public TextPointer DocumentStart { get; }

Property Value

Type: System.Windows.Documents.TextPointer
A TextPointer at the beginning of content in the text container associated with the current position.

Use the position returned by this property as a baseline position from which to work with relative offsets to other positions. The GetOffsetToPosition and GetPositionAtOffset methods provide a way to translate between positions and position offsets.

The Parent for the returned TextPointer is always a text container (TextBlock or FlowDocument), rather than a TextElement.
