CurrentItem Property (NavigationToolbar)

Gets the item that is currently navigated to, or null if no navigation has occurred.

Syntax

Visual Basic

'Declaration
 
Public ReadOnly Property CurrentItem As NavigationHistoryItem

C#

public NavigationHistoryItem CurrentItem {get;}

Example

The following code snippet demonstrates how to iterate through the BackHistory and Forward history in order to save this information to an XML file.
Note that the Tag property is not serialized here because it is of type object, so individual serialization mechanisms should be used based on the data type in your application.

Visual Basic

Imports System.Xml
Imports Infragistics.Win.UltraWinToolbars

Private Sub btnSaveHistory_Click(ByVal sender As Object, ByVal e As EventArgs)
	Dim writer As XmlTextWriter = Nothing

	Try
		writer = New XmlTextWriter("History.xml", Nothing)
		writer.Formatting = Formatting.Indented
		writer.Namespaces = False
		writer.WriteStartDocument()
		writer.WriteStartElement("History")

		' Serialize the back history
		If Me.UltraToolbarsManager1.NavigationToolbar.BackHistoryCount > 0 Then
			writer.WriteStartElement("BackHistory")
			Dim backHistoryItem As NavigationHistoryItem
			For Each backHistoryItem In Me.UltraToolbarsManager1.NavigationToolbar.BackHistory
				writer.WriteStartElement("Item")
				writer.WriteString(backHistoryItem.Text)
				writer.WriteEndElement()
			Next
			writer.WriteEndElement()
		End If

		' Serialize the current item
		Dim currentItem As NavigationHistoryItem = Me.UltraToolbarsManager1.NavigationToolbar.CurrentItem
		If Not currentItem Is Nothing Then
			writer.WriteStartElement("CurrentItem")
			writer.WriteString(currentItem.Text)
			writer.WriteEndElement()
		End If

		' Serialize the forward history
		If Me.UltraToolbarsManager1.NavigationToolbar.ForwardHistoryCount > 0 Then
			writer.WriteStartElement("ForwardHistory")
			Dim forwardHistoryItem As NavigationHistoryItem
			For Each forwardHistoryItem In Me.UltraToolbarsManager1.NavigationToolbar.ForwardHistory
				writer.WriteStartElement("Item")
				writer.WriteString(forwardHistoryItem.Text)
				writer.WriteEndElement()
			Next
			writer.WriteEndElement()
		End If

		writer.WriteEndElement()
		writer.WriteEndDocument()
		writer.Flush()
	Catch ex As Exception
		MessageBox.Show("Could not serialize history\n\n" + ex.Message)
	Finally
		If Not writer Is Nothing Then
			writer.Close()
		End If
	End Try
End Sub
