ToolboxItemContainer is a simple class that encapsulates a ToolboxItem for efficiency. By having a single class that is always loaded, you can defer the loading of the ToolboxItem until it is needed. Because new classes can be derived from ToolboxItem, you could load a ToolboxItem that could, in turn, load an assembly that is not already in memory. For a large collection of ToolboxItem objects, this could cause a large number of assemblies to be loaded, which decreases performance. Instead, the toolbox service deals only with ToolboxItemContainer objects and retrieves their contained ToolboxItem only when necessary.
The ToolboxItemContainer is designed to hold any cached data from the ToolboxItem. The default implementation only holds the filter of the ToolboxItem, but deriving classes may choose to cache the name, image, and other information. ToolboxItemContainer objects support two forms of serialization: they can be serialized through standard runtime serialization, and they can also load and save themselves from a System.Windows.Forms.IDataObject. The former provides a very easy way to save ToolboxItemContainer objects to a persistent storage. The latter provides a way to integrate ToolboxItemContainer objects with mixed data storage formats.
Initializes a new instance of the ToolboxItemContainer class from a serialization stream.
Gets a value indicating whether the underlying toolbox item has been deserialized.
Determines whether two ToolboxItemContainer instances are equal.
Returns the hash code for this instance.
Saves the serialization state for the object.
Gets the Type of the current instance.(Inherited from Object)
Creates a shallow copy of the current Object.(Inherited from Object)
Returns a string that represents the current object.(Inherited from Object)
Merges the container's filter with the filter from the given item.
