Hello Dear,

Use the following code.
  
public class AccountController1 
{
    public Account accounts{get;set;}
    
    public List<Account> selectedAccountList = new List<Account>();
    private ApexPages.StandardSetController standardController;
    public AccountController1(ApexPages.StandardController controller) {

    }

    public AccountController1(ApexPages.StandardSetController standardController)
    {
        this.standardController = standardController;
        List<Account> selectedAccounts = (List<Account>) standardController.getSelected();
        for(Account selectedAccount : selectedAccounts)
        {
            //if(selectedAccount.ownerid== null) 
            selectedAccount.ownerid = selectedAccount.ownerid;
            //else if(selectedAccount.ownerid == 'Low')
            System.debug('selectownerid>>>'+selectedAccount.ownerid);
           //  System.debug('selectownerid>>>'+selectedAccount.ownerid);
            //    selectedAccount.ownerid = 'Medium';
           /// else if(selectedAccount.ownerid == 'Medium')
            //    selectedAccount.ownerid = 'High';
            selectedAccountList.add(selectedAccount);
        }       
    }

    
    
    public PageReference updateAccount()
    {       
        //update accounts;
        //standardController.save();
        update selectedAccountList;
        return null;
        // Call StandardSetController 'save' method to update (optional, you can use your own DML)
        //return null;   
    }
}

hi mudasir,

it gives a error

System.SObjectException: SObject row was retrieved via SOQL without querying the requested field: Account.OwnerId
Class.AccountController1.<init>: line 18, column 1     
Mudasir WaniMudasir Wani
Hi Prateek,

We are using SObject so this error is not supposed to occur.

Can you paste your SOQL if you are using them in your actual code

I have run the code in my developer org and it is working fine.

Apex Class 
public class AccountController1 
{
    public Account accounts{get;set;}
    
    public List<Account> selectedAccountList = new List<Account>();
    private ApexPages.StandardSetController standardController;
    public AccountController1(ApexPages.StandardController controller) {

    }

    public AccountController1(ApexPages.StandardSetController standardController)
    {
        this.standardController = standardController;
        List<Account> selectedAccounts = (List<Account>) standardController.getSelected();
        for(Account selectedAccount : selectedAccounts)
        {
            //if(selectedAccount.ownerid== null) 
            selectedAccount.ownerid = selectedAccount.ownerid;
            //else if(selectedAccount.ownerid == 'Low')
            System.debug('selectownerid>>>'+selectedAccount.ownerid);
           //  System.debug('selectownerid>>>'+selectedAccount.ownerid);
            //    selectedAccount.ownerid = 'Medium';
           /// else if(selectedAccount.ownerid == 'Medium')
            //    selectedAccount.ownerid = 'High';
            selectedAccountList.add(selectedAccount);
        }       
    }

    
    
    public PageReference updateAccount()
    {       
        //update accounts;
        //standardController.save();
        update selectedAccountList;
        return null;
        // Call StandardSetController 'save' method to update (optional, you can use your own DML)
        //return null;   
    }
}
Visualforce Page 
<apex:page standardController="Account" extensions="AccountController1">
    <apex:form >
        <apex:pageblock >
            <apex:pageblockbuttons >
                <apex:commandButton action="{!updateAccount}" value="Save"/>
            </apex:pageblockbuttons>
            <apex:pageblockSection >
                <apex:inputField value="{!accounts.OwnerId}"/>
            </apex:pageblockSection>
        </apex:pageblock>
    </apex:form>
</apex:page>

Try it in developer org and see if you have any issue.

If you are using same code in some other org and you are getting some error then we need to look into your profile.

Hi Parteek Goyal 3,

Please try below controller. 
public class AccountController1 
{
    public Account accounts{get;set;}
    
    public List<Account> selectedAccountList = new List<Account>();
    private ApexPages.StandardSetController standardController;
    public AccountController1(ApexPages.StandardController controller) {

    }

    public AccountController1(ApexPages.StandardSetController standardController)
    {
		List<String> fieldList = new List<String>();
		fieldList.add('Account.OwnerId');
		standardController.addFields();
        this.standardController = standardController;
        List<Account> selectedAccounts = (List<Account>) standardController.getSelected();
        for(Account selectedAccount : selectedAccounts)
        {
            //if(selectedAccount.ownerid== null) 
            selectedAccount.ownerid = selectedAccount.ownerid;
            //else if(selectedAccount.ownerid == 'Low')
            System.debug('selectownerid>>>'+selectedAccount.ownerid);
           //  System.debug('selectownerid>>>'+selectedAccount.ownerid);
            //    selectedAccount.ownerid = 'Medium';
           /// else if(selectedAccount.ownerid == 'Medium')
            //    selectedAccount.ownerid = 'High';
            selectedAccountList.add(selectedAccount);
        }       
    }

    
    
    public PageReference updateAccount()
    {       
        //update accounts;
        //standardController.save();
        update selectedAccountList;
        return null;
        // Call StandardSetController 'save' method to update (optional, you can use your own DML)
        //return null;   
    }
}

Let us know if it helps.

Hi Prateek,

Sorry My bad, Please try below code. Missed to pass list as parameter. 
public class AccountController1 
{
    public Account accounts{get;set;}
    
    public List<Account> selectedAccountList = new List<Account>();
    private ApexPages.StandardSetController standardController;
    public AccountController1(ApexPages.StandardController controller) {

    }

    public AccountController1(ApexPages.StandardSetController standardController)
    {
		List<String> fieldList = new List<String>();
		fieldList.add('Account.OwnerId');
		standardController.addFields(fieldList);
        this.standardController = standardController;
        List<Account> selectedAccounts = (List<Account>) standardController.getSelected();
        for(Account selectedAccount : selectedAccounts)
        {
            //if(selectedAccount.ownerid== null) 
            selectedAccount.ownerid = selectedAccount.ownerid;
            //else if(selectedAccount.ownerid == 'Low')
            System.debug('selectownerid>>>'+selectedAccount.ownerid);
           //  System.debug('selectownerid>>>'+selectedAccount.ownerid);
            //    selectedAccount.ownerid = 'Medium';
           /// else if(selectedAccount.ownerid == 'Medium')
            //    selectedAccount.ownerid = 'High';
            selectedAccountList.add(selectedAccount);
        }       
    }

    
    
    public PageReference updateAccount()
    {       
        //update accounts;
        //standardController.save();
        update selectedAccountList;
        return null;
        // Call StandardSetController 'save' method to update (optional, you can use your own DML)
        //return null;   
    }
}

Let us know if it works.
