Count of rows in Data Source

Hi all.

    I am trying to write my first AS Studio App and have a problem with getting the count of the number of rows of my data source.  I see that the number of rows command can be used, but should not be when using a data source.  So, my question is... what command can I use to get the total number of rows for my data source?

Here is what I have so far...

set table_View to table view "FolderList_TableView" of scroll view "FolderList_ScrollView" of window "Main_Window"
set data_source to data source of table_View


on idle theObject

(* Doesn't work *)
                repeat with i in every data row of data_source
                    
                    display dialog i
                    
                end repeat
       
        return 90
end idle



What is the correct code to use to get the count of the number of rows inside of a data source.  Should I use number of data rows even though I am using a data source?  Is there an easier command to go through each row individually?


Thanks in advance.


Chris
