Pass A Stringbuilder Info To A Label?

i have a stringbuilder which loops thru the items details of my shopping cart like below:

StringBuilder sbo = new StringBuilder();
for (int i = 0; i != Cart.Order.Items.Length; ++i)
{
sbo.AppendLine(
string.Format(
"{0} {1} {2} {3} <br />",
Cart.Order.Items[i].ItemNumber,
Cart.Order.Items[i].ProductTitle,
Cart.Order.Items[i].Size,
Cart.Order.Items[i].Price.ToString("c")
)
);
}

now i would like to bind these details to 4 labels like lbItemno, lbProdTitle, lbSize, lbPrice.
