Finding out the SharePoint list ID (ListTemplateId)

SharePoint 2007 offers an enhanced ability to catch certain user events such as ItemDeleting (before the fact) and ItemDeleted (after the fact). The API targets specific lists identified by list IDs. Example:

List template type	Template ID
Custom List	100
Document Library	101
Survey	102
Links List	103
Announcement List	104
Contacts List	105
Events List	106
Task List	107
Discussion Board	108
Picture Library	109

You can find out the list ID of any other list as follows:

• Go to your 12 hives FEATURES folder C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\FEATURES
• Find the folder for the list you are interested in and open it.
• Open the ListTemplates folder
• Open the XML file and read the value of the Type attribute.
• This information can also be found in the ONET.XML file in the appropriate site template directory under C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\SiteTemplates
