VF Sorting

I have the following code and visualforce. I wanted to give users the ability to click on the column headers to allow them to sort the table. Is this possible? I've seen a few things online, but was unable to get it to work with pagination. 

Apex: 
  
public with sharing class Pagination_min {

    Public Integer noOfRecords{get; set;}
    Public Integer size{get;set;}
    public ApexPages.StandardSetController setCon {
        get{
            if(setCon == null){
                size = 500;
                string OwnersId =  userinfo.getUserId() ;
                string Rectypeid =   '01240000000Uexl';
                string Rectypeid2 = '01240000000cnJS';
                string queryString = 'Select Name, StageName,FED__c,Broker__c,Broker_Name__c,Core_Product__c,LeadSource,Number_Quoted__c,CreatedDate FROM Opportunity Where OwnerId = :OwnersId AND IsClosed = False AND (RecordTypeId = :Rectypeid OR RecordTypeId= :RecTypeId2) order by Probability,FED__c asc';
                setCon = new ApexPages.StandardSetController(Database.getQueryLocator(queryString));
                setCon.setPageSize(size);
                noOfRecords = setCon.getResultSize();
            }
            return setCon;
        }set;
    }
     
    Public List<Opportunity> getOpps(){
        List<Opportunity> oppList = new List<Opportunity>();
        for(Opportunity o : (List<Opportunity>)setCon.getRecords())
            oppList.add(o);
        return oppList;
    }
     
    public pageReference refresh() {
        setCon = null;
        getOpps();
        setCon.setPageNumber(1);
        return null; 
    }
    
    
    
   }

Hi,

With pagination, you have to re-run the SOQL query with the appropriate ordering (the data of the other pages are unknown by the client by definition).
  • bobbuzzard.blogspot.com: Sorting Visualforce Tables with JavaScript This will only sort the rows displayed on the page. If this page displayed a subset of rows in a collection, the sorted values wouldn’t reflect the full dataset. In this scenario I’d re-run the SOQL query with the appropriate ordering or sort the collection of data server side.

  • Here is a very simple example of how you could implement sorting using some visualforce and apex. The trick here is an apex:facet tag

Thanks this was helpful. I was able to test and build with the sorting feature. However, now I'm struggling to include the previous,next,refresh, first page, last page info in the bottom of the table. I can't seem to adapt the code from my original post  to the new code that allows for sorting. Is there a way to make the sorting and the page references work below?

Apex with Sorting: 

public class myClass{
    
    
    
    public String sortField {get;set;}
    public String myOrder {get;set;}
    public myClass(){
        // Default setting for the sorting
        sortField = 'Probability';
        sortfield='FED__c';
        myOrder = 'ASC';
    }

    public List<Opportunity> getOpportunities(){
     
      string OwnersId =  userinfo.getUserId() ;
      string Rectypeid =   '01240000000Uexl';
      string Rectypeid2 = '01240000000cnJS';
        String q = 'Select Name,StageName,FED__c,Broker__c,Broker_Name__c,Core_Product__c,LeadSource,Number_Quoted__c,CreatedDate From Opportunity Where OwnerId = :OwnersId AND isClosed=False AND (RecordTypeId = :Rectypeid OR RecordTypeId= :RecTypeId2)';
        q += ' Order by ' +  String.escapeSingleQuotes(sortField) + ' ' + myOrder + ' LIMIT 500';
        return Database.query(q);
    }
}
