Just add this to the url in the browser address bar:

?SortField=Modified&SortDir=Asc

To reduce postbacks and database calls, a copy of the current object(s) can be pushed down to the client in JSON format. Say a webpart renders information about a person, another webpart shows related information which is retrieved dynamically (like web services). Instead of getting the current person from the database in the second webpart again, we can reuse the same person object from the first webpart. To do so we must provide a DataContract for the Person class:

PeopleEditor is a nice webcontrol for picking people. To add it to your webpart or page is easy: But there is more we can do with pickers in Sharepoin. We can define our own pickers. Jeremy Luerkens gives one such example and a code sample (!). Another example can be found in Sharepoint as a Development Platform (p. 661), even though it misses the important class BookQueryControl. Just to start I made a book picker (I simplified and changed the idea provided in the book). Here is the working result, for simplicity the whole code is in one file:

A tip for all who want to administer AD with powershell: Idera Powershell scripts. Just sign up and get the free scripts for AD, SQL, Exchange and Sharepoint. I personally prefer to user modules, so I change the file extension from ps1 to psm1 and then I can use import functions as modules. Here is a simple example for creating for domain users:

import-module .\New-IADUser1.psm1
function Add-User($name) {
    New-IADUser -Name $name `
         -sAMAccountname $name `
         -ParentContainer 'CN=Users, DC=contoso, DC=com' `
         -Password 'SvenskaAkademien1786' `
         -EnableAccount -PasswordNeverExpires
}
Add-User "user01"
Add-User "user02"
Add-User "user03"
Add-User "user04"

update 2012-03-15: nice script from Ryan

Ryan Dennis has created a very handy script for creating random users. In PowerShell v3.0 there is a cmdlet for creating users: New-ADUser. So the function above can be rewritten like that:

There is a very handy JSON lib for serializing javascript objects. It is hosted on github under douglas crockford. Download json2.js and serialize with JSON.stringify function: EDIT: There is actually this function in core javascript. It exists since javascript 1.7 and ecmascript 5. So you don’t have to add anything to get this functionality:

var t = { name: "dev", city: "new york" };
JSON.stringify(t);
```There are actually built-in goodies for serializing javascript objects in [ASP.NET](http://msdn.microsoft.com/en-us/library/bb310857.aspx): Sys.Serialization.JavaScriptSerializer.serialize

var t = { name: “dev”, city: “new york” }; Sys.Serialization.JavaScriptSerializer.serialize(t);

play! framework Inspired by ComputerSweden I played with Play! Here I’ll just put some commands to create and deploy a Play! web application, actually more for myself, to remember the steps to get started quickly. It would be great of course, if someone else finds it useful. The code for this little simple app. Play! is a java based framework for web applications. It reminds the rails framework and provides many useful features as CRUD, REST and more out of the box. In this post I create an download play and unpack in your home directory add to your path and save this in login script (.bashrc)

See a great post in “Learning Sharepoint” with an example how to get a picture of user with Client Object Model and javascript.

To get the distinguished name for a user, it isn’t enough to get an SPUser object. The distinguished name is the unique string for identifying a user in Active Directory (eg. CN=BeforeDAfter,OU=Test,DC=North America,DC=Fabrikam,DC=COM) Even using UserProfile object is not that clear. The distinguished name can be found in a property which can be retrieved with brackets: up[PropertyConstants.DistinguishedName]

public static string GetDistinguishedName(string login)
{
   var dn = "";
   UserProfile up;
   using (var site = new SPSite("http://dev"))
   {
      var serviceContext = SPServiceContext.GetContext(site);
      var upm = new UserProfileManager(serviceContext);
      var exists = upm.UserExists(login);
      if (!exists)
         upm.CreateUserProfile(login);
      if (exists)
      {
         up = upm.GetUserProfile(login);
         dn = up\[PropertyConstants.DistinguishedName\].Value.ToString();
      }
   }
   return dn;
}
```The code is simplified and doesn't contain any error handling. And a better handling of upm.UserExists must be implemented: If upm.CreateUserProfile(login) runs, it doesn't make it so quickly and the next step won't run (upm.GetUserProfile). If you are not working in SP Context, you can see the distinguished name for a user in Powershell:

import-module activedirectory $u = get-aduser administrator $u.DistinguishedName

See Richards Bradshaw’s page with explanations and examples of css3 transform and transitions. His code is also available for forking on Github.

If you have used SPUtility.TimeDeltaAsString you must know how useful it is. There is also the jQuery plugin that can perform counting of time deltas and (!) translate it. jQuery timeago is available for many languages, Swedish among others:

// Swedish
jQuery.timeago.settings.strings = {
  prefixAgo: "för",
  prefixFromNow: "om",
  suffixAgo: "sedan",
  suffixFromNow: "",
  seconds: "mindre än en minut",
  minute: "ungefär en minut",
  minutes: "%d minuter",
  hour: "ungefär en timme",
  hours: "ungefär %d timmar",
  day: "en dag",
  days: "%d dagar",
  month: "ungefär en månad",
  months: "%d månader",
  year: "ungefär ett år",
  years: "%d år"
};
```The code is hosted on [Github](https://github.com/rmm5t/jquery-timeago). In order the time deltas to be localized in SharePoint a ScriptLink has to be used:

<SharePoint:ScriptLink ID=“timeagoLanguage” runat=“server” Language=“javascript” Name=“jquery.timeago.lang.js” Localizable=“True” LoadAfterUI=“True” OnDemand=“False” ></SharePoint:ScriptLink>
