Remarks

If the TextPointer points to an ambiguous position, for example, between two lines, the line in the direction specified by LogicalDirection is selected as the relative starting line.

The operation performed by this property depends on a valid layout. When necessary, this method will attempt to automatically re-generate a valid layout before proceeding with the operation. Re-generating a layout can be a relatively expensive operation. Use HasValidLayout to check for a valid layout before performing operations that may re-generate the layout. For more information, see The Layout System.
