PowerApps Conditional Logic: Exploring If and Switch Functions with Examples

Delving into PowerApps Conditional Logic

Introduction:
In PowerApps, conditional logic is a fundamental building block, allowing for dynamic responses based on user input or other variables. The primary tools for introducing this logic are the If and Switch functions. This guide delves into their usage with illustrative examples, ensuring you can seamlessly integrate PowerApps Conditional Logic: If and Switch Functions into your apps.

Making the Most of If and Switch in PowerApps

Do you ever wonder how to efficiently categorize data, evaluate numeric ranges, or compare input values against specified conditions in PowerApps? The If and Switch functions are here to help. In this article, we will navigate through three prevalent scenarios where these functions shine.

For an in-depth technical reference, you can always refer to the official PowerApps documentation.

Grading with PowerApps: If Function in Action

Example 1: Categorizing Numeric Scores into Grades

Imagine you have student exam grades and you want to convert numeric scores into standard grades. Here’s how you can define the grading criteria:

• A – Score > 80
• B – Score 70-80
• C – Score 60-70
• D – Score 50-60
• E – Score 40-50
• Fail – Score < 30

Using the If function, the conversion becomes:

With({gradeInput:Value(txtGradeInput.Text)},
     If(gradeInput > 80, "A",
        gradeInput > 70, "B",
        gradeInput > 60, "C",
        gradeInput > 50, "D",
        gradeInput > 40, "E",
        "Fail"
     )
)

Example 2: Assigning Categories Based on Exam Names

When sorting exams by subject categories, you might have the following criteria:

• Sciences – Maths, Physics, Chemistry
• Arts – Music, Art, Dance
• Other – All other exams

The formula to execute this categorization is:

With({subjectInput:txtSubjectInput.Text},
     If(subjectInput in ["Maths", "Physics", "Chemistry"], "Sciences",
        subjectInput in ["Music", "Art", "Dance"], "Arts",
        "Other"
     )
)

Example 3: Labeling Numeric Levels with the Switch Function

The Switch function is perfect for direct comparisons. Consider a scenario where you’re tagging a ‘level’ number with descriptive labels:

• 1 – Beginner
• 2 – Intermediate
• 3 – Advanced
• Other – Unknown

Here’s the formula to achieve this:

Switch(Value(txtLevelInput.Text),
       1, "Beginner",
       2, "Intermediate",
       3, "Advanced",
       "Unknown"
)
