Introduction to ASP.NET Web Forms

ASP.NET Web Forms introduced a set of server controls that developers could use to create dynamic web applications with ease. These controls offered an event-driven programming model similar to traditional Windows applications. Here's a list of some of the most commonly used Web Form controls:

Basic Controls:

Session Size Limit	- Limited by server resources and configuration settings.	N/A (Explanation only)
ViewState Security	- Can be easily tampered with by the client.	N/A (Explanation only)
Session Security	- More secure as data is stored on the server side.	N/A (Explanation only)
ViewState Performance	- Generally has better performance due to client-side storage.	N/A (Explanation only)
