Specialized form components are essentially an evolved form of regular form components, adapted for more specific tasks. Depending on the form’s purpose, specialized form components could include items such as product pickers for an eCommerce site, color pickers for a graphic design application, or date and time pickers in a calendar application. When used properly, these specialized form components can greatly enhance the efficiency and user experience of an application.
For example, a regular textbox might be satisfactory for capturing simple text input such as names or address information. But when it comes to capturing a date for scheduling an appointment, a regular textbox would not suffice. It would leave room for too many potential formatting errors and misunderstandings. However, a specialized date picker form component makes it easy for the user to input a date correctly. The component can be designed to restrict the user from entering dates that are in the past, or future dates that are too far ahead. Moreover, the date picker would ensure the date is formatted correctly so there’s no ambiguity (MM/DD/YYYY versus DD/MM/YYYY for example).
Power Platform’s Options for Specialized Form Components
Microsoft’s Power Platform provides a variety of ways to incorporate specialized form components into your application designs.
- Out-of-the-box components: These are readily available and require very little configuration. For example, date and time pickers, dropdown lists, radio buttons, etc.
- Custom Components: Developed either by you or other developers in Power Apps Component Framework (PCF). These are useful when the out-of-the-box components do not meet your specific requirements.
- External Components: Provided through third-party vendors and integrated into Microsoft Power Platform.
Here’s an example of how to implement a Date Picker in a Power App form:
DatePicker1.SelectedDate
In this script above, ‘DatePicker1’ is the name of our date picker component, and ‘.SelectedDate’ is the property used to retrieve the date selected by the user.
Why Use Specialized Form Components
There are several reasons why specialized form components should be used in application development:
- Enhanced User Experience: Specialized form components can make forms more intuitive and user-friendly, increasing user adoption.
- Data Validation: They help ensure that data is entered in a specific format or within certain parameters, reducing the chance of errors or inconsistencies.
- Efficiency: They can make it quicker to fill out forms, potentially saving substantial time for users.
- Reduced Development Effort: Many form components already exist, either out-of-the-box or through third parties, so using these can save development time and effort.
In conclusion, understanding and maximizing the use of specialized form components is critical for effective application development on the Microsoft Power Platform. By mastering this area, you will achieve one of the skills required to pass the PL-200 exam and become a proficient Microsoft Power Platform Functional Consultant.
