JavaScript onLoad event clashing
This week I had to debug some asp.net pages that has a weird behavior. They work well but each time a Js alert() raise, the hover menu are no more available (it is a classic asp:menu with dynamic hover for sub-menu).
The problem was simple: the current function attached to window.onload (which display the hover menu) was ripped by another one (which throw the alert).
Keep in mind that such line window.onload = alert('warning!'); remove the existing function attached to onload event.

Silverlight installation per machine/browser?
A question I had on top of my head:
When you install Silverlight, is it installed automatically on every browser available on your machine or is it per browser like Flash installation ? -

Maybe you already know about this, but as I still often see static method like GetColorFromHTML() in companies static class, it could be a good reminder. -

Expression Web and the annoying span lang
This has been annoying me for a while so now I found the trick let me share this :
I have Vista en-US, my keyboard is en-CA and Expression Web in english. Each time I write some text in an html page I get a <span lang="en-ca">...</span> inserted.Result: my pages are full of silly <span lang="en-ca">, and they are twice the size they should be!
Any "Auto insert language span" checkbox ??
No, that would be too easy!Here is what I found from a FrontPage MVP:
"To keep the <span lang="en-XX"> from being inserted into your html code.

Web Deployment Projects and Visual Studio 2008
I have been working a lot with Web Deployment Projects and even wrote articles on it, so I wanted to have a look at what comes with VS2008.
It appears that unlike what I thought, Web Deployment Projects will not be part of VS2008.According to the Web Development Tools Team's blog:
"We are planning to release and update of Web Deployment Projects for VS 2008 sometime shortly after VS2008 ships. At the moment we don't have anything available."
http://blogs.msdn.com/webdevtools/archive/2007/07/27/visual-studio-2008-beta-2-silverlight.aspxAccording to Scott Guthrie:
"They [Web Deployment Projects] will definitely work with VS 2008 at somepoint - although I suspect we need to release a new rev of them that registers on VS 2008."
http://weblogs.asp.net/scottgu/archive/2007/07/26/vs-2008-and-net-3-5-beta-2-released.aspx#3295301If you think Web Deployment Projects are important enough to be part of the final version of Visual Studio 2008 instead of being just an add-on you can vote for feature: "Include Web Deployment Projects in release of Visual Studio 2008" on Connect:

Cool tool: Windows Live Writer Beta 3
Live Writer beta 3 has shipped and... guess what, the bug with "Insert Picture" is finally fixed !!!!! That was long!
I was in touch with members of the dev team at Microsoft since both 2 previous versions, but it wasn't fix yet. So here we go, you can now insert pictures with accents in the path (like C:\users\Hélène\live.jpg), thanks for non-american users...Note that the installation delete my blogs configuration on my laptop :-( but it worked well on my desktop computer.

Microsoft CodeNames
Hey, just a quick link I found on Wikipedia :
http://en.wikipedia.org/wiki/List_of_Microsoft_codenamesMaybe you already heard about Atlas, Monad, Origami, Avalon, InfoCard or Kahuna... but did you know Springfield (Popfly) ? Sparkle (Blend) or Q (Windows Home Server) ?? Or maybe you don't care ;-) if not, you'll find the whole list of Microsoft Codenames there. While always on the cutting edge of technologies, working most of the time with codenames and beta products, this can be useful when a bit lost among all these names.

Delete Live OneCare backup folder in Vista
Problem: You reinstalled Live OneCare, or you start using v2 beta, and want to delete your old backup folder, but you can't. This is a permission problem, that maybe you can solve with cacls with command line:
cacls "<drive letter>:\<path>" /t /g administrators:F
Sample:
cacls "F:\Windows OneCare Backup\YourComputerName" /t /g administrators:F
Do NOT put a \ at the end of the path.You'll get a message "Are you sure(Y/N)?"

Which version of Silverlight is installed on your browser?
As you know Silverlight is currently available in 2 versions :
- v1.0 beta
- v1.1 alpha
First thing to know is the 1.1 alpha release contains the 1.0 beta bits, if you already installed 1.1 you do not need 1.0
Right, so how do you know which version of Silverlight is installed on your browser (Win)?
On IE if you go to Tools/Manage Add-ons, you see an AgControl pluggin, but no way to get the version there...
For IE/Win you can use the following code to detect the Silverlight version :
if ((navigator.userAgent.indexOf('Windows') != -1) &&
(navigator.appVersion.indexOf('MSIE') != -1) ) { try { var AgControl = new ActiveXObject("AgControl.AgControl"); agVersion = AgControl.settings.version; AgControl = null; } catch (e) { agVersion = -1; } } alert(agVersion);Version 0.90 is v1.0
Version 0.95 is v1.1Another way to check the version, more user friendly, look at the folder "C:\Program Files\Microsoft Silverlight", if you have 2 files only:

