Hi

I have a Custom Page which is based on Contact Object. Now I need to display Views which are on Standard Contact Pageon Custom VF Page . I should also be able to Edit and Create new Views just like in  Standard page Process. The problem is If I use Standard Controller= "Contact" and Extensions= "Custom_Pagination" I get an error on StandardsetController in apex code. Kindly help me in this plssss

VF Page:

<apex:page controller="Custom_Pagination">
<style type="text/css">
.loadingIcon {
background-image: url(/img/loading.gif);
width: 16px;
height: 16px;
}

</style>
<script type="text/javascript">
function checkClicked(){
var isChecked = false;
var inputElem = document.getElementsByTagName("input");
for(var i=0; i<inputElem.length; i++){
if(inputElem[i].checked){
isChecked = true;
}
}
if(isChecked){callMe();}
else{
alert('Please select at least one Contact');
return false;
}
}
function checkAll(cb,cbid)
{
var inputElem = document.getElementsByTagName("input");
for(var i=0; i<inputElem.length; i++)
{

if(inputElem[i].id.indexOf(cbid)!=-1){
inputElem[i].checked = cb.checked;
}
}
}
function highlight (word) {
//alert('1');
document.getElementById (word.id).style.backgroundColor="#8DEEEE"
// alert('1');
}
function dehighlight (word) {
//alert('1');
document.getElementById (word.id).style.backgroundColor="#FFFFFF"
// alert('1');
}
