Displayin two datsets one below the other in a gridview

I am using VS 2005. See suppose i have datasets as ds1 and ds2 which contains
ds1                                                                                ds2
Vegetables  Cost                                            Fruit   COst
Carrot          20                                              Apple   20
Tomato       10                                               Grapes  10
 
Then i want my output to be displayed as
Carrot 20
Tomato 10
Apple 20
