NavigateTo(String,Object) Method

Creates a NavigationHistoryItem with the specified parameters and sets it as the current item.
Syntax
'Declaration
 
Public Overloads Sub NavigateTo( _
   ByVal text As String, _
   ByVal tag As Object _
) 
public void NavigateTo( 
   string text,
   object tag
)

Parameters

text
The text to display when the item is shown in the recent history menu. Cannot be null or empty.
tag
An optional object to associate with the item.
Remarks

Similarly to how the navigation works in an explorer window in Vista, when navigating to a new item, a new path is started and the forward history is cleared.

Example
The following snippet handles an UltraTree's AfterSelect event to add the node to the navigation history so that the two elements can be in sync.

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.
