Dim instance As ContextNode
Dim value As StrokeCollection

Property Value

The StrokeCollection associated with this ContextNode.

Remarks

If the ContextNode is not a leaf node, this property returns the strokes of all its leaf descendants.

If the node is of a type that does not have strokes, such as TextWordNode, ImageNode, or AnalysisHintNode, this property returns an empty strokes collection.

Example

This example is a method that assigns a red DrawingAttributes to the strokes of a ContextNode and assigns the default drawing attributes to all other strokes. An InkCanvas, theInkCanvas, collected the strokes.

Sub MarkNodeAsRed(ByVal selectedNode As ContextNode)
    ' Set all node strokes to black, but this one to red
    Dim stroke As Stroke
    For Each stroke In Me.theInkCanvas.Strokes
        If Not (selectedNode Is Nothing) AndAlso selectedNode.Strokes.Contains(stroke) Then
            stroke.DrawingAttributes.Color = Colors.Red
        Else
            stroke.DrawingAttributes.Color = Me.theInkCanvas.DefaultDrawingAttributes.Color
        End If
    Next stroke
    
End Sub 'theResultsTreeView_SelectedItemChanged

private void MarkNodeAsRed(ContextNode selectedNode)
{
    // Set all node strokes to black, but this one to red
    foreach (Stroke stroke in this.theInkCanvas.Strokes)
    {
        if (selectedNode != null &&
            selectedNode.Strokes.Contains(stroke))
            stroke.DrawingAttributes.Color = Colors.Red;
        else
            stroke.DrawingAttributes.Color = 
                this.theInkCanvas.DefaultDrawingAttributes.Color;
    }
}
