Question Problem compare two grid view

[sfyong]

Hi Vb.net expert,

I have a problem..

I have two grid ...grid A and grid B..
grid A [name, age] grid B [ name, address, tel, age]

If gridA record already exist in grid B..
then, skip add record ..
else
add record
For Each gvRow As GridViewRow In gridA.Rows
For Each gvRow2 As GridViewRow In gridB.Rows

If (gvRow.Cells(0).Text.Equals(gvRow2.Cells(0).Text) And gvRow.Cells(1).Text.Equals(gvRow2.Cells(4).Text)) Then

else
'add record....
End If

Next
Next

I have problem about the looping..
Can anyone help me to solve..
Thanks..
