Maintaining State Per Page in ASP.NET Web Applications. Download source - 17.9 KB Introduction This article discusses an approach to build ASP.NET pages that maintain their state between requests. Let me give an example: A user, Hugo, selects a year in the year-selection DropDownList on a page. Unfortunately, he decides to navigate to another page of my web application before continuing to enter data on my page.
Later on, Hugo returns to my page and wants to continue entering data. What's so special about my approach? Actually, nothing. Using the code The StatePage class is a base class for all my pages that want to make use of their own state. PageState: Contains the state of a single page. Both state objects are read from the Session when the page is initialized, and stored back to the Session when the page is rendered.

Using ADO.NET for beginners. Download source files - 28.3 Kb Introduction This is a simple ADO.NET database application that returns results from a database table, writes the output to a DataGrid and TextBoxes, and uses Buttons (First, Previous, Next, Last) to navigate through the records.

Like everyone else I also searched for a most requested method in MSDN Library to trap the keystrokes (Up, Down, Esc...) in Windows Forms and included it in the code because some users asked me desperately for that. You can find the other requested methods as well to get the contents of a cell/row in a DataGrid. I chose Microsoft Access database (as reflected in the ADO.NET OleDb objects) because it's easy to use and you don't need to have Microsoft SQL Server running.
