Summary

In this chapter, we delved deep into enhancing user experience through effective validation, prompts, and alerts. We explored the power of ObservableValidator for validation logic and learned the nuances of showing errors both as a collective list and inline, right next to input fields. With triggers, we learned how to customize UI elements without reinventing the wheel. We also explored using an IDialogService leveraging alerts and prompts, which is essential in contexts where user feedback or confirmations, such as during critical actions or navigations, are required. As we move forward, we’ll pivot to a vital aspect of many modern apps: making remote API calls.
