Sorting Fields in a View

Outlook items can be sorted by adding one or more Outlook item properties to the OrderFields collection of any of the following objects:

Outlook items in a CalendarView or TimelineView object are displayed in chronological order, depending on the values of the Outlook item properties specified for the StartField and EndField properties of the view.

The OrderFields collection for those views can be retrieved by calling the SortFields property of the appropriate view object. The Add method of the OrderFields collection is used to create an OrderField object that represents the Outlook item property to be sorted.

You can add either built-in or custom Outlook item properties to the OrderFields collection. The order in which the properties are included in the OrderFields collection determines the order in which the properties are sorted, while the IsDescending property of the OrderField object which represents an Outlook item property determines whether the values of that property are sorted in ascending or descending order.

The following guidelines should be used when specifying built-in Outlook item properties:

  • Built-in properties can be specified either by property name (for example, "Subject") or by namespace (for example, "http://schemas.microsoft.com/mapi/proptag/0x0037001E").

  • Property names are not case-sensitive and cannot include spaces.

  • Namespace identifiers are case-sensitive, must follow URL encoding rules, and cannot be enclosed in square brackets ([]).

The following guidelines should be used when specifying custom properties:

  • The custom property must be available in the UserDefinedProperties collection for the parent Folder object.

  • Custom properties should be specified by property name (for example, "[Shoe Size]").

  • Custom property names are not case-sensitive, can include spaces, and should be enclosed in square brackets ([]) if they contain spaces.

For more information about property identifiers, see Properties Overview.
