Controls (Client API reference)
A control represents an HTML element present on the form. Some controls are bound to a specific column, whereas others might represent unbound controls such as an IFRAME, web resource, or a subgrid added to the form.
The control object provides methods to change the presentation or behavior of a control and identify the corresponding column. You access controls using one of the following collections:
- formContext.ui.controls
- formContext.ui Section.controls
- formContext.data.entity Attribute.controls
The formContext.getControl method is a shortcut method to access formContext.ui.controls.get.
Controls are categorized by type. You can determine the type of a control by using the getControlType method. Certain control methods are only available for specific types of controls.
This article provides information about the methods available per control type.

Tip
If you want to modify all the controls bound to a column on a form, use the controls collection inside the column type. For example, to add notification to each control bound to the name column, you can do the following:
const notification = { messages: ['Sample Notification on Name Controls'], notificationLevel: 'RECOMMENDATION', uniqueId: 'my_unique_id'};
formContext.getAttribute("name").controls.forEach(control => control.addNotification(notification));
