How do you specify what happens when a user selects a button or control?

The proper way to specify what occurs when a user selects a button or control within Power Apps is to set the OnSelect property to the desired formula. This property dictates what actions should be taken in response to the selection event, allowing developers to create dynamic and interactive applications. The formula you assign to the OnSelect property can include various functions, such as navigating to different screens, updating data, or triggering workflows.

When a user interacts with a control, such as a button, the OnSelect property provides the mechanism to define the response to that selection effectively. This is fundamental in Power Apps since it empowers users to initiate actions and manipulate data directly from the user interface.

The mention of the click wizard is not relevant here, as the wizard does not define action behavior in the same direct manner. The OnClick property is typically associated with other programming environments and is not applicable in the context of Power Apps, where the OnSelect property is the specific one used. Lastly, stating that Power Apps cannot run formulas based on user selections is factually incorrect, as executing formulas based on user actions is a core feature of the platform.
