A conditional logic structure in Power Apps, this element allows evaluation of a single expression against multiple possible values. It returns a result corresponding to the first value that matches the expression. When no match is found, a default result can be specified. For example, it might be used to determine the text displayed based on a user’s selected option from a dropdown menu, where each option triggers a different text output.
The employment of such a conditional construct simplifies complex formulas and enhances the readability of Power Apps code. This contributes to more maintainable and understandable applications. Its capability to handle multiple conditions within a single expression streamlines development efforts, reducing the need for nested “If” statements and improving overall application performance. Its presence stems from the need for efficient multi-way branching within application logic.
