protected virtual void OnComponentsCreating (System.Drawing.Design.ToolboxComponentsCreatingEventArgs args);

abstract member OnComponentsCreating : System.Drawing.Design.ToolboxComponentsCreatingEventArgs -> unit

Protected Overridable Sub OnComponentsCreating (args As ToolboxComponentsCreatingEventArgs)

Parameters

args: ToolboxComponentsCreatingEventArgs

A ToolboxComponentsCreatingEventArgs that provides data for the event.

Remarks

The OnComponentsCreating method raises the ComponentsCreating event. This method is called after a toolbox item is invoked to create components, just before the CreateComponentsCore method is called.

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnComponentsCreating method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding OnComponentsCreating(ToolboxComponentsCreatingEventArgs) in a derived class, be sure to call the base class' OnComponentsCreating(ToolboxComponentsCreatingEventArgs) method so that registered delegates receive the event.
