The table I am dealing with has over 100 columns and I am wanting to set my linq object propertychanged event and submitchanges or do I really have list out each property and set it equal to the new one?Below is an example of what I am trying to do:
Like that I have large number of controls on my form. I have dought, if I assigned like this, db.usp_ATI_FetchPatientDetails(iPatientID).ElementAt(0).Last_Name.ToString(); to every control, then I have set of controls like,

[Code]....
The use of "Select Customer.CustID", with or without the Distinct, causes this runtime error. CustID is a valid field in the table, and it shows up in intellinsense and compiles. If I just Select Customer, the error goes away, but Distinct doesn't know to look for distinct custid's.
DataBinding: 'System.String' does not contain a property with the name 'CustID'.

I am new to MVC and this really probably should not be posted here but in a different forum topic. The reason I am posting here though is I am not sure if there is something about MVC that would prevent me from doing what I am looking to do.So here it goes.Maybe I am the only one out there that thinks this way but I don't care for and don't fully understand LINQ. I Like building my stored procedures passing my data to a datareader etc... and displaying what I need.
Now that being said I am wanting to learn how to make a true Data Repository and build from there but everything I find online especially here all gives me examples and instructions on how to do so using LINQ.Does anyone know of a site that will teach me how to do this without using LINQ or any form of ORM just allow me to write my stored procs how they need to be and build my classes for data access how they need to be.I may be wrong in this but it seems to me this would be the more light weight way of doing it.Anyhow as stated above the additional question to this would be is there any reason this would not work for MVC and actually any reason it is extremely (or at least for me) hard to find any documentation on this anywhere online?
