How can I mass update Account Ownership from a List View?

A great feature for Lightning Experience is support for using Visualforce buttons on list views. With this feature, you can use existing Visualforce actions in Lightning and work with multiple records in lists. Here’s an example of how:

Step 1: Create a Visual Force page – Code below:

<apex:page standardController="Account" recordSetVar="accounts" tabStyle="Account" sidebar="false" lightningStylesheets="true">
    <apex:form >
        <apex:pageBlock title="Edit Accounts" mode="edit">
            <apex:pageMessages />
            <apex:pageblockButtons location="top">
                <apex:commandButton value="Save" action="{!Save}" />
                <apex:commandButton value="Cancel" action="{!cancel}"/>
            </apex:pageBlockButtons>
        <apex:pageBlockTable value="{!selected}" var="A">
            <apex:column headerValue="Name">
                <apex:outputField value="{!A.name}"/>
            </apex:column> 
            <apex:column headerValue="Owner">
                <apex:inputField value="{!A.OwnerId}"/>
            </apex:column>
       </apex:pageBlockTable>         
    </apex:pageBlock>
  </apex:form>
</apex:page>

Step 2. Create a custom button on the Account Object and assign the visual force page to it. Name the custom button “Change Owner”.

Step 3. Add the custom button to the search layout.

GREAT ! Now let’s test!!

From your Accounts select your Accounts you want to change ownership (make sure your List View doesn’t show your recently viewed Accounts).

Visual force will show the below
