ASP Connectionstring not working

I have this ASP Connection string for my MasterDetail Gridview but I keep getting an error that states that it's an incorrect syntax near '?'.  I'm using a session where clause to grab masterdetail information from the main gridview. Not sure where I can change or what i'm doing wrong. Thanks

SelectCommand="SELECT OrderDetailID, OrderID, ProductCode, SUBSTRING(ProductName, 5, LEN(ProductName)) AS ProductName, Quantity, ProductPrice, TotalPrice FROM OrderDetails WHERE ([OrderID] = ?)"

Open in new window

Sorry but this is not a connection string. You may refer to connection strings at www.connectionstrings.com

It is the SelectCommand after my Connectionstring.  I'm still coming up with the error either or and my error is still the same.

<asp:SqlDataSource ID="sqlPrintedDetails" runat="server" ConnectionString="<%$ ConnectionStrings:ApplicationServices %>" SelectCommand="SELECT OrderDetailID, OrderID, ProductCode, SUBSTRING(ProductName, 5, LEN(ProductName)) AS ProductName, Quantity, ProductPrice, TotalPrice FROM OrderDetails WHERE ([OrderID] = ?)">

try something like below.
cmd = new SQLCommand("SELECT OrderDetailID, OrderID, ProductCode, SUBSTRING(ProductName, 5, LEN(ProductName)) AS ProductName, Quantity, ProductPrice, TotalPrice FROM OrderDetails WHERE OrderID = @orderID)"", conn);
cmd.Parameters.AddWithValue("@orderID", value); //session value
cmd.Prepare();
cmd.executenonquery();

hope this helps.
