sqlcommand timeout using looping vb.net - sql-server

Question

may this code explain my problem,
dim dgv1 as new datagridview
dim dgv2 as new datagridview
dim dgv3 as new datagridview
dim dgv4 as new datagridview
sub processData()
conn = new sqlconnection(strcon)
conn1 = new sqlconnection(byconn)
conn.open
conn1.open
dim trans as sqltransaction = conn.begintransaction
dim trans1 as sqltransaction = conn1.begintransaction
try
dim con1 as new sqlconnection(strconn)
con1.open
dim cmd as new sqlcommand("some query",con1)
cmd.commandtype = commandtype.storedprocedure
dim da as new sqldataadapter(cmd)
dim dt as new datatable
da.fill(dt)
con1.close
dgv1.datasource = dt
for i as integer = 0 to dgv1.rowcount -1
getData2(i)
for j as integer = 0 to dgv2.rowcount -1
getData34()
end for
saveData1(i,conn,trans)
saveData2(conn1,trans1)
next
trans.commit
trans1.commit
conn.close
conn1.close
catch ex as exception
trans.rollback
trans1.rollback
conn.close
conn1.close
end try
end sub
sub getData2(i as integer)
dim con1 as new sqlconnection(strconn)
con1.open
dim cmd as new sqlcommand("some query",con1)
cmd.commandtype = commandtype.storedprocedure
cmd.parameters.addwithvalue("#PARAM",dgv1.item(0,i).value)
dim da as new sqldataadapter(cmd)
dim dt as new datatable
da.fill(dt)
con1.close
dgv2.datasource = dt
end sub
sub getdata34(i as integer)
dim con1 as new sqlconnection(strconn)
con1.open
dim cmd as new sqlcommand("some query",con1)
cmd.commandtype = commandtype.storedprocedure
cmd.parameters.addwithvalue("#PARAM",dgv2.item(0,i).value)
cmd.parameters.addwithvalue("#TYPE","LEFT")
dim da as new sqldataadapter(cmd)
dim dt as new datatable
da.fill(dt)
dgv3.datasource = dt
cmd =new sqlcommand("some query",con1)
cmd.commandtype = commandtype.storedprocedure
cmd.parameters.addwithvalue("#PARAM",dgv2.item(0,i).value)
cmd.parameters.addwithvalue("#TYPE","RIGHT")
da =new sqldataadapter(cmd)
dt =new datatable
da.fill(dt)
dgv4.datasource = dt
con1.close
end sub
sub saveData1(i as integer,cn as sqlconnection, trans as sqltransaction)
'some query with transaction
end sub
sub saveData2(cn as sqlconnection, trans as sqltransaction)
'some query with transaction
end sub
While processData called, in function getData2 and getData34 always give me timeout error message. adding timeout in sqlcommand not help me.
adding OPTION (RECOMPILE) in stored procedure also not help.
Perhaps, I miss something.
