A glance of the “OnLoad” event on a Model Driven App form (Async OnLoad event)

This blog will discuss a potential upcoming feature that is related to the “OnLoad” event of the forms for a model driven app. The goal is to look at the process of turning this event from synchronous to asynchronous using the “app settings” component. Also, some benefits of implementing an asynchronous logic on the “OnLoad” event will be illustrated.

Please note that, at the time of writing, the documentation points out that the “OnLoad” event is only synchronous. So, not all the following is supported yet. Hopefully this new feature will be documented and available to everyone soon.

Microsoft Docs (OnLoad Event):

The form OnLoad events are synchronous. However, you should not make synchronous network requests in an OnLoad event handler. This can cause a slow save experience and an unresponsive app. Instead, you should asynchronous network requests. Using asynchronous requests will dramatically improve the performance of form loads…
