Introduction:
Location based metadata defaults manages the default values of metadata fields
based on location and applies them so that they are available when the user
edits a document. SharePoint 2010 allows setting the default metadata values to
the document library, folders and sub folders, so that users do not have to
enter the metadata values when they upload the documents in the document
library. Please refer
http://msdn.microsoft.com/en-us/library/ee557925.aspx for
location-based metadata defaults on columns that support setting defaults, in a
hierarchy of folders. In this article we will be seeing how to get and set
metadata default values using SharePoint object model.
Description:
I have a document library "Shared Documents" which has folders and sub folders
as shown in the following figure.
![MtDataShare1.gif]()
I have created single line of text column in Shared Documents which will be used
for setting metadata defaults for the folder and sub folders.
Shared Documents has the following columns
![MtDataShare2.gif]()
For the Finance folder I have set the metadata default value as Finance.

MetadataDefaults Class:
MetadataDefaults class is used to provide a way to set and get default values
for fields based on where the document is added.
Namespace: Microsoft.Office.DocumentManagement
Assembly: Microsoft.Office.DocumentManagement (in
Microsoft.Office.DocumentManagement.dll)
MetadataDefaults Constructor (SPList):
This is used to initialize a new instance of a object.
In this article we will be seeing the following
- Gets the default value for a specified
folder and field.
- Gets the default value for a specified
field and folder.
- Removes all of the default values set on
the document library.
- Removes all of the defaults set at a
specified location.
- Removes all of the default values that are
set at a specified location.
- Removes the default value of a
SPField
object at a specified SPFolder object.
- Removes the default value of a field from
an SPFolder
object.
- Sets a default for a field at a location.
- Sets a default value for a default field
to apply to documents at a specified location.
Create a Console Application:
- Open Visual Studio 2010,
- Go to File => New => Project.
- Select Console Application template from
the installed templates.
- Enter the name for the project and click
on Ok.
- Add the following reference
-
Microsoft.SharePoint
- Microsoft.Office.DocumentManagement
- Add the following Namespaces
-
Using Microsoft.SharePoint;
-
Using Microsoft.Office.DocumentManagement;
Gets the default value for a specified
folder and field:
