ControlDesigner.RegisterClone Method

Registers internal data in a cloned control.

Namespace:  System.Web.UI.Design
Assembly:  System.Design (in System.Design.dll)

public void RegisterClone(
	Object original,
	Object clone
)

Parameters

original
Type: System.Object

The control associated with the control designer.

clone
Type: System.Object

The cloned copy of the associated control.

ExceptionCondition
ArgumentNullException

original is null.

-or-

clone is null.

Whenever an item is cloned, there might be some internal data structures, such as meta: attributes, that should be included in the cloned control by the control designer. A page developer might add meta: attributes to the markup of a control and there is no way, nor is there a reason, for the control to distinguish what those tags might be. Therefore, if your control designer provides a way to edit complex properties or formats before applying changes to a page, you would create a clone of the control, pass both the original control and the clone to this RegisterClone method, and then, when the changes are persisted to the tag, all meta: attributes are also persisted.
