Properties

	Name	Description
	AppDomainCreatorType	Gets or sets the type of the IToolboxAppDomainControl implementation.
	FileFilter	Gets or sets the file filter for the browse dialog.
	HelperObjectType	Gets or sets the type of the helper object that will be passed to your IToolboxItemDiscovery implementation's constructor.
	HideAssemblyName	Gets or sets whether the current tab is to hide the assembly name column in the Choose Toolbox Items dialog. If true, the assembly name column is hidden; if false (default), the assembly name column is displayed.
	HideCulture	Gets or sets whether the current tab is to hide the language information in the Choose Toolbox Items dialog. If true, the language information is hidden; if false (default), the language information is displayed.
	HideDirectory	Gets or sets whether the current tab is to hide the directory column in the Choose Toolbox Items dialog. If true, the directory column is hidden; if false (default), the directory column is displayed.
	HideNamespace	Gets or sets whether the current tab is to hide the namespace column in the Choose Toolbox Items dialog. If true, the namespace column is hidden; if false (default) the namespace column is displayed.
	HideVersion	Gets or sets whether the current tab is to hide the version in the Choose Toolbox Items dialog. If true, the version is hidden; if false (default), the version is displayed.
	ItemCreatorType	Gets the type of the IToolboxItemCreator implementation.
	ItemDiscoveryType	Gets the type of the IToolboxItemDiscovery implementation.
	ItemPropertyIdsAndNames	Gets a collection of extra columns (as identifier-Display-Name pairs) to display in the dialog.
	PageOrder	Gets or sets the sort order of the page. If zero, the page is left unsorted and will appear after all pages with nonzero order values. Pages with equal order values are sorted alphabetically by name.
	PlatformsToEnumerate	Gets or sets a collection of platform identifiers indicating the platforms that should be enumerated to populate the list in this item type's Choose Toolbox Items page.
	TypeId	Gets the identity of this instance of the attribute. (Overrides RegistrationAttribute.TypeId.)
	VisibilityUIContexts	Gets or sets a list of UIContexts that controls the visibility of the tab. The tab is hidden if none of the UI contexts are set. Only non-dynamic UI contexts are supported (for example, OsWindows8OrHigherContext). Use of dynamic contexts like NoSolutionContext is not supported and results in non-deterministic behaviors.
