C# Extension to Delete selected SharePoint List Items

It is a common requirement to delete set of SharePoint list items from a list. In most case you might want to do that quickly as well. Here is a extension method that I wrote to accomplish that.

 public static void DeleteItemsCollection(this SPList list, SPWeb web, SPListItemCollection listitemCollection)
StringBuilder deletebuilder = DeleteBatchCommand(list, listitemCollection);


StringBuilder DeleteBatchCommand(SPList spList, SPListItemCollection listitemCollection)
StringBuilder deletebuilder = new StringBuilder();
deletebuilder.Append(“<?xml version=\”1.0\” encoding=\”UTF-8\”?><Batch>”);
string command = “<Method><SetList Scope=\”Request\”>” + spList.ID +
“</SetList><SetVar Name=\”ID\”>{0}</SetVar><SetVar Name=\”Cmd\”>Delete</SetVar></Method>”;

foreach (SPListItem item in listitemCollection)
deletebuilder.Append(string.Format(command, item.ID.ToString()));
return deletebuilder;

The method “DeleteItemsCollection” can be called up on any list together with SPWeb and the collection list items that you want to get rid of the list. You can simply execute the method as follows.

myList.DeleteItemsCollection(web, itemsToDelete);


Add Quick Launch Navigation Entries together with Localization Text using Powershell

Its a time where most SharePoint developers look to do everything possible with Powershell rather than writing thousands of C# code. One common simple such requirement is to add Navigation Entries to Quick Launch. This is specially very useful when you work with a site where publishing features are not available so that you can not use the GUI to add navigation entries either.

Here is the code,

    $webURL =  “http://mySPSiteURL/&#8221;
$enTitle = “Chaminda’s Blog ”
$frTitle = “Blog de Chaminda”
$urlLink =”https://chamindasomathilaka.wordpress.com&#8221;

$webs = Get-SPWeb -Identity $webURL -ea Stop

$navigation= $webs.Navigation.QuickLaunch

$culture = New-Object System.Globalization.Cultureinfo(“fr-FR”)
$cultureFrCA = New-Object System.Globalization.Cultureinfo(“fr-CA”)

$newnode = New-Object Microsoft.SharePoint.Navigation.SPNavigationNode($enTitle, $urlLink, $true)

$addedNode = $navigation.AddAsLast($newnode)

$addedNode.TitleResource.SetValueForUICulture($culture, $frTitle)
$addedNode.TitleResource.SetValueForUICulture($cultureFrCA, $frTitle)



That is to add a Quick Launch navigation entry directing my blog with both English and French translation (this is in case you have both English and French languages are available on your site).

Same code can be used to add Navigation entry to Top Navigation Area as well. you just need to initialize $navigation variable with correct navigation.

   $navigation= $webs.Navigation.TopNavigationBar

Changing SharePoint database from SQLExpress Edition to Default SQL Server Instance for Standalone Installation

I’m a big lover of using base machine for SharePoint development work instead of using different VMs. I love that approach,

  1. SharePoint runs much faster as it has more comfortable memory and processing power usage
  2. Visual Studio runs much faster
  3. I have access to all other tools such as MS office etc
  4. Last but no least I will not have to transfer my tools from every time I put up a new VM

I have been running SharePoint 2010 on my desktop for more than a year now, while working few different SharePoint and non-SharePoint projects.  I used this very nice article on how to setup SharePoint on Windows 7 few times now to set my dev env without noticing the SharePoint installation automatically install a SQL Server Express edition instance and make use that as the SharePoint’s database.  This was only noticed when I want to get rid of any redundant processes so that I can free up some of the processing power on the machine. For other .net related development I used to have an full SQL Server installation and addition to that my machine is running an SQL Express Edition instance for SharePoint. So I wanted to get rid of this express edition and make use of full SQL Server edition’s default instance for SharePoint as well.  So started in a hard way, uninstall my SQL express edition instance and ran the SharePoint Configuration Wizard, thinking it will notice the loss of SharePoint Configuration database and ask me to create new farm. But it didn’t go that way, instead wizard keep crashing with the message saying unable connect to SQL Server.

However finally I was able to get it to configure new farm by following steps.

  1. Got the env to disconnect from the farm by setting the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\14.0\WSS\ServerType to CLEAN_INSTALL and running the SharePoint Configuration Wizard (refer this)
  2. Then set the Server role to be Application (instead SingleServer) by setting registry entry HKLM/Software/Microsoft/Shared Tools/Web Server Extensions/12.0/WSS -> ServerRole key from ‘SingleServer’ to ‘Application’  (refer this)
  3. Then run the ShaerPoint Configration Wizard to configure new farm by providing default sql server instace (or any other SQL Server database instance) as the database
