If you just want to view your class members in sorted order without modifying the code then you can click on the A/Z icon on the outline view, as others have pointed out. Alternatively, you may wish to sort the class members in the code itself, in which case you should right click your source or source file name to get the context sensitive menu, then select Source(Alt-Shift-S), Sort Members.
It will pop up a dialog box allowing you to customize the sort, choose your desired options and click ok.
