TabPage click event????

I have a user control that has a tab control on it.  I want to handle the tabpage click event on the form that contains the user control and can't seem to figure out how to do this.  I try to output messageboxes to test my form and nothing seems to happen.

When the user selects a tab, I want to take action (save to db,etc..)

It looks like I need to create a custom event to hanlde this. 

Any advice on how to do this is greatly appreciated.

Thanks in advance.
