![]() ![]() The value of FirstName.Text is compared against "Carlos", "Kirstin", and "John" in that order. Switch( FirstName.Text, "Carlos", Navigate( Screen1, ScreenTransition.None ), "Kirstin", Navigate( Screen2, ScreenTransition.None ), "John", Navigate( Screen3, ScreenTransition.None ) ) The display goes back to the screen that was previously shown. The Back function was provided as a DefaultResult, so it runs. Without the ! operator, the condition is false, so the Navigate function doesn't run. If( IsBlank( FirstName.Text ), Navigate( Screen1, ScreenTransition.None ), Back() ) If FirstName were blank, this formula would have no effect. You can use the IsBlank function to test whether a required form field has been filled in. The condition is true, so the Navigate function runs. If( ! IsBlank( FirstName.Text ), Navigate( Screen1, ScreenTransition.None ) ) In these examples, a Text input control named FirstName has the value "John" typed into it. A DefaultResult was provided, so it's returned. The slider's value doesn't match any value to be checked. The slider's value matches the second value to be checked, and the corresponding result is returned. The slider's value matches the first value to be checked, and the corresponding result is returned. If( Slider1.Value > 1000, "Result1", Slider1.Value > 50, "Result2", "Result3")īoth the first and second conditions are false, a DefaultResult was provided, and it's returned. ![]() The second condition is true because the slider's value is a number, and the corresponding result is returned. The first condition is false because the slider isn't blank. If( IsBlank( Slider1.Value ), "Result1", IsNumeric( Slider1.Value ), "Result2" ) The second condition is also true, but it isn't evaluated because it appears later in the argument list than a condition that evaluates to true. The first condition is true, and the corresponding result is returned. The condition is false, a DefaultResult was provided, and it's returned. The condition is false, and no DefaultResult was provided. The condition is true, and the corresponding result is returned. In the following examples, a Slider control (named Slider1) has a value of 25. If you don't specify this argument, blank is returned. If an exact match isn't found, this value is returned. The corresponding value to return when an exact match is found. If an exact match is found, the corresponding Result is returned. Values to compare with the result from Formula. The value to return if no condition evaluates to true. The corresponding value to return for a condition that evaluates to true. Such formulas commonly contain comparison operators (such as, and =) and test functions such as IsBlank and IsEmpty. Conditions and matches are evaluated in order, and they stop if a condition is true or a match is found.īlank is returned if no conditions are true, no matches are found, and you don't specify a default result. You can use both of these functions in behavior formulas to branch between two or more actions. You can also use If in this case, but you'd need to repeat the formula for each possible match. Use Switch to evaluate a single condition against multiple possible matches.In Power Apps (unlike Microsoft Excel), you can specify multiple conditions without having to nest If formulas. Use If to evaluate multiple unrelated conditions. ![]() The most common syntax for this function is If( Condition, ThenResult, DefaultResult ), which provides the common “if … then … else …” pattern seen in other programming tools.
