format numbers (culture depending)

custom number formatting

0	zero placeholder	{0:00.000}	1234.560
#	digit placeholder	{0:#.##}	1234.56
.	decimal point placeholder	{0:0.0}	1234.6
,	thousand separator	{0:0,0}	1,235
%	percentage	{0:0%}	123456%

there is also a group separator

 String.Format("{0:€#,##0.00;(€#,##0.00);None}", value);

the output will be "€128,00" for the value of 128, the same if the value is negative and None if the number is 0.

date formatting (culture depending)

custom date formatting

dd	Day	08
ddd	Short Day Name	Mon
dddd	Full Day Name	Monday
hh	2 digit hour	12
HH	2 digit hour (24 hour)	12
mm	2 digit minute	30
MM	Month	06
MMM	Short Month name	Jun
MMMM	Month name	June
ss	seconds	59
tt	AM/PM	PM
yy	2 digit year	70
yyyy	4 digit year	1970
:	seperator, e.g. {0:hh:mm:ss}	12:30:59
/	seperator, e.g. {0:dd/MM/yyyy}	08/06/1970

format strings

String.Format("click {0,10} to continue", "here"); (click           here to continue)
String.Format("click {0,-10} to continue", "here"); (click here           to continue)

This ScrewTurn wiki is really lightweight and easy to setup .. I like it.

I would really like to make this project and related sub projects (org.slm.securitymodule, org.slm.dbutils) opensource and available to the public and thought that the codeplex website would be a good option to host it? Many known opensource projects such as AjaxPro.Net and "AtlasControlToolkit" or as its called now ASP.NET AJAX Control Toolkit are hosted on that site.

I have been testing the drag and drop behavior and started with an example from garbins site. A great resource if you want to experiment with atlas behaviors.

I have created a little demo to test an issue I came up with related to a draggable item inside a scrollable div element.

When you scrolldown, the possition of the draggable is not correct anymore and this behavior only happens if the DragMode = Copy.
I think this is a small bug in the atlas framework .. and hopefully it will be fixed before releasing the next ctp.

Just a nice thing to share ;-)

The org.slm.softportal project is not a port of another portal system. I started from scratch and build it like I thought it would fit my needs.

Here is a summary of my requirements for the org.slm.softportal project:

• create a system of which the design is very easy to manage (template based with multiple skins).
• not focussed on blogging.
• rss feed support.
• a photo album / gallery.
• a media manager. (functionality to upload images to the server that can be used in news items or added to an album)
• possibility to add content and images that will be only visible to selected logged in persons or groups.
• a user manager.
• a link manager.
• a content manager.

The name of the project is org.slm.softportal and it is an asp.net web application written in c#.
