Properties Window Buttons

Depending on the development language and the product type, certain buttons are displayed by default on the toolbar for the Properties window. In all cases, the Categorized, Alphabetized, Properties, and Property Pages buttons are displayed. In Visual C# and Visual Basic, the Events button is also displayed. In certain Visual C++ projects, the VC++ Messages and the VC Overrides buttons are displayed. Additional buttons may be displayed for other project types. For more information about buttons in the Properties window, see Properties Window.

Implementation of Properties Window Buttons

When you click the Categorized button, Visual Studio calls the ICategorizeProperties interface on the object that has focus to sort its properties by category. ICategorizeProperties is implemented on the IDispatch object that is presented to the Properties window.

There are 11 predefined property categories, which have negative values. You can define custom categories, but we recommend that you assign them positive values to distinguish them from the predefined categories.

The MapPropertyToCategory method returns the appropriate property category value for the specified property. The GetCategoryName method returns a string that contains the category name. You only have to provide support for custom category values because Visual Studio knows the standard property category values.

When you click the Alphabetized button, the properties are displayed in alphabetical order by name. The names are retrieved by IDispatch according to a localized sorting algorithm.

When the Properties window is open, the Properties button is automatically shown as selected. In other parts of the environment, the same button is displayed, and you can click it to show the Properties window.

The Property Pages button is unavailable if ISpecifyPropertyPages is not implemented for the selected object. Property pages display configuration-dependent properties that are typically associated with solutions and projects, but they can be also be associated with project items (for example, in Visual C++).

Note

You cannot add toolbar buttons to the Properties window by using unmanaged code. To add a toolbar button, you must create a managed object that derives from PropertyTab.
