Part 5: Business Logichttp://www.asp.netWed, 22 May 2013 15:31:19 GMTumbracoComments for Part 5: Business LogicenComment Posted by dlazendihttp://www.asp.net/web-forms/tutorials/tailspin-spyworks/tailspin-spyworks-part-5Thu, 13 Jan 2011 06:43:34 GMT00000000-0000-0000-0000000011499Hi,

Great work on this application... I'm having a problem with my database...

I get error at this part

---------------------------

throw new Exception("ERROR: Unable to Add Item to Cart - " +

exp.Message.ToString(), exp);

}

}

}

-----------------------------------

The error is:

Server Error in '/' Application.

Cannot insert explicit value for identity column in table 'ShoppingCart' when IDENTITY_INSERT is set to OFF.

I tried the other method to set IDENTITY_INSERT ON but still no success...

I was wondering if there is something i should change in my database....

Thank you very much...

I generated my own membership and commerce database on SQL Server 2008.

I learned lots of knowledge about ASP.NET 3.5/4.0 and SQL Server 2005/2008

I really appreciate this video tutorials. Thanks so much! Joe!!

How can I make the MyShoppingCart.cs know that is is part of the MyShoppingCart.aspx ? The issue is that the GetShoppingCartId() method wont work because you cant use the Session property.

Thanks Jon

I just recreated the MyShoppingCart.cs file in the main Project folder and it found the MyShoppingCart.aspx page and set up the partial class corrrectly then I just copied the MyShoppingCart.cs back to the Class folder of the project
