Ok,  found it out myself just now.

I wanted to catch a click on a row of a DataBrowsers GridView so I can 
display an image alongside with the name of the text in column 0 of the 
row clicked.
So I implemented an Observer to peek at the DataBrowser.GridView events, 
and it worked!

Something like this:

PRIVATE hObserver AS Observer

PUBLIC SUB Form_Open()

  hObserver = NEW Observer(DataBrowser1.GridView) AS "GridObserver"

END

PUBLIC SUB GridObserver_Click()

  DisplayProduct(DataBrowser1.GridView[DataBrowser1.GridView.Row, 0].Text)

END

I love this language!
