Get a number from a custom setting and display it on the visualforce page.

Question

I have a custom setting with one profile assigned to it and that's Heathrow portal. It has a field called Largest Number and a value assigned to it. I need to display that number on a visualforce page using apex class. My method doesn't seem to be working.
On the top of the visualforce page I assigned the page to the custom setting

**<apex:page sidebar="false" standardStylesheets="false" controller="GenerateNumber"  showHeader="false" title="Contact us">

and that seems to be fine but when I try to write a method that just returns the number it's failing and giving me a lot of errors.

public class GenerateNumber {

     public String numbersgenerated {get;set;}
     public String userinput {get;set;}

public GenerateNumber(){}



     public PageReference getNumbers() {
        return [SELECT Largest_Number__c FROM Number_Setting__c];
    }

Answer 1

try simple approach. Declare a public variable

public Decimal largenum {get;set;}


and in the method assign value

list<Number_Setting__c> cslist = [SELECT Largest_Number__c FROM Number_Setting__c];

if(cslist.size() >0)
largeNum = cslist[0].Largest_Number__c;

and use it in the VF page.
