Property Valuetrue if the current position is at the beginning of a line; otherwise, false.
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.
