I am asking this question since I would like to know what is the best method of coding in a C # 2010 web form page that I just wrote. I read somewhere that everytime you need a datacontext object, you should create it. There was no reference also to removing
the datacontext object.
Thus on the current web form page that I am using that connects to a sql server 2008 r2 database, I am doing the following:
1. I never remove the AttDataContext from memory.
2. On the same web page, I am referring to the same linq to sql *.dbml file. However depending upon what I user clicks on, I have the following 3 datacontext objects:
a. AttDataContext,
b. Att2DataContext,
c. Att3DataContext.
Can you tell me if the above if a good idea or not? If not, can you tell me how I should use the same data context object on the same web
Can you tell me if the above if a good idea or not? If not, can you tell me how I should use the same data context object on the same web
Yes I think you can use them dynamically because each data context maps to a different kind of database with tables；But in order to make this more flexiable，I prefer to use DataSet+DataTables，this will let you dynamically create them and use。

I am using the datacontext in the following locations:
1. On the Page_load when (!IsPostBack),
2. I am also using the datacontext when the user clicks the 'next' button to update the database on web page 1 and web page 2.
