vb.net - copying specific cell value from multiple dgv to a specific cell in all rows of dgv by loop -

i have 2 forms: form2 dgv, form3 tabcontrol having number of tab pages each of them dgv inserted. want cell(1) value of each row in form2 dgv equal value of cell(1) of row(13) in multiple dgv of form3 that:

 datagridview1.rows(0).cells(1).value = form3.datagridview1.rows(13).cells(1).value     datagridview1.rows(1).cells(1).value = form3.datagridview2.rows(13).cells(1).value     datagridview1.rows(2).cells(1).value = form3.datagridview3.rows(13).cells(1).value, etc. 

i trying following code:

for integer = 0 datagridview1.rows.count - 1        'dgv in form2          each tp tabpage in form3.tabcontrol1.controls.oftype(of tabpage)()             each dgv datagridview in tp.controls.oftype(of datagridview)()                  datagridview1.rows(i).cells(1).value = dgv.rows(13).cells(1).value             next         next     next 

but result, last dgv in form3 tabcontrol shows requested data rows of form2 dgv. missing, highly appreciated.

it because looping through tabpages inside of land on last tab i=0, i=1 etc

    dim integer = 0      each tp tabpage in form3.tabcontrol1.controls.oftype(of tabpage)()         each dgv datagridview in tp.controls.oftype(of datagridview)()             if < datagridview1.rows.count                 datagridview1.rows(i).cells(1).value = dgv.rows(13).cells(1).value                 1 += 1             end if         next      next
