PersistedInfo Property

Returns or sets additional information to persist when the MdiTab object is persisted.
Syntax
'Declaration
 
Public Property PersistedInfo As Object
public object PersistedInfo {get; set;}
Remarks

When the SaveAsXml(Stream) or the SaveAsBinary(Stream) method is invoked to save the layout and properties of the tabs and tabgroups, the StoreTab is invoked for each tab managed by the UltraTabbedMdiManager. It is recommended that you set this property in that event to a serializable object (e.g. string) that contains enough information to create the appropriate form when deserialized. When the UltraTabbedMdiManager.LoadFromXml or UltraTabbedMdiManager.LoadFromBinary method is invoked, the RestoreTab event is invoked. The event provides the deserialized MdiTab so you may access the serialized PersistedInfo and create the appropriate Form.

Note: This property is not used by the MdiTab but exists to aid in deserialization. If set, the value must be serializable (see System.Type.IsSerializable).

Example
The following example demonstrates how to use the StoreTab event to initialize the PersistedInfo of an MdiTab object.

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.