AJAX Control Toolkit now support theming!
This was amazing that all the AJAX Toolkit Controls was not designed to support Theme and Skins !! Most of them are extenders and should respect the idea of decoupling design from behaviours like regular ASP.NET 2.0 controls.
I voted for the issue on early february
http://www.codeplex.com/WorkItem/View.aspx?ProjectName=AtlasControlToolkit&WorkItemId=6838
and I'm glad to know that this has been processed!
David Anson did the work and checked in support for real ASP.NET Theme/Skin since build 19000 that shipped on march 01, 2007.Note that this release of the toolkit also brings good things such as localization support and two new controls (ListSearch and SlideShow), along with a number of fixes.
Why am I blogging this ?
The point here is when you find a bug or you would like to add a feature, juste ask for it!
For sure you can modify the source code, BUT I think it is far better to ask for the feature to the dev team, so it will be added to the library and you won't loose your changes on the next update.How to ask for a feature or report a bug ?
Feel free to add an item in the official issue tracker :
http://www.codeplex.com/AtlasControlToolkit/WorkItem/AdvancedList.aspx
This can be voted by everyone, checked and prioritized by the team and hopefully processed on a futur version.In the same idea
As you know AJAX Control Toolkit is a free library of controls that are built by both Microsoft and non-Microsoft developers. So you can develop your own control and bring your addition to the library (after validation by Microsoft team)!Note: In case you wonder I'm not (but maybe one day) part of the AJAX Control Toolkit team.
If you need more informations please go to the official project website:

Cheers to my reader from Iceland!
I've just installed MapVisitors on my blog, you can see a button on the left column here to show the map. Don't know yet how efficient is it, I installed ClustrMaps also to compare maps.
Anyway give it a try, it's free and it nicely uses Microsoft Virtual Earth API and pushpins.
As it is Virtual Earth you can navigate on the map, zoom and switch to aerial or hybrid views. Also the guys at MapVisitors are still working on it and plan to add new features like geographic grouping and use differently colored pushpins.
Usually I set Google Analytics for stats but no way to make it work on this Community Server blog... If you have a solution, thanks to share! -

Problem with Flash in IE7 ?
Maybe your are experiencing this like me: Your IE7 do not show flash content from some websites, even with Flash Player 9 installed on your system, and everything working fine with IE6 or Firefox.The fact is for some reasons IE7 corrupt Flash Plugin, in result flash detection on websites do not work. And if you try to click on one of the "upgrade Flash plugin" button the browser consider it is already installed.
Here is a solution:
- Close all open programs
- Run Adobe Flash Player Uninstaller
- Reinstall the Flash player
[From http://blog.deconcept.com/2006/12/08/corrupt-flash-player-install-after-ie-7-upgrade/]

ASP.NET 2.0 Themes and Custom Controls
Found an interesting one today on this old topic.
As you know you can skin your custom controls by adding a <%@ Register tag in your skin file.
This works great.But today I made a new company template and no way to make it work!
As soon as I add one of my custom control definition in the skin file I get an error :
"Type FooCompany.Agile.Web.UI.WebControls.XYZ is not defined".After 30min of headache I managed to make it work.
The problem was the Namespace containing my controls is FooCompany.Agile.Web.UI.WebControls and the Theme containing the skin is named FooCompany.
So I renamed my theme FooCompany_Design and everything is fine.Just after that I googled and (of course!) found that the problem was already solved 1 year before there :

IE Developer Toolbar Beta 3... What?
I've just noticed that a new beta version of the Internet Explorer Developer Toolbar is available! Not yet final but I like this Web Developer tool. No more toolbar menu in IE but a shortcut button instead, which open the bottom panel, the menu is inside this one now (but I think toolbar will be back again soon, or at least as an option).
Despite all the cool things in it I advise people NOT to install this version as it is far for stable and some features simply crash.
If you still want to try it, don't forget to uninstall previous beta versions.
What's new?
Still in beta but it comes with enhancements over previous versions, including:- Style Tracer: Right mouse click on a style value for an element and select Style Tracer to find the style rule that is effecting that value.
- CSS Selector Matches: View a report of all style rules set and how many times they are used on the current page.
- View Source: View the formatted and syntax colored source of the original page, currently rendered page, element or element with the styles that are effecting it.
What is it?
In case you don't know this IE extension, here is the official description: -

Paging tons of data in GridView
These days I was working on a web app dealing with large amount of data.
When it comes to display these data we use GridView and enable pagination in one click.
First thing to know is by default ASP.NET 2.0 GridView default paging is very poor in terms of performance because it first gets all data from db, and then trims the results to render the current page. And it does the same when you change to next page and the others!
Note that it was the same problem with ASP.NET 1.x DataGrid, then you had to implement custom paging to make things smart, that means getting only data that you need to display if you have multiple pages in your grid.With ASP.NET 2.0 you can very easily use custom paging, without writing a line of code behind!
Scott Mitchell wrote a very good article on how to implement this using the SQL Server 2005 new ROW_NUMBER() keyword and configuring your Object Data Source properly :Custom Paging in ASP.NET 2.0 with SQL Server 2005
Problem is my current app is using SQL Server 2000...
But chance is Greg Hamilton wrote a very nice tutorial to do the same in SQL Server 2000 using the SET ROWCOUNT command :A More Efficient Method for Paging Through Large Result Sets in SQL Server 2000
One more thing on the same idea of performance, many people, when creating primary key/foreign key relationships for joigning tables forget that while an index is automatically created on the primary key column, an index for a foreign key IS NOT automatically created, and must be created manually if needed. That could help if your paging's query use JOIN clauses.
And the final touch, now that we have Top efficient SQL work, we can move the GridView inside an ASP.NET AJAX UpdatePanel and let users navigate through data without PostBack! -
Best wishes : the geek way!
