Automatically Attach To The Lifecycle Of ANY Server-enabled HTML Tag?
Dec 30, 2010
If a "server-enabled" HTML tag is in a Web form, like this --
<p runat="server"/>
-- is there any way for me to attach to its rendering? I assume once they have runat="server", they must have a lifecycle of some kind.I'd like to attach some code to the rendering of any HTML tag so enabled. So, whenever a template author puts runat="server" on a tag, I can catch the PreRender (or anything else) and execute some code.

am using Visual Studi 2005 and asp.net 2.0. when i run the project then IE is running and i can see the output on browser, but i cant debug it because by default it is not attaching wed dev. so every time i have to go Debug menu and select Attach Process, instead of this how can we set VS will automatically attach the process.

I need to capture the amount of time that ASP.net takes to execute each page request in my application, but I need to exclude any network latency. I am currently capturing render times by using the StopWatch class and starting the stopwatch during the OnInit method of the page lifecycle and stopping it after the Unload method completes. It seems that the Unload method includes the time it takes send the request to the client, thus including any internet/network latency. What is the last possible point I could stop the stopwatch in the Page Life Cycle that would not include the time it takes to send the request to the client. Would it be directly before the Unload event?
Related question: Does ASP.net finish building the response before it starts sending to the client? Or does it start sending asynchronously, while the response is being formed?
I am using ASP.Net 2.0 with IIS 5 currently.
I have this code in a class that all of my pages inherit from:
readonly Stopwatch _serverExecutionTime = new Stopwatch();
protected override void OnInit(EventArgs e)
{
_serverExecutionTime.Start();
base.OnInit(e);
}
protected override void OnUnload(EventArgs e)
{
_serverExecutionTime.Stop();
base.OnUnload(e);
}
UPDATE
I tried capturing the execution time at the end of the OnRender method, at the start of the OnUnload method and at the end of the OnUnload method. In all three cases the difference in times was at most 1 millisecond. Even when testing this from a client in Europe to a server in the USA, the times were identical.

So far, I've seen (and I'm using the following) scripts to show/hide a div or other controls depending on another control in ASP.NET
$('[id$=myRadio_0]').click(function() { $('[id$=myDiv]').show(); });
$('[id$=myRadio_1]').click(function() { $('[id$=myDiv]').hide(); });
and of course, my div in html like
<div id="myDiv" runat="server" visible="false">
and that works fine when the user selects either option of the radiobuttonlist. However, when I assign that radiobuttonlist a value of 1 or yes on my Page_Load on code behind, that isn't (and probably can't be) caught by jQuery, and my div remains invisible even though the control has a value of Yes/1. So, do I need to set the visibility of that div from code behind, or is there a way in jQuery to force a scan of these dependencies after i've set the values for the main controls in code behind?

I developed a asp.net app on my development machine using VWD 2010 and used a SQL Express 2008 database.
I've moved my app to the production web server. I have a separate database server running SQL 2000 Enterprise that I would like to use for my production data. I've detached and copied my .mdf and .ldf files from my development/sql express box to the production/sql enterprise box and have tried to attach them in the enterprise manager but I get an error "Error 602: Could not find row in sysindexes for database ID 19, object ID 1, index ID 1. Run DBCC CHECKTABLE on sysindexes." and the attach process fails.
What do I need to do to use this 2008 express database on an 2000 enterprise server?

In Server Management Studio, I am attempting to attach a database. After selecting the database in the wizard
I receive an error: This file is in use, Enter a new name or close the file that's open in another program.
I don't have SSMS open, and have restarted the computer to make sure the memory is cleared. Not sure what to try next.

Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' <!DOCTYPE html PUB'.
There are tons of references for this error message on the Web, but I can't figure it out. The problem is that the application works fine when I run it locally or when deployed to other servers. There is just one server where I get this error during a post back from an Update panel (it is supposed to populate and open a popup panel). There is no Response.Write() anywhere in the code and the other either. I think. The next thing I will try is install the remote debugger. In the meantime, can someone tell me how to check if server trace is enabled (IIS 6)?

I need to upload this to my web server so I need to remove the local link .. I tried:
"eHNDB.mdf"
"~/eHNDB.mdf"
"~eHNDB.mdf"
"/eHNDB.mdf"
"eHNDB.mdf"
.. but i keep getting this error message when i try to open the page that accesses the DB. An attempt to attach an auto-named database for file eHNDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
1- what is the correct syntax to use in my web.comfig?
2- when online, i'm gonna be using sql server and not sql express .. what considerations / changes should i apply as well?

So I developed a web application in ASP.NET and SQL Server 2008. Part of the SQL code I implemented as a .NET assembly (instead of t-sql) because it is performing intense calculations that are better written in C#.
Now I am ready to deploy my application, but I am stuck looking for a hosting company that allows this. Scratch out Discount ASP (see this forum post). I tried emailing other hosting companies and I either get no reply or they say they will not support it.
Any recommendations? What's the big deal with having CLR enabled in SQL Server?

In building custom controls, I've seen two patterns for using the viewstate. One is to use properties to disguise the viewstate access as persistent data.
public bool AllowStuff
{
get
{
return (ViewState[constKeyAllowStuff] != null) ?
(bool)ViewState[constKeyAllowStuff] : false;
}
set { ViewState[constKeyAllowStuff] = value; }
}
The other is to use private member fields and to override the Load/SaveViewState methods on the control and handle it all explicitly:
protected override object SaveViewState()
{
object[] myViewState = new object[2];
myViewState[0] = base.SaveViewState();
myViewState[1] = _allowStuff;
return myViewState;
}
protected override void LoadViewState(object savedState)
{
object[] stateArray = (object[])savedState;
base.LoadViewState(stateArray[0]);
_allowStuff = (bool)stateArray[1];
}
(I cut out a lot of safety checking for clarity, so just ignore that.) Is there are particular advantage to one method over the other? I can't see how they'd differ much performance wise. Version 1 is lazy, so I guess you save a bit if you don't need that particular value during a pass. Version 1 is also more abstract, hides the details better. Version 2 is clearer about when the data is actually valid and ok to read or modify (between the load and save) because it more clearly works within the ASP.NET lifecycle. Version 2 does tend to require more boilerplate code though (a property, a backing private field, and viewstate handling in two places) as opposed to Version 1 which combines all that into one place.
