ComponentDesigner.InitializeExistingComponent Method

Reinitializes an existing component.

Namespace: System.ComponentModel.Design
Assembly: System.Design (in

public virtual void InitializeExistingComponent (
	IDictionary defaultValues
public void InitializeExistingComponent (
	IDictionary defaultValues
public function InitializeExistingComponent (
	defaultValues : IDictionary
Not applicable.



A name/value dictionary of default values to apply to properties. May be a null reference (Nothing in Visual Basic) if no default values are specified.

The InitializeExistingComponent method is called when an existing component is being reinitialized. For example, this may occur after the user drags a component to another container.

You may use the defaultValues dictionary to apply recommended defaults to properties; however, you should not modify component properties aside from those stored in the dictionary, because this existing component may already have properties set on it.

The default implementation of this method does nothing.
