Properties

  Name Description
Public property AppDomainCreatorType Gets or sets the type of the IToolboxAppDomainControl implementation.
Public property FileFilter Gets or sets the file filter for the browse dialog.
Public property HelperObjectType Gets or sets the type of the helper object that will be passed to your IToolboxItemDiscovery implementation's constructor.
Public property 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.
Public property 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.
Public property 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.
Public property 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.
Public property 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.
Public property ItemCreatorType Gets the type of the IToolboxItemCreator implementation.
Public property ItemDiscoveryType Gets the type of the IToolboxItemDiscovery implementation.
Public property ItemPropertyIdsAndNames Gets a collection of extra columns (as identifier-Display-Name pairs) to display in the dialog.
Public property 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.
Public property 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.
Public property TypeId Gets the identity of this instance of the attribute. (Overrides RegistrationAttribute.TypeId.)
Public property 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.
