Simple Pagination

Pagination - To traverse back and forth.

We have used a simple standard apex class controller, an Extension and visualforce page to achieve this task. Below is Output of the code.

Explanation - The constructor in the apex class always sets the page size to 2. You can try increasing the values for viewing more records.

Apex Class

public with sharing class PageDataClass {

    public PageDataClass(ApexPages.StandardSetController controller) {
        controller.setpagesize(2);
    }

}

Explanation - The actions of the commandLinks work even though when there are no methods written in our extension class, wondering why ? These actions are performed by default when a standard controller is in use. (ex: save ...)

Visualforce Page

<apex:page sidebar="false" standardController="MybookSubs__c" recordSetVar="records" 
  extensions="PageDataClass">
  <apex:form >
      <apex:pageBlock >
          <apex:pageBlockSection >
              <apex:pageBlockTable value="{!records}" var="r">
                  <apex:column headerValue="Name">
                      {!r.Name}
                  </apex:column>
             
              <apex:column headerValue="Author">
                      {!r.Author__c}
                  </apex:column>
              </apex:pageBlockTable>
          </apex:pageBlockSection>
          <apex:commandLink value="previous" action="{!previous}"/> | &nbsp;
          <apex:commandLink value="next" action="{!next}"/>
         
      </apex:pageBlock>
  </apex:form>
</apex:page>
