The Properties window is used to display properties for objects selected in the two main types of windows available in the Visual Studio integrated development environment (IDE). These two types of windows are:

Tool windows such as Solution Explorer, Class View, and Object browser
Document windows containing such editors and designers as the forms designer, XML editor, and HTML editor

Using the Properties Window

The Properties window displays the properties of single or multiple selected items. If multiple items are selected, the intersection of all properties for all selected objects is displayed.

Events related to a selected object within a form design window or HTML editor using COM+ metadata are displayed in the Properties window. For example, you can select a button and display its associated events, such as an OnClick event, which can be linked to that button.

Events displayed in the Properties window are primarily used with objects that are bound to code. If you are editing a file format that does not have anything to do with code, you are not going to have any events. Events are only displayed in the Properties window when there is a binding between running code and certain events associated with specific objects. An example of this would be code behind a selected object that executes when that object is activated.

The following table lists the primary interfaces used by the Properties window.

Interface Name	Description
ICategorizeProperties	Provides a list of categories to the Properties window and maps each property to a category.
IDispatch Interface	Exposes an object's methods and properties to programming tools and other applications that support automation.
IProvidePropertyBuilder	Provides ellipsis (...) buttons called builders that open modal dialog windows implemented by the object itself. Used when a value is not easily typed by the user in a text field. For example, it might be used to open a color picker that determines the RGB value for you.
ISelectionContainer	Provides access to objects used to update information displayed in the Properties window. ISelectionContainer is implemented by VSPackages for each window that contains selectable objects with related properties to be displayed.
ITypeInfo	Provides information about the type of an object such as methods of an interface and fields of a structure.
IVsMonitorSelection	Enables VSPackages to receive notification of selection events and to retrieve information about the current project hierarchy, item, element value, and command UI context.
IVsMultiItemSelect	Provides the environment with access to multiple selections.
IVsPerPropertyBrowsing	Used to provide localized names on some properties displayed in the Properties window.
IVsSelectionEvents	Notifies registered VSPackages of changes to the current selection, element value, or command UI context.
IVsTrackSelectionEx	Notifies the environment of a change in the current selection and provides access to hierarchy and item information relating to the new selection.
