Why ASP.NET Web Forms Still Holds Value in Modern Development
Written on
Chapter 1 - A Retrospective on ASP.NET Web Forms
ASP.NET Web Forms may be perceived as outdated according to contemporary software engineering standards. Admittedly, this sentiment might reveal my own experience, but it's a valid observation. In the realm of software, even a decade can significantly impact perceived relevance. My journey with Web Forms began shortly after their debut by Microsoft in 2003.
Throughout my college years, I immersed myself in Web Forms, and approximately 80% of my professional experience has been centered around this framework. Consequently, I have developed a strong affinity for it, which is unusual for frameworks. While I've extensively used ASP.NET MVC 5 and experimented with React, neither has evoked the same level of enjoyment for me. Web Forms, however, resonate differently.
Drawing a parallel, it's akin to a driver of an electric vehicle cherishing the roar of a 1969 Shelby engine. The craftsmanship, power, and nostalgia associated with Web Forms contribute to their charm in software development. Yet, there are even more reasons to appreciate them.
Section 1.1 - The Power of Server Controls
For those unfamiliar, server controls are pre-designed web components that come with extensive functionality, seamlessly compiling into modern, compliant HTML. These include elements like buttons, links, and images, which the server can manage directly, eliminating the need for additional effort. Each control can have server-side event handlers, such as those for button clicks or change events, with Visual Studio simplifying event binding—often with just a keystroke.
However, in today's AJAX-driven environment, server controls may begin to feel dated, as full-page postbacks are increasingly rare. This makes binding a server-side 'change' event to a dropdown less common in 2021. Fortunately, Microsoft anticipated this need and introduced the UpdatePanel control, enabling content rendering without full-page postbacks. This control simplifies AJAX functionality for server controls, allowing you to implement it effortlessly by dragging controls into the panel.
What truly captivates me is the overall simplicity of this framework.

Section 1.2 - The Flexibility of User Controls
User controls can be viewed as custom server controls, allowing developers to create reusable components tailored to their specific functionality and properties. This feature facilitates the easy integration of these components into any web form, with individual configuration through their properties.
The real advantage emerges when utilizing third-party custom user controls developed over the years. From fully responsive diagram editors to sophisticated word processors, the spectrum of available controls is impressive. Developers can also create generic controls that function across various ASP.NET web applications, which is particularly beneficial for someone like me, managing several Web Form projects.
If you're familiar with React, user controls are reminiscent of the Component system, offering standalone modules capable of data sharing with parent components or other controls.
Chapter 2 - The Significance of the Page Life Cycle
The ASP.NET Page Life Cycle is ingrained in my memory, much like the alphabet. This is largely due to its prominence as a common interview topic during the mid-2000s. Understanding this life cycle is crucial, particularly for Web Forms developers.
In brief, the life cycle encompasses a series of stages that every page undergoes for rendering, including start, initialization, loading, rendering, and unloading. The best part is that you have access to event handlers at each stage, granting you the ability to configure or set up elements before or after the page loads.
I have yet to encounter another framework that provides such granular control over the page rendering sequence. While not the most frequently used feature, there are instances where preprocessing controls or modules becomes essential.
Section 2.1 - Clarity of Code-Behind
One of the standout features of Web Forms is the clear distinction between client-side and server-side logic. ASP.NET achieves this by dividing each web page into two distinct files: one for client-side code (including server controls) and another for server-side event handlers, such as button clicks or page load events.
These two files communicate through various methods. Server-side pages can manipulate the DOM and server controls, while client-side pages can incorporate server-side tags that render before the page loads. Additionally, developers have the option to compile the project such that updates to the client-side page do not necessitate recompiling the entire project—only changes to the server-side code behind would require recompilation. This feature is invaluable for front-end-heavy development, where frequent small adjustments occur.
For me, this separation of client and server-side logic is straightforward and efficient. Every team member knows exactly where to find event handlers without having to sift through convoluted project or directory structures common in other frameworks.
Section 2.2 - Developer Loyalty
If you ask any seasoned .NET developer with Web Forms experience if they would switch to a different framework, I would bet that most would respond with skepticism. Particularly those who have delved deeply into the framework, uncovering obscure bugs and eventually finding even more obscure solutions.
I've found myself in similar scenarios, grappling with challenging issues, only to be rewarded with a successful compiler message, restoring hope. This emotional connection fosters loyalty to the framework. It has served me well, and I've encountered few challenges that felt insurmountable. My hope is that Microsoft continues to recognize the extensive community of developers who have dedicated their careers to mastering this environment.
However, it's worth noting that Microsoft has suggested transitioning to Razor Web Pages instead of continuing with Web Forms. Without plans to migrate Web Forms to .NET Core, one can't help but wonder about its longevity.
Until such a day arrives, I will continue to embrace and advocate for ASP.NET Web Forms, sharing my enthusiasm with anyone willing to listen—nearly two decades after its introduction.
