Hi,

You have wrongly define the lists in teh controllers.

Find teh controller and VF Page below.

*********************************************************************************************************

public class TestPageController {
public Account acc {get;set;}

public List<Contactwrapper> conlist{get;set;}
public List<Contact> con{get;set;}

// Public Contact inList{get;set;}
// Public List l{get;set;}
// List conlist;

public TestPageController()
{
acc=new Account();
conList= new List<Contactwrapper>();
}
public PageReference getContacts() {
con= [select id, firstname, LastName,Birthdate,Phone from Contact where Accountid =: acc.parentid];
system.debug('#########'+con);
conlist = new List<Contactwrapper>();
for(Contact c: con)
{
conlist.add(new Contactwrapper(c,false));
}
system.debug('#########'+conlist);
return null;

}
public PageReference getSelected()
{
// conlist.clear();
for(Contactwrapper awp: conlist)
if(awp.selected == true)
{
// conlist.add(accwrapper.acc);
system.debug('********'+awp.cw.firstname);

}
return null;
}

public pageReference getDelete(){
List<Contact> dList = new List<Contact>();
for(Contactwrapper wrap: conlist){
if(wrap.selected == true)
{
dList.add(wrap.cw);
}
}
if(dList !=null && dList.size() >0){
delete dList;
}
return null;
}

public void getCancel(){

}

public PageReference AddRow() {
Contact conObj = new Contact();
conlist.add(new Contactwrapper(conObj,false));
return null;
}
public pageReference SaveRecord(){
List<Contact> ctList = new List<Contact>();
for(Contactwrapper wrap: conlist){
if(wrap.selected == true)
{
wrap.cw.AccountId = acc.parentid;
ctList.add(wrap.cw);
}
}
if(ctList!=null && ctList.size() >0){
upsert ctList;
}
return null;
}

public class Contactwrapper{
public Contact cw{get; set;}
public Boolean selected{get; set;}

public Contactwrapper(Contact c,boolean b){
cw = c;
selected = b;
// system.debug('********'+acc);
}
}
}
