Is maintain the transaction with a static LINQ to SQL DataContext in asp.net possible?

I have ASP.NET application which is connected with SQL server using LINQ to SQL. Where as i have a static class , certainly it would work on application level. Where as I have created static object of DataContext in this static class.
I have not created any data context object in application except this. Where as i am using this static data context object for each data base manipulation.
