Show Data In A Txtbox Based On A Key Passed From The 1st Page

On my Home page I have a gridview that has Four columns: CustomerID, Product, Quantity, then a link (which appears on each row..called View). When a user clicks View on a particular row it will then send that particular CustomerID to the next page (CustomerProfile.aspx).

On the CustomerProfile.aspx page I have a textbox where the Customer Name should appear. How do I go about displaying the customer name in the textbox based on the CustomerID passed to the customerprofile.aspx page? Do I need to call a stored procedure? Do i need to call the Customer Table in my code?

(i'm using C#) Thanks!! Ur help is very much appreciated!

Side Note: i am passing the CustomerID by a SESSION variable called customerID ~~~>this is in my pageLoad method labelCustomerID.Text = Session["customerID"].ToString();

but i'm wanting to have the Customer Name in a textbox based on the above ^^^ session variable. My textbox is called txtCustomerName.Text

*** Customer Table***
CustomerID
CustomerName
CustomerAddress

^^^wanting to call the customer name and put it in the customer name text box based on the particular customerID
