View.GetContextNodes method (XPathNavigator)

Office 2013 and later

Gets a reference to an XPathNodeIterator object for iterating over the returned XML nodes starting from the specified node.

Namespace:  Microsoft.Office.InfoPath
Assembly:  Microsoft.Office.InfoPath (in Microsoft.Office.InfoPath.dll)

Public MustOverride Function GetContextNodes ( _
	xmlNode As XPathNavigator _
) As XPathNodeIterator
Dim instance As View
Dim xmlNode As XPathNavigator
Dim returnValue As XPathNodeIterator

returnValue = instance.GetContextNodes(xmlNode)


Type: System.Xml.XPath.XPathNavigator

An object that specifies an XML node.

Return value

Type: System.Xml.XPath.XPathNodeIterator
An XPathNodeIterator that is populated with the nodes starting from the specified node.


The GetContextNodes method was called from an event handler for the Loading event.


The parameter passed to this method is a null reference (Nothing in Visual Basic).


The parameter passed to this method is not valid. For example, it is of the wrong type or format.

The XML nodes returned by the GetContextNodes method consists of a sequence of nodes that are mapped from the view, corresponding to the current XSL Transformation (XSLT) node, starting at the specified node and walking up through the view ancestors to the BODY tag.

If specified nodes are bound to more than one control in the view, you must use the GetContextNodes method instead which allows you to specify the ViewContext identifier of the control that is bound to the nodes you want to iterate over.


The GetContextNodes method will not return nodes based on the current selection if used in the event handler for the Clicked event of a button in the view, because the focus is lost from the control that is intended to be in context. To avoid this behavior, use GetContextNodes from a custom task pane, menu, or toolbar.

This member can be accessed only by forms running in the same domain as the currently open form, or by forms that have been granted cross-domain permissions.

This type or member can be accessed only from code running in forms opened in Microsoft InfoPath Filler.

In the following example, the SelectNodes method is used to select the nodes in the first row of a Repeating Table control bound to group2. The GetContextNodes method is then used to return a collection of context nodes based on the current selection and the specified node. Finally, the code then loops through the collection of context nodes and displays the name, inner XML, and value of each node.

' Create XPathNavigator and specify XPath for nodes.
Dim repeatingTableRow1 As XPathNavigator  = _
   CreateNavigator().SelectSingleNode( _
   "/my:myFields/my:group1/my:group2[1]", NamespaceManager)

' Select nodes in specified XPathNavigator.

' Get context nodes in selection.
Dim contextNodes As XPathNodeIterator = _

' Loop through collection and display information.
Dim contextNode As XPathNavigator
For Each contextNode In contextNodes
