>I have a form, on this form I a series of tab page frames. On page2 I have a grid, I would like this Grid to be initialized only when I click on the tab page2. The reason behind this is for performance, as well I am using a common table which will hold different values of data based upon whether the user is in page1, page2 or page3.

In the page.activate:

IF TYPE( "this.Grid1.name" ) = "C"
  THIS.ADDOBJECT( "grid1", blah, blah, blah)
ENDIF

Do you want to rebuild the grid each time? You could remove object first.
