Building a C# WinForms App: DataGridView with Checkbox Filtering3 min read

Are you looking to elevate your C# WinForms skills? In this comprehensive tutorial, we’ll guide you through the process of creating a powerful WinForms application with a focus on DataGridView customization and checkbox filtering. Whether you’re a seasoned developer or just starting with C#, this tutorial will provide valuable insights into creating a user-friendly interface and implementing advanced data manipulation techniques.

WinForms remains a staple for desktop application development in the C# ecosystem, and the DataGridView control plays a pivotal role in displaying and manipulating data. We’ll kick off the tutorial by adding a DataGridView and a button to the form. Learn how to personalize the DataGridView for an enhanced user experience, including setting the ‘AutoSizeColumnsMode’ property to ‘Fill’ and the ‘SelectionMode’ property to ‘FullRowSelect’. These adjustments create a visually appealing and user-friendly interface for your application.

Central to our tutorial is the creation of a ‘Student’ class that serves as the data model for our application. In this section, we explore the process of adding a class to the project, defining properties such as ID, FirstName, LastName, Age, and IsInternationalStudent. By establishing a structured data model, we ensure that our DataGridView accurately represents and interacts with our data.

The tutorial progresses with a demonstration of how to load data into the DataGridView on form load. We introduce the LINQ (Language Integrated Query) approach to fetch and manipulate data efficiently. Whether you’re retrieving data from a source or working with a predefined list, the tutorial covers both scenarios. With this foundation, you’ll be well-equipped to handle dynamic data scenarios in your WinForms applications.

The tutorial reaches its pinnacle as we implement checkbox filtering for international students. Double-clicking the ‘Get International Students’ button triggers the application to filter and display only those students who are marked as international. Learn the essential LINQ code required for this functionality and witness how this feature enhances the responsiveness and user-friendliness of your WinForms application.

In conclusion, this tutorial provides a comprehensive guide to mastering DataGridView customization and implementing advanced features in C# WinForms. From creating a structured data model to utilizing LINQ for efficient data manipulation, this tutorial equips you with the knowledge to create robust desktop applications. Elevate your C# WinForms skills and build applications that stand out with a user-friendly interface and advanced functionality.
