Hi Alexander,

	In single line mode , there is no rich edit control style to handle EOL.
	Referenced documentation: https://msdn.microsoft.com/en-us/library/windows/desktop/bb787605(v=vs.85).aspx

Many Thanks

   The TextField is based on Rich Edit control on Windows. Does the Rich Edit control have properties to properly handle multiline strings in single-line mode?
