the code is working fine

For Each row As Windows.Forms.DataGridViewRow In Me.DataGridView1.Rows()
  Dim searchVal as String
  searchVal = row.cell(1).value
  cmd.Parameters.Add("@name", SqlDbType.NVarChar).Value = searchVal
next row

I are Troll

For Each row As DataGridViewRow In DataGridView.Rows
    For Each cell As DataGridViewCell In row.Cells
        'Do your necessary test etc against each cell here
    Next
Next
