Reset function in Power Apps

The Reset function in Power Apps is used to reset the value of one or more controls on a screen to their default value. When a user interacts with a screen and modifies the value of one or more controls, the Reset function can be used to revert those changes and restore the original default values.

We cannot reset controls that are within a Gallery or Edit form control from outside those controls. We can reset controls from formulas on controls within the same gallery or form. We can also reset all the controls within a form with the ResetForm function.

Step 1: Insert a Text input control on a screen. By default, its name will be TextInput1 and its Default property will be set to "Text input".

Step 2: Type a new value in the text box.

Step 5: In the app preview mode. Select the button.

Step 6: The contents of the text box will return to the value of the Default property value i.e., “Text input”.
