Mastering PowerApps: Comprehensive Guide to Resetting Variables and Form Controls

In the evolving world of PowerApps, ensuring efficient data management in forms and controls is crucial. Whether you’re building data input screens or advanced applications, understanding how to reset or clear data entry controls can greatly enhance user experience. In this guide, we’ll delve deep into techniques and best practices for resetting PowerApps variables and controls.

Grasping the Basics: The “Default” Property

At the core of resetting controls in PowerApps is the “Default” property. This integral property determines a control’s initial value. When a reset is performed on a control, it reverts to its defined default value.

1. The Classic “Reset” Property Technique

Every data input control in PowerApps comes with a “Reset” property. Activating this property by setting it to true returns the control to its original state. The key is to initiate this property from false, allowing the change in its state to trigger the reset. After setting it to true, it’s essential to revert it to false to maintain its functionality.

Implementation involves initiating a variable to false in the screen’s OnVisible property and toggling it true momentarily to activate the reset.

2. Embracing the Modern Reset Function

PowerApps now offers a more straightforward Reset function, eliminating some of the earlier method’s complexities. This function requires just the control’s name and promptly returns it to its default value. To reset a control named ‘txtDescription’, simply use the formula Reset(txtDescription). Remember, to reset form controls, the function must be called from within the form.

3. All-in-One: The ResetForm Function

For situations demanding a comprehensive reset of all form controls, PowerApps provides the ResetForm function. Just pass the form’s name, and voilà – every control returns to its default state. The function also accommodates any custom formulas you’ve defined in the form’s OnReset property.

4. Going Blank: Clearing Control Values

Sometimes, the need isn’t just to reset but to clear controls, leaving them empty. For creation-oriented data screens, reset techniques suffice. However, for edit screens, a unique approach is needed: leverage a Boolean variable to dynamically set control defaults.

Initialize this variable to false when the screen loads and toggle it true when needed. This ensures the control defaults to either a blank or its existing data value based on the Boolean’s state.


Mastering data control resets in PowerApps is essential for building efficient applications. From understanding the nuances of the “Default” property to leveraging the power of the Reset and ResetForm functions, this guide provides a comprehensive overview to empower your PowerApps journey.
