Extending Microsoft Power Apps with Power Apps Component Framework

By: Danish Naglekar

Overview of this book

Power Apps Component Framework is used by professional developers to extend the capabilities of model-driven and canvas apps. Extending Microsoft Power Apps with Power Apps Component Framework will take you through the basic as well as advanced topics using practical examples. The book starts by helping you understand the fundamentals of the framework, its lifecycle, and the tools that you'll use to build code components using best practices and file management guidelines. You'll then learn how to extend Power Apps step by step and apply the principles and concepts covered in the book to build code components for field type attributes. The book covers different ways of debugging code components and guides you through the process of building code components for datasets. You'll also explore the functions and methods provided by the framework to enhance your controls using powerful sets of libraries and extensions. As you advance, you'll get to grips with creating and managing authentication profiles, discover different ways of deploying code components, and configure code components in model-driven and canvas apps. Finally, you'll learn some of the important features of the framework and learn modern web development practices. By the end of this Power Apps book, you'll be able to build, debug, enrich, and deploy code components confidently.

Implementing pagination on a dataset

Every dataset code component will need to implement pagination because when you configure your code component on a sub-grid or a view of the application, it provides you with a way to configure the number of records that will be initially displayed by your control. By default, on a sub-grid, this setting is set to 10 records, and on a view, it is set to 50 records.

If you recall when we built the dataset code component in Chapter 5, Code, Test, and Repeat, we added a Load More... button on the dataset that shows up when additional pages are available but is hidden when no additional pages are available. At that time, we did not add any logic to this button that would implement showing the data from those additional pages.

Now, we will add an event listener on this button in the init method and bind it to a function that will perform pagination. The following is the code for the function that will perform the pagination:
