I have an application that is centered around a database (ORM is LINQ-SQL) that has a table called Assignment. I am using the repository pattern to manipulate the database. My application is basically going to perform CRUD operations. I am new to delegates and events and I am asking you what events I should create (like maybe AssignmentCreating, AssignmentCreated) and what kind of delegate to use (like maybe a custom delegate or just an EventHandler)? UPDATE: My application has a ListView with some columns that show some data. On the right side, I have a panel with textboxes binded to the values of the currently selected assignment. Like a textbox for Score, one for title, etc. and they are all editable. That deals with the Read and Update. Then I have a custom dialog box that has the same kinds of textboxes, and the dialog Creates new assignments. Then users can just select an assignment and Delete it via the Delete button, or a context menu.
