Changing Values on Edit

Client-side business rules allow changing the value of a field without having to save it to the database. This way, the user can either approve the value, change it, or leave the original data intact.

Let’s add 7 days to the Order Date of an order when a user starts editing.

Start the Project Designer. In the Project Explorer, switch to the Controllers tab. Right-click on Orders / Business Rules node, and press New Business Rule.

Creating a new business rule for Orders controller.

Assign the following values:

Property Value
Type JavaScript
Command Name Edit
Phase After
Script
var d = [OrderDate];
if (this.dataView().get_isEditing() && d != null) {
    d.setDate(d.getUTCDate() + 7);
    d.setHours(0);
    [OrderDate] = d;
}

The business rule will get the current date value of OrderDate, add 7 days, and assign the value.

Press OK to save. On the toolbar, press Browse. Navigate to the Orders page. Note the Order Date of a specific record.

Highlighting an order record and noting the Order Date.

Start editing the the record. The Order Date will be moved forward by 7 days from the original value.

When the order is edited, the Order Date is moved forward by 7 days.

If the user presses Cancel at this time, the Order Date will not be changed. If the user saves the record, the new value will be applied.
