Use Wrapper Class to show data on the Visualforce Page Using Controller

Arun Garg   5/27/2017   Comment  

1. I am displaying accounts record which have rating not equals to NULL.
2. To show data on page , I create wrapper class and defines three properties and assign account field values in to these properties.
3. I create a method to get day name from account createddate and assign in to wrapper class property by passing parameter createddate of account.

Visualforce Page:

<apex:page controller="UseWrapperCtr" sidebar="false" showHeader="false">

  <apex:pageBlock>

      <apex:pageBlockTable value="{!lstAccWrapper}" var="acc">

          <apex:column headerValue="Account Name" value="{!acc.accName}"/>

          <apex:column headerValue="Rating" value="{!acc.ratingName}"/>

          <apex:column headerValue="Day Name" value="{!acc.dayName}"/>

      </apex:pageBlockTable>

  </apex:pageBlock>

</apex:page>

Apex Class:

public class UseWrapperCtr

{

    public List<Wrapper> lstAccWrapper{get;set;}   // Use this wrapper to show data on the page.

    public UseWrapperCtr()

    {

        lstAccWrapper=new List<Wrapper>();

        List<Account> accounts=[Select Id,name,rating,createddate from Account where rating!=null];

        

        //Iterate account and assign value in wrapper.

        for(Account a:accounts)

        {

           Wrapper w=new Wrapper();

           w.accName=a.Name;

           w.ratingName=a.rating;

           w.dayName=returnDayName(a.createddate);

           lstAccWrapper.add(w);

        }

    }

    

    // Create wrapper class

    public class Wrapper

    {

        public String accName{get;set;}

        public String ratingName{get;set;}

        public String dayName{get;set;}

    }

    

    // Find the day name by providing date.

    public String returnDayName(DateTime accCreateDate)

    {

        String dayName=accCreateDate.format('EEEE'); // get the day name by created date of account.

        return dayName;

    }

}
