This document discusses different methods of state management in ASP.NET including client-side techniques like view state, control state, hidden fields, cookies and query strings as well as server-side techniques like session state and application state. It provides examples of how each technique can be used to persist data across requests and compares their advantages and limitations. Client-side techniques store state on the client while server-side techniques store state on the server.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

6. Why is state necessary?
• The vast majority of Internet applications
operate using the HTTP protocol.
• HTTP is state less.
– This means that each request for a page is treated
as a new request by the server.
7. Introduction to State Management
• Remember that ASP.NET is stateless
– The Web server does not keep track of past client
requests
• Different technologies handle the issue of
statement management differently
– ASP.NET is quite unique in this regard
8. Types of State Management
• ASP.NET offers two categories of state
management
– Pure client-side statement management
– Server-side state management
10. State Management
(ViewState)
•
•
ASP.NET preserves the state of the page’s controls between
post backs by packaging and encoding it within a hidden
html field.
This view state feature can also be used programmatically to
preserve additional information between post backs for the
same page
Eg :-
ViewState["RequestCount"] = count;
int count = (int)ViewState["RequestCount"];
11. Advantages & Disadvantage of
View State
• It consumes no server memory.
• It is more hidden than Query String and Hidden
Fields
• Its possible to encrypt View State information.
Disadvantage :– It increases the size of the page.
12. State Management
(ControlState)
• The ControlState property allows you to
persist information as like the view state.
– The ControlState data is stored in hidden
fields.
13. Control State Application
• If we create a custom control that requires
view state to work properly.
• We should use control state to ensure other
developers don’t break your control by
disabling view state.
14. State Management
(Hidden Fields)
• Use the HiddenField control to store
persisted data.
• The data is stored in the Value property
• It’s simple and requires no server resources
15. State Management
(Query Strings)
• A query string can be used to submit data
back to the same page or to another page
through the URL.
Eg :string url = "productPage.aspx?id=" + id;
Response.Redirect(url);
productPage.aspx
int id = Convert.ToInt32(Request["id“]);
16. Disadvantages of Query String
• Not secured (its visible completely in the
address bar to the users)
• The maximum allowable length of a query
string varies from browser to browser(IE only
allows only 2k of url)
17. State Management
(Cookies)
• Cookies are a client-side approach for
persisting state information.
• These pairs accompany both server requests
and responses within the HTTP header
• Eg:HttpCookie cookie = new HttpCookie("Name",txtName.Text);
// Set expiry date to 1 day, 12 hours from now
cookie.Expires = DateTime.Now + new TimeSpan(1, 12, 0, 0);
Response.Cookies.Add(cookie);
18. Cookie Limitations
• While simple, cookies have disadvantages
• A cookie can only be 4096 bytes in size
• Most browsers restrict the total number of
cookies per site
• Users can refuse to accept cookies so don’t try
to use them to store critical information
20. Session state
• Session state is a server-based state
mechanism that allows you to store data in a
dictionary-style collection.
• It is scoped to the current browser session.
• That is, each user or browser session has a
different session state.
22. Application state
• Application state is a server-stored state
mechanism that allows you to store global
data in a dictionary-style collection that is
accessible from all pages in the Web
application.
23. Application state
• Thus, application state is ideal for storing
relatively small, frequently used sets of data
that do not change from user-to-user or
request to request.
• Eg :Application["SiteRequestCount"] = 0;
int count = (int)Application["SiteRequestCount";
