User's Controls Save Event is not working

[Neeraj]

Hi


I have a master page , which have a tool Bar containing 4 Buttons like "Add , Save, Delete and Undo"
Content Page contains 4 Tabs like General, TimeCapture , Overtime , Sites, Each one is a User Control. and we need to perform 4 actions for Each tabs.

now i am Saving on Sites Tab but time it goes to my first Tab's Save Events how can i perforom Save Event of Sites TAb.
 
I have using Multiview for Tab switching.
 


Thanks in Advanced
