You need to cast the Page with proper Page class.

For example,

((CustomerPage)this.Page).SaveData();

You should start getting intellisense right after "Page)"...

If that doesn't work, try this.

  CustomerPage loCustomerPage = (CustomerPage) (this.Page)
  loCustomerPage.SaveData()

>In the click even of one of the buttons on the usercontrol, I have the code

>this.Page.SaveData();

>When I compile, I get "'System.Web.UI.Page' does not contain a definition for 'SaveData'"

>>Usercontrols have a property called "Page" which is a reference to the page object that contains the instance of the usercontrol. Use this property to run any methods of the page.
>>
>>>I have a usercontrol of buttons that I use as a toolbar for pages. How do I reference a method of the page (that the control is dropped onto) from the click event of one of the buttons.
>>>
>>>For instance from the Save button, I want to call the SaveData() method of whatever page the control is on.
