In this tutorial I show you how to automatically increment a version number on a Dataverse record in Power Apps using JavaScript.

This is a short, focused video covering one specific but powerful technique. Every time a record is saved the version number updates automatically. No manual input, no human error, just clean automatic versioning built directly into your Model-Driven App.

What we cover:
1️⃣Writing a namespaced JavaScript function following Power Apps best practices
2️⃣Attaching the function to the On Save event of a Model-Driven App form
3️⃣Using setSubmitMode to ensure the value always persisted on save
4️⃣Testing the versioning behaviour live in the app

📌 JavaScript Function:
// Function to run on form save
function incrementVersionNumber(executionContext) {
// Get the form context from the execution context
var formContext = executionContext.getFormContext();

// Retrieve the current value of the youtube_versionnumber field
var currentValue = formContext.getAttribute("youtube_versionnumber").getValue();

// If the field is empty (first time), set it to 1
if (currentValue === null) {
formContext.getAttribute("youtube_versionnumber").setValue(1);
} else {
// Otherwise, increment the existing value by 1
formContext.getAttribute("youtube_versionnumber").setValue(currentValue + 1);
}

// Mark the field as dirty so the change is saved
formContext.getAttribute("youtube_versionnumber").setSubmitMode("always");
}

💡Replace youtube_versionnumber with your own column schema name.
