Getting Started with Power Apps – A Comprehensive Guide to StartsWith Functionality




Power Apps is a powerful tool developed by Microsoft that allows users to create custom business applications without the need for extensive coding knowledge. One of the important functionalities in Power Apps is the StartsWith functionality, which allows users to efficiently search and filter data based on the starting characters of a string. In this blog post, we will explore the StartsWith functionality in Power Apps and how it can be used in various scenarios.

Understanding StartsWith Functionality in Power Apps

The StartsWith function in Power Apps is used to determine whether a string starts with a specific set of characters. It takes two arguments – the string to be checked and the string to compare against. The function returns a boolean value, true if the string starts with the specified characters, and false otherwise.

StartsWith can be used in various scenarios, such as filtering a gallery based on user input, implementing a search functionality, or creating custom validation rules for data entry forms. It provides a flexible and efficient way to manipulate and analyze data within Power Apps.

Prerequisites for Using StartsWith in Power Apps

Before utilizing the StartsWith functionality in Power Apps, there are a few prerequisites that need to be considered:

Required licenses or subscriptions

To use Power Apps and access the StartsWith functionality, you will need an appropriate license or subscription. Review your organization’s licensing agreements or consult with the IT department to ensure you have the necessary access.

Access to Power Apps and related tools

In order to create and configure Power Apps with StartsWith functionality, you need access to Power Apps and related tools. Ensure that you have the necessary permissions and access rights to create and edit Power Apps.

Getting Started with StartsWith Functionality

Setting up and implementing StartsWith functionality in Power Apps can be done through the following steps:

Setting up a new Power App

To begin, create a new Power App or open an existing one in the Power Apps studio. The studio provides an intuitive interface for designing and customizing your Power App.

Adding a text input control

To utilize the StartsWith functionality, add a text input control to your Power App’s screen. This control will allow users to enter the search criteria based on which the StartsWith function will filter and display data.

Implementing the StartsWith function

In order to utilize the StartsWith function, access the properties of the control where you want to implement the functionality. Locate the “Visible” property and enter the StartsWith formula that compares the user’s input with the desired string. For example, if you want to filter a gallery based on user input in a text input control named “SearchInput”, the formula would be: StartsWith(GalleryData.Title, SearchInput.Text).

Testing the StartsWith functionality

After implementing the StartsWith functionality, test your Power App to ensure that the StartsWith function is working correctly. Enter different search terms in the text input control and observe the filtered data in the gallery or other relevant controls.

Advanced StartsWith Techniques and Examples

In addition to basic usage, the StartsWith functionality in Power Apps can be combined with other functions to create more complex and powerful applications. Here are some advanced techniques and examples:

Combining StartsWith with other functions

The StartsWith function can be combined with other functions like Filter, Sort, and LookUp to perform advanced data manipulations. For example, you can filter a gallery based on a combination of StartsWith and another condition using the Filter function: Filter(GalleryData, StartsWith(Title, SearchInput.Text) && Condition).

Filtering data using StartsWith

StartsWith can be used to efficiently filter data based on user input. For example, you can filter a gallery to display only the items where the title starts with the characters entered by the user in the search input control.

Creating a search functionality with StartsWith

By implementing the StartsWith functionality in Power Apps, you can create a powerful search functionality within your application. Users can enter specific characters or keywords, and the application can display the relevant data based on the matching results.

Troubleshooting StartsWith Issues

While using the StartsWith functionality in Power Apps, you may encounter some common issues. Here are some troubleshooting tips:

Common errors and their resolutions

If the StartsWith functionality is not working as expected, check for any error messages or formula-related issues. Ensure that the syntax of the StartsWith formula is correct, including the correct use of arguments and data types.

Debugging StartsWith formula errors

If you are experiencing issues with the StartsWith formula, use the built-in Power Apps formula checker and debugger to identify and resolve any issues. It can help validate the formula and troubleshoot any errors or unexpected behavior.

Best Practices and Tips for Using StartsWith in Power Apps

When using the StartsWith functionality in Power Apps, consider the following best practices and tips:

Optimal usage of StartsWith in different scenarios

Understand the specific requirements of your application and use the StartsWith functionality accordingly. Optimize the usage of StartsWith in different scenarios to ensure efficiency and performance.

Performance considerations when using StartsWith

While the StartsWith function is efficient, it’s important to be mindful of performance considerations. Avoid using StartsWith on large datasets or in nested formulas that could impact the overall speed and responsiveness of your Power App.

Useful tips and tricks for efficient StartsWith implementation

Explore and experiment with different techniques and approaches to efficiently implement the StartsWith functionality in your Power Apps. Utilize the vast resources and community support available for Power Apps to learn from others and improve your implementation skills.

Real-World Use Cases for StartsWith in Power Apps

The StartsWith functionality can be applied in various real-world scenarios. Here are a couple of examples:

Implementing a contact search feature

When developing a contact management application, you can utilize the StartsWith functionality to create a search feature. Users can enter part of a contact’s name or company, and the application can display the matching results using StartsWith.

Filtering a gallery based on user input

A common use case is to filter a gallery based on user input. By allowing users to enter search criteria, the gallery can dynamically display the data that starts with the entered characters, effectively narrowing down the results.


With the StartsWith functionality in Power Apps, users have a powerful tool at their disposal to efficiently search, filter, and manipulate data based on the starting characters of a string. This functionality provides flexibility and enhances the usability of Power Apps in a wide range of business applications. As you continue to explore and experiment with StartsWith in Power Apps, you’ll unlock even more opportunities to create intuitive and efficient user experiences. So, go ahead and start discovering the full potential of StartsWith in Power Apps!
