// Enable content selection.
flowDocScrollViewer.IsSelectionEnabled = true;
// Enable the toolbar.
flowDocScrollViewer.IsToolBarVisible = true;
// Set zoom between 50% and 1000%.
flowDocScrollViewer.MinZoom = 50;
flowDocScrollViewer.MaxZoom = 1000;
// Set the zoom increment to 5%.
flowDocScrollViewer.ZoomIncrement = 5;
// Set the initial zoom to 120%.
flowDocScrollViewer.Zoom = 120;
FlowDocument flowDoc = new FlowDocument(new Paragraph(new Run("Flow content...")));
flowDocScrollViewer.Document = flowDoc;
Dim flowDocScrollViewer As New FlowDocumentScrollViewer()
With flowDocScrollViewer
' Enable content selection.
.IsSelectionEnabled = True
' Enable the toolbar.
.IsToolBarVisible = True
' Set zoom between 50% and 1000%.
.MinZoom = 50
.MaxZoom = 1000
' Set the zoom increment to 5%.

Dim flowDoc As New FlowDocument(New Paragraph(New Run("Flow content...")))
.Document = flowDoc
End With
