public class AnnTextRollupObject : AnnNoteObject, IAnnFont, IAnnHeader, IAnnObject, IAnnRectangle, IAnnText

'Declaration
 
Public Class AnnTextRollupObject 
   Inherits AnnNoteObject
   Implements IAnnFont, IAnnHeader, IAnnObject, IAnnRectangle, IAnnText

'Usage
 
Dim instance As AnnTextRollupObject

public ref class AnnTextRollupObject : public AnnNoteObject, IAnnFont, IAnnHeader, IAnnObject, IAnnRectangle, IAnnText

The text rollup annotation object extends AnnNoteObject by adding an IsExpanded property. When this property is set to false, the text rollup object looks and behaves like a normal note. When IsExpanded is set to false, the text rollup object will shrink to show only one line of text. This saves space on the container surface. For more information, refer to Using Text in WPF Annotation Objects. For more information about the text rollup annotation object refer to WPF AnnTextRollupObject. For more information about the automated text rollup annotation object, refer to WPF Annotation Objects - Automated Features.
