As you've posted this in the LINQ forum, I'm going to assume that you are using LINQ to SQL or LINQ to Entities (Entity Framework) for data access. In that case you query that table and select just that column and then call the Sum method of your query result. You can display that number in a TextBox like you would any other number.
