• Let us see OFFSET Pagination first:
• Visualforce:

<apex:web page controller= “OffsetPaginationController”>
<apex:kind>
<apex:pageSection id = “ps” title= “accountNumber”>
<apex:pageSectionTable worth = “{!accountNumber}” var = “c” id = “pst”>
<apex:column worth = “{!c.userName}” />
<apex:column worth = “{!c.userContact}” />
</apex:pageSectionTable>
<apex:commandClick worth = “firstButton” motion = “{!frstbtn}” disabled= “{!prev}” reRender = “pd, pb”/>
<apex.commandClick balue = “prevButton” motion = “{!prevbtn}” disabled = “{!prev}” reRender = “pt, pb” />
<apex.commandClick worth = “nextButton” motion = “{!nxtbtn}” disabled = “{!nxt}” reRender = “pt, pb” />
<apex.commandClick worth = “endButton” motion = “{!endbtn}” disabled = “{!nxt}” reRender = “pt, pb” />
</apex:pageSection>
</apex:kind>
</apex:web page>

Controller:

public class OffsetPaginationController{
public List<accountNumber> 1staccountNumber;
public Integer wholeRecordsCount (get;set;)
public Integer sizeOffset = 0;
public Integer limitOfQuery = 10;
public OffsetPaginationController(){
1staccountNumber = new List<accountNumber>();
wholeRecordsCount = [SELECT count() FROM accountNumber];
}
public List<accountNumber> getaccountNumbers(){
1staccountNumber = [SELECT Id, userName, Contact FROM userContact ORDER BY userName LIMIT: QueryLimit OFFSET: sizeOffset];
return 1staccountNumber;
}
public Boolean getprev(){
if(sizeOffset > 0)
return false;
else
return true;
}
public Boolean getnext(){
if(sizeOffset + questionLimit < wholeRecordsCount)
return false;
else
return true;
}
public PageReference  nxtbtn(){
sizeOffset += questionLimit;
return null;
}
public PageReference prevbtn(){
sizeOffset -= questionLimit;
return null;
}
public PageReference frstbtn(){
sizeOffset = 0;
return null;
}
public PageReference endbtn(){
sizeOffset = wholeRecordsCount – math.mod(wholeRecordsCount, questionLimit);
return null;
}
}

• Let us now see the StandardSetcontroller Pagination

Visualforce:

<apex:web page controller= “OffsetPaginationController”>
<apex:kind>
<apex:pageSection id = “ps” title= “accountNumber”>
<apex:pageSectionTable worth = “{!accountNumber}” var = “c” id = “pst”>
<apex:column worth = “{!c.userName}” />
<apex:column worth = “{!c.userContact}” />
</apex:pageSectionTable>
<apex:commandClick worth = “firstButton” motion = “{!ssc.frstbtn}” disabled= “{!!ssc.hasprev}” reRender = “pd, pb”/>
<apex.commandClick balue = “prevButton” motion = “{!ssc.prevbtn}” disabled = “{!!ssc.hasprev}” reRender = “pt, pb” />
<apex.commandClick worth = “nextButton” motion = “{!ssc.nxtbtn}” disabled = “{!!ssc.hasnxt}” reRender = “pt, pb” />
<apex.commandClick worth = “endButton” motion = “{!ssc.endbtn}” disabled = “{!!ssc.hasnxt}” reRender = “pt, pb” />
</apex:pageSection>
</apex:kind>
</apex:web page>

Controller:

public class OffsetPaginationController{
public List<accountNumber> 1staccountNumber;
public Integer wholeRecordsCount (get;set;)
public OffsetPaginationController(){
1staccountNumber = new List<accountNumber>();
measurement = 10;
}
public ApexPages.StandardSetController ssc{
get{
if(ssc == null){
String resultOfQuery = ‘SELECT Id, userName, userContact from Contact ORDER BY Name’;
ssc = new ApexPages.StandardSetController(Database.getQueryLocator(resultOfQuery));
ssc.setPageSize(measurement);
wholeRecordsCount = ssc.getResultSize();
