)
'Usage
Dim instance As ContextNode
Dim subNodeToDelete As ContextNode

ContextNode subNodeToDelete
)
public:
void DeleteSubNode(
ContextNode^ subNodeToDelete
)
public function DeleteSubNode(
subNodeToDelete : ContextNode
)
Parameters
subNodeToDelete
Type: Microsoft.Ink.ContextNodeThe ContextNode to delete.

Examples
This example puts all the lines into their own paragraphs. It uses the lines from an InkAnalyzer, theInkAnalyzer; creates a new paragraph subnode for each of them; reparents the lines to those new paragraphs; and deletes the original paragraphs.
' Take each line and make it its own paragraph
Dim originalParagraphs As ContextNodeCollection = _
theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Paragraph)
Dim lines As ContextNodeCollection = _
theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Line)
Dim lineNode As ContextNode
For Each lineNode In lines
' Create a new alignment level and paragraph
Dim lineParagraph As ContextNode = lineNode.ParentNode
Dim writingRegion As ContextNode = lineParagraph.ParentNode
Dim newParagraph As ParagraphNode = _
CType(writingRegion.CreateSubNode(Microsoft.Ink.ContextNodeType.Paragraph), ParagraphNode)
' Reparent the line
lineNode.Reparent(newParagraph)
Next lineNode
' Remove original paragraphs and alignment nodes
Dim originalParagraph As ContextNode
For Each originalParagraph In originalParagraphs
Dim originalAlignmentLevel As ContextNode = originalParagraph.ParentNode
originalAlignmentLevel.DeleteSubNode(originalParagraph)
originalAlignmentLevel.ParentNode.DeleteSubNode(originalAlignmentLevel)
Next originalParagraph
// Take each line and make it its own paragraph
ContextNodeCollection originalParagraphs =
theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Paragraph);
ContextNodeCollection lines =
theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Line);
foreach (ContextNode lineNode in lines)
{
// Create a new paragraph
ContextNode paragraph = lineNode.ParentNode;
ContextNode writingRegion = paragraph.ParentNode;
ParagraphNode newParagraph = (ParagraphNode)
writingRegion.CreateSubNode(Microsoft.Ink.ContextNodeType.Paragraph);
// Reparent the line
lineNode.Reparent(newParagraph);
}
// Remove original paragraphs
foreach (ContextNode originalParagraph in originalParagraphs)
{
ContextNode originalWritingRegion = originalParagraph.ParentNode;
originalWritingRegion.DeleteSubNode(originalParagraph);
}
