Dynamics 365 – Form OnSave Event

Implementing OnSave Event Handling

In Dynamics 365, you can incorporate a custom function to be called when the OnSave event is triggered using the following code example:

formContext.data.entity.addOnSave(myFunction);

By using this code, the myFunction is set up to handle the OnSave event, allowing you to run custom logic before the save operation.

Now let’s create an actual function to run during OnSave event. validateOpportunityScoreOnSave function performs validation checks on the opportunity score before the save operation is executed. This function ensures that the score aligns with predefined criteria or business rules, thereby maintaining data integrity and accuracy within the system.

	function OnLoad(executionContext){
	var formContext = executionContext.getFormContext();

	//Register custom event
	formContext.data.entity.addOnSave(validateOpportunityScore);
	}

	function validateOpportunityScoreOnSave(executionContext) {
	var formContext = executionContext.getFormContext();
	var opportunityScore = formContext.getAttribute("new_opportunityscore").getValue();

	if (opportunityScore < 0 \|\| opportunityScore > 100) {
	formContext.getControl("new_opportunityscore").setNotification("Opportunity score must be between 0 and 100.");

	//Prevent save
	executionContext.getEventArgs().preventDefault();
	} else {
	formContext.getControl("new_opportunityscore").clearNotification();
	}
	}

OnSave Event Occurs When

When the user clicks the Save or Refresh button in the command bar, even if there are no changes to be saved.
When the user leaves the form with unsaved data remaining.
Execution of the formContext.data.entity.save method, even when no data has been changed.
Execution of the formContext.data.save method when there’s unsaved data in the form.
Execution of the formContext.data.refresh method with a true value as the first parameter, and unsaved data in the form.
The AutoSave option, set to trigger 30 seconds after unsaved changes are detected in the form.
