Hi Hemanth,

Please go through with the below example. Hope this helps you write your code.

Visualforce page:

<apex:page controller="thousandLimit">    
   <apex:pageBlock >
      <apex:repeat value="{!thousandBlocks}" var="block">
            <apex:pageBlockTable value="{!block.cases}" var="c">
            <apex:column value="{!c.CaseNumber}"/>
            <apex:column value="{!c.owner.name}"/>
            <apex:column value="{!c.App_Process__c}"/>
            <apex:column value="{!c.Load__c}"/>
            <apex:column value="{!c.subject}"/>
            <apex:column value="{!c.Estimated_Completion_Date__c}"/>   
            <apex:column value="{!c.Complete__c}"/>
            <apex:column value="{!c.Priority}"/>
            <apex:column value="{!c.Case_Age_Days__c}"/>                    
            </apex:pageBlockTable>
        </apex:repeat>
     </apex:pageBlock>  
</apex:page>

Apex Controller:

public class thousandLimit
{
    private limitWrapper[] thousandBlocks = new limitWrapper[]{};
    
    private final integer listLimit;
    
    public thousandLimit()
    {
        listLimit = 1000;
    }
    
    public limitWrapper[] getthousandBlocks()
    {
        thousandBlocks = new limitWrapper[]{};
        
        integer counter = 0;
        integer loopCount = 0;
        case[] tmpcase = new case[]{};
        
        for(case c:[select CaseNumber,owner.name,App_Process__c,Load__c,subject,Estimated_Completion_Date__c,Complete__c,Priority,Case_Age_Days__c from Case
                where (Status != 'Closed' or Status != 'Declined') and Estimated_Completion_Date__c = null and owner.Alias like 'EA%' order by owner.name])
        {
            if(counter < listLimit)
            {
                tmpcase.add(c);
                counter++;
            }
            else
            {
                loopCount++;
                thousandBlocks.add(new limitWrapper(tmpcase,loopCount));
                tmpcase = new case[]{};
                tmpcase.add(c);
                counter = 0;
            }            
        }
        
        if(thousandBlocks.size() == 0)
        {
            loopCount++;
            thousandBlocks.add(new limitWrapper(tmpcase,loopCount));
        }
        
        return thousandBlocks;
    }
    
    public class limitWrapper
    {
        public case [] cases {get;set;}
        public integer blockNumber {get;set;}
        public limitWrapper(case[] accs, integer i)
        {
            cases = accs;
            blockNumber = i;
        }
        
    }
}
