true if the layout is current and valid; otherwise, false.
Remarks
When necessary, operations that depend on a valid layout (such as the GetLineStartPosition method, GetCharacterRect method, and IsAtLineStartPosition property) attempt to automatically regenerate a valid layout before proceeding with the operation. Regenerating a layout can be a relatively expensive operation. Use this property to check for a valid layout before performing operations that may regenerate the layout. For more information, see Layout.
