How to Use the Power Fx Defaults  Function in Power Apps

What is the Defaults Function?

The Defaults function is a Power Fx function that allows you to set default values for controls in your app. This function is commonly used in forms, where you can pre-populate fields with default values. For example, if you have a form for creating a new customer, you can use the Defaults function to set the default value for the customer’s country to United States.

Using the Defaults Function in Power Apps

The Defaults function can be used in many ways in Power Apps. In this section, we will look at some of the most common ways to use this function.

Default Values in Forms

Forms are a common use case for the Defaults function. In a form, you can use the Defaults function to set default values for fields. To do this, you can simply set the Default property of the control to the desired value. For example, if you have a form for creating a new customer, you can set the Default property of the country field to “United States”. When the form is opened, the country field will be pre-populated with the default value.

Default Values in Dropdowns

Dropdowns are another common use case for the Defaults function. In a dropdown, you can use the Defaults function to set the default value that is selected when the dropdown is opened. To do this, you can set the Default property of the dropdown to the desired value. For example, if you have a dropdown for selecting a customer’s country, you can set the Default property to “United States”. When the dropdown is opened, “United States” will be selected by default.

Default Values in Galleries

Galleries are a powerful component in Power Apps that allow you to display a collection of items. You can use the Defaults function to populate a gallery with data when the app is opened. To do this, you can set the Items property of the gallery to a collection of data that you want to display. For example, if you have a gallery for displaying a list of customers, you can set the Items property to a collection of customer data. When the app is opened, the gallery will be populated with the customer data.

Using the Defaults Function with Variables

Variables are another powerful feature in Power Apps that allow you to store and manipulate data. You can use the Defaults function with variables to set default values for the variables. To do this, you can set the Default property of the variable to the desired value. For example, if you have a variable for storing the selected country, you can set the Default property to “United States”. When the app is opened, the variable will be pre-populated with the default value.
