I want to achieve pagination on a visualforce page with the help of custom controller,right now my code is not working as expected. Can anyone please help me in what I am doing wrong?

My code is as follows:

<apex:page controller="AccountSearchClass">
<apex:form >
    <apex:inputText value="{!searchVariable}" />
    <apex:commandButton action="{!search}" value="Search" reRender="rr"/>
    <apex:pageBlock id="rr">
        <apex:pageBlockTable value="{!accObj}" var="b"  >
            <apex:column value="{!b.Name}" />
            <apex:column value="{!b.Phone}" />
            <apex:column value="{!b.AccountNumber}" />        
        </apex:pageBlockTable>
    </apex:pageBlock>
    <apex:commandButton action="{!search}" value="Search" reRender="rr"/>
    <apex:commandButton value="First Page" rerender="rr" action="{!FirstPage}" disabled="{!prev}"/>
    <apex:commandButton value="Previous" rerender="rr" action="{!previous}" disabled="{!prev}"/>
    <apex:commandButton value="Next" rerender="rr" action="{!next}" disabled="{!nxt}"/>
</apex:form>

Custom controller:

public with sharing class AccountSearchClass {
public String searchVariable { get; set; }
public Integer OffsetSize=0;
public Integer LimitSize=5;
public Integer Totalrec=0;
private String temp;
public List <Account> accObj {get; set;}
public void search() {
    temp = 'Select id ,Name,AccountNumber,Phone from Account WHERE Name Like \'%'+searchVariable+'%\' OR Phone Like \'%'+searchVariable+'%\' ';
    accObj = database.query(temp);
    Totalrec=accObj.size();
}
public void FirstPage()
{
    OffsetSize = 0;
}
public void previous()
{
    OffsetSize =  LimitSize-OffsetSize;
}
public void next()
{
    OffsetSize = OffsetSize + LimitSize;
}
public boolean getprev()
{
    if(OffsetSize == 0)
        return true;
    else
        return false;
}
public boolean getnxt()
{
    if((OffsetSize + LimitSize) > Totalrec)
        return true;
    else
        return false;
}  
  • What exactly is not working? – sfdcFanBoy Jun 14 '16 at 4:40
  • the next button is not showing up when i preview the page – Shobhit Saxena Jun 14 '16 at 4:46
  • Also all the records are getting displayed at the first page only. – Shobhit Saxena Jun 14 '16 at 4:53
  • yes that's because you didn't use offset and limit in your query. I added an answer. – sfdcFanBoy Jun 14 '16 at 4:57

There are quite a lot of missing things in your code

  1. Add search(); at the end of each of these 3 methods : FirstPage(), Next(), Previous()
  2. Your temp query is missing OFFSET AND LIMITat the end of the query. Add it correctly using the variables OffsetSize and LimitSize (LIMIT LimitSize OFFSET OffsetSize)
  3. All your apex:command buttons should be within the pageblock! So, end your <apex:pageblock> after the commandbuttons.

Follow the Example in this link.

Update your code accordingly. It should work.

  • that's ok, No problem! – sfdcFanBoy Jun 14 '16 at 5:25
