WinForms Development Best Practices for 2024

Windows Forms (WinForms) is one of the best toolsets in your development arsenal. WinForms has been a powerful addition to Visual Studio, providing one of the most productive ways to create intuitive and beautiful desktop apps. Its continued support is a massive step in the right direction.

With the start of a new year, WinForms will continue to become a powerhouse in developing rich and meaningful apps with an engaging user interface. We've compiled a list of best practices to consider incorporating into your team's work mantra or as a checklist and refresher when using WinForms next.

Structuring Code for WinForms

A clear structure is imperative for development, and it is vital to have a clear view of everything that happens from start to finish. Developing WinForms apps benefit from a concise and transparent process you can achieve through design patterns and best practices while using them. 

A Model-View-Controller (MVC) or Model-View-Presenter (MVP) are great ways to tackle your data management, processes, and code. Using either of these architectural patterns ensures the separation of concerns, significantly improving your topology flow. Keeping UI logic distinct from business logic allows you to provide users with a better experience to focus on how you display data, receive user input, provide updates, and ultimately - handle crucial events.

Design patterns such as Singleton and Observer allow you to organize a more salable code base further. The Singleton pattern is beneficial for managing application-wide resources, while the Observer pattern will let you handle updates and essential events between components.

Asynchronous Programming and Responsiveness

Asynchronous programming techniques are a great way to help further your comprehensive use of WinForms apps. Using 'async' and 'await' as keywords is beneficial in performing time-consuming operations - all without freezing and crashing the user interface. Using asynchronous programming techniques provides a better and more responsive experience for your users.

A great example of where this is beneficial is for essential tasks such as file I/O, large database operations, updates, or ongoing network requests.

It's also important to consider your threading. This will ensure UI updates occur on the main UI thread to prevent cross-threading issues. Use the Control.Invoke method when necessary to marshal calls to the UI thread.

Further Streamline Data Management

Data management does not have to be complicated but requires a strategic approach. Your primary goals are to confirm that you have proper storage of information, optimal handling of that information, and, most importantly - being able to retrieve that information when necessary. Part of the solution is always where to find it, and data binding helps to make this a lot easier. 

Data binding helps you connect data sources and their UI controls better. You will have a better-managed and more streamlined codebase, which lets you automatically update and maintain the data to a higher degree of effectiveness. Doing this will significantly reduce your UI-related code's complexity and promote a responsive and user-friendly experience. Remember to use the 'BindingSource' class!

ComponentOne's FlexGrid lets you have greater control over your data and display it in tabular form. For example, you can conduct on-demand loading through DataCollection to achieve better data virtualization in extensive datasets. 

WinForms: Your Best Way to Deliver Aesthetic Apps

User expectations will continue to evolve in this ever-changing environment, and developers must keep up with the increased demand. Touch and mobile experiences are becoming the norm for every application, regardless of the device. The best practices we have listed here will help you stay on top of data management and code structure and provide a more responsive experience for your users. Get an easy way to detect complex touch gestures such as pinch, swipe and flick using our TouchToolkit.

WinForms UI Controls help you stay on top of your organization, allowing you to implement faster data grids and customization and deliver modern applications. Let this new year be where your WinForms development reaches new heights.
