Package.ToolboxInitialized Event

Event generated whenever Visual Studio initializes its Toolbox.

Namespace:  Microsoft.VisualStudio.Shell
Assembly:  Microsoft.VisualStudio.Shell.10.0 (in Microsoft.VisualStudio.Shell.10.0.dll)

protected event EventHandler ToolboxInitialized

The Visual Studio IDE generates a ToolboxInitialized event whenever one or more of the following situations occur:

  1. A user manually resets the Toolbox by right-clicking on one of the Toolbox categories and selection Reset Toolbox.

  2. A new VSPackage providing Toolbox items is registered.

  3. A VSPackage programmatically generates a ToolboxInitialized event through the Visual Studio SDK by a VSPackage calling ResetDefaults with PKGRF_TOOLBOXITEMS.

                IVsUIShell uiShell = (IVsUIShell)GetService(typeof(SVsUIShell));
                IVsPackage pkg = GetService(typeof(Package)) as IVsPackage;
