Custom Button to call a lightning component

Innovalleyworks - Custom Button to call a lightning component

In this blog you will learn How to create a custom button and add the custom button on the record page in Lightning Experience in Salesforce.

Generally when we talk about the custom button you will find it similar to the concepts of buttons that we use in the Classic Salesforce.
Similar is the way to create a custom button to work in Lightning Experience in Salesforce.

The custom buttons do not exist in Lightning Experience in Salesforce, instead we use Lightning Action to accomplish the work of the custom buttons.

You cannot call lightning components from Button or Link. Instead you can create an Action and can be added to the “Salesforce Mobile and Lightning Experience Actions” section in the page layout.
Also make sure to include force:lightningQuickAction interface to the lightning component

You can call a lightning app on click of a Detail Page Button and embed your lightning component in the lightning app.
Try using something like below in the Button or Link URL value

/c/lighteningComponentApp.app?recid={!record.Id}

Here recid is the attribute of the lightning app – lighteningComponentApp , which will hold the record Id.

Alternatively, you can call a visualforce page on a click of a button and embed your lightning component in the visualforce page

Prerequisites required for adding the button on the record page in Lightning Experience in Salesforce

Write the following code in lightning component:

    1. force:lightningQuickAction

force:lightningQuickAction interface to a Lightning component to allow it to be used as a custom action in Lightning Experience or the Salesforce mobile app.
You can use these components as object-specific or global actions in both Lightning Experience and the Salesforce mobile app.

When used as actions, components that implement theforce:lightningQuickAction interface display in a panel with standard action controls, such as a Cancel button.
These components can display and implement their own controls in the body of the panel, but can’t affect the standard controls. They should nevertheless be prepared to handle events from the standard controls.
If you implement force:lightningQuickAction, you can’t implement force:lightningQuickActionWithoutHeader within the same component.

  1. With Default Headers <!– CustomActionWithHeaders.cmp –>
                       <aura:component implements ="force:lightningQuickAction">
                          <div >
                       		 Hello Welcome to the lightning custom action button with the default headers
                       	  </div >
                       </aura:component >

1.force:lightningQuickActionWithoutHeader

In order to implement both header and footer we need to use force:lightningQuickActionWithoutHeader interface.

The force:lightningQuickActionWithoutHeader interface to a Lightning component to allow it to be used as a custom action in Lightning Experience or the Salesforce mobile app.
You can use these components as object-specific or global actions in both Lightning Experience and the Salesforce mobile app.

When used as actions, components that implement the force:lightningQuickActionWithoutHeader interface display in a panel without additional controls.
The component should provide a complete user interface for the action.
If you implement force:lightningQuickActionWithoutHeader, you can’t implement force:lightningQuickAction within the same component.

2.Without Default Headers <!– CustomActionWithoutHeaders.cmp — >

                           <aura:component implements ="force:lightningQuickActionWithoutHeader" >
                                <div >
                               	 Hello Welcome to the lightning custom action button without the default headers
                                </div >
                           </aura:component >
