Category { } public class CategoryMetadata { [Required(ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "sequence_required")] [Range(0, 9999, ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "sequence_invalid")] public int Sequence { get; set; } [Required(ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "title_required")] [StringLength(256, ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "title_invalid")] public string Title { get; set; } }}

I have a page which includes serveral gridviews, pulling out data from my datasources. At this stage, the parameters are set withing the page, however it will use a querystring at the end of the url. Once the page is loaded, i then have an Email function calling a HTML reader, which basically captures the content of the page and pushes to the body of the email and then emails it out.
The issue i am having is where to place this stagement. I have tried to insert the email function in the Page (load complete) event, but it still seems to send out over 20 emails, which to me, means that the page hasnt finished? loading and is constantly calling the email function.
At this stage, i need this page to load .. i cant think of any other way, i can get the data sent to an email without the interim medium; the page.
