ToolboxComponentsCreatingEventHandler Delegate

Represents the method that handles the ComponentsCreating event.

Namespace: System.Drawing.Design
Assembly: System.Drawing (in system.drawing.dll)

public delegate void ToolboxComponentsCreatingEventHandler (
	Object sender,
	ToolboxComponentsCreatingEventArgs e
)
/** @delegate */
public delegate void ToolboxComponentsCreatingEventHandler (
	Object sender, 
	ToolboxComponentsCreatingEventArgs e
)
Not applicable.

Parameters

sender

The source of the event.

e

A ToolboxComponentsCreatingEventArgs that provides data for the event.

When you create a ToolboxComponentsCreatingEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events and Delegates.

The following example code provides a method that attaches an event handler for the ComponentsCreating event of a ToolboxItem, and a ToolboxComponentsCreatingEventHandler event handler method that writes the name of the type of the component that is to receive the new component or components to the Console when the event handler is raised by a ComponentsCreating event.

public void LinkToolboxComponentsCreatingEvent(ToolboxItem item)
{
    item.ComponentsCreating += new ToolboxComponentsCreatingEventHandler(this.OnComponentsCreating);
}

private void OnComponentsCreating(object sender, ToolboxComponentsCreatingEventArgs e)
{
    // Displays ComponentsCreating event information on the Console.
    Console.WriteLine("Name of the class of the root component of " +
    "the designer host receiving new components: " +
    e.DesignerHost.RootComponentClassName);
}
