As i mentioned in my last post it’d be useful to be able to sort the content types in a document library’s new button. This builds on the examples in the previous post but it can be run on it’s own.

This script will attempt to set a default content type, if one is specified, but if it isn’t or the one listed can’t be found it’ll default to alphabetical.

Function Sort-ContentTypesInNewButton{

[CmdletBinding()]
Param ( [parameter(Mandatory=$false)][string] $DefaultContentTypeName,
[parameter(Mandatory=$true,ValueFromPipeline=$true)][Microsoft.SharePoint.SPList] $SPList)
BEGIN {
Write-Verbose "Begining Sort-ContentTypesInNewButton"
}
PROCESS { 

$rootFolder = $SPList.RootFolder

#Get content types fromt the button
$contentTypesInPlace = New-Object 'System.Collections.Generic.List[Microsoft.SharePoint.SPContentType]'
$contentTypesInPlace = $rootFolder.UniqueContentTypeOrder

#Has a default content type name been specified?
if ($DefaultContentTypeName)
{
$contentType = $contentTypesInPlace | where { $_.Name -eq $DefaultContentTypeName }
if ($contentType -ne $null)
{
#Add the default content type
$sortedListOfContentTypes = New-Object 'System.Collections.Generic.List[Microsoft.SharePoint.SPContentType]'
$sortedListOfContentTypes += $SPList.ContentTypes[$DefaultContentTypeName]

#Remove the default content type from the list
$contentTypesInPlace = $contentTypesInPlace | where {$_.Name -ne $DefaultContentTypeName}
}
else
{
Write-Error "$DefaultContentTypeName was not found in the list, sorting by Name alone"
}
}
else
{
Write-Verbose "No default content type specified"
}

#sort the remaining content types and add the sorted list
foreach ($contentType in $($contentTypesInPlace | Sort-Object -Property Name ))
{
#Add the content types 
$sortedListOfContentTypes = [Microsoft.SharePoint.SPContentType[]] $sortedListOfContentTypes + $contentType
}

$rootFolder.UniqueContentTypeOrder = [Microsoft.SharePoint.SPContentType[]] $sortedListOfContentTypes

#Update the root folder
$rootFolder.Update()
Write-Verbose "ContentType(s) sorted and added to the new button in list $($SPList.Name)"

}
End{
Write-Verbose "Ending Sort-ContentTypesInNewButton"
}

}
