Hi, 

 Visulaforce and Controller which i have created is conditionally SOQL I tried few methods which posted in few blogs but i couldnt sucess.

 In controller I am limiting query to display only 10 records for now. But there are more than 1000k records. Please suggest me how to achive pagination on my requirement. 

Controller

public class Renwal_Account_test
{
  //URL Passing Parameters.
  String PageContractId = ApexPages.currentPage().getParameters().get('ContractId');    
  String PageAccountId  = ApexPages.currentPage().getParameters().get('AccountId');  
 
  //Our collection to class/wrapper objects wrapAsset
  public List<wrapAsset> wrapAssetList {get; set;}
  public List<Asset> selectedAssets{get;set;}    
   
  public Renwal_Account_test()
  { 
   GetAccount = new Asset();    //Get Account Id from Page
   GetContract = new Asset();   //Get Contract Name from Page  
   Filter_Account_Records();
   }
 
  public Asset GetAccount{get;set;}
  public Asset GetContract{get;set;}
   
  public List<Asset> Account_yourObjList{get;set;}
  public List<Asset> Asset_yourObjList{get;set;}  
  public List<Asset> Default_Asset_yourObjList{get;set;} 
  
  //Function to Return Asset Report Passing Account ID   
  public void Filter_Account_Records(){
    Account_yourObjList = new List<Asset>();
   
  If ( GetAccount.AccountId == NULL || GetContract.Name == NULL )
  {
    If ( PageContractId <> NULL )
     {
      Contract C;
      C = [SELECT Name FROM Contract WHERE Id = :PageContractId Limit 1];
      Account_yourObjList = [SELECT Id,AccountId,Product2Id,SerialNumber,last_contract_number__c,Service_Start_Date_Min__c, Service_End_Date_Max__c,InstallDate from Asset WHERE last_contract_number__c = :C.Name LIMIT 10];
