Hi,

I am trying to display the cases based on option selected by the user. I have two options open incidents and closed incidents. By default it will display open incidents. when user selects closed incidents it should display all the closed incidents. I somehow managed to build this. But the pagination is not working properly. For the datatable to refresh I have seen in other posts, that we should not use if(con==null) --  this will not refresh the table. I have commented that part. The moment I have commented that line in my controller, pagination is not working. Could anyhelp me with this issue. Below is my visaluforce page and the controller :

<apex:page sidebar="false" controller="MyIncidentsPageController">

<script>
    var val;
    function changeCaseType(changedvalue){
        val = changedvalue.value;
        setCaseStatusMethod(val);
    }
</script>
<apex:form >
    <apex:outputPanel >
       <apex:selectRadio value="{!caseType}" onchange="changeCaseType(this)">
           <apex:selectOptions value="{!items}">
           </apex:selectOptions>           
       </apex:selectRadio> 
    </apex:outputPanel>
    <apex:actionFunction action="{!setCaseStatusMethod}" name="setCaseStatusMethod">
    </apex:actionFunction> 
    <apex:outputPanel style="padding:10px;display:block;" id="caseList">
    <apex:dataTable value="{!Cases}" var="OI"  headerClass="header" style="border-style:solid;border-width:2px;border-color:#c8c8c8;" rowClasses="odd,even" width="100%">
        <apex:column headerValue="Incident" style="padding:10px;">  
                <apex:outputText >{!OI.CaseNumber}</apex:outputText>
        </apex:column>
        <apex:column value="{!OI.Created__c}" headerValue="Created" style="padding:10px;color:#2f627f;"/>
        <apex:column value="{!OI.Modified__c}" headerValue="Modified" style="padding:10px;color:#2f627f;"/>
        <apex:column value="{!OI.Priority}" headerValue="Priority" style="padding:10px;color:#2f627f;"/>
        <apex:column value="{!OI.Productweb__c}" headerValue="Product" style="padding:10px;color:#2f627f;"/>
        <apex:column value="{!OI.Submitted_By__c}" headerValue="Submitted By" style="padding:10px;color:#2f627f;"/>
        <apex:column value="{!OI.Subject}" headerValue="Subject" style="padding:10px;color:#2f627f;"/>
        <apex:column value="{!OI.Status}" headerValue="Status" style="padding:10px;color:#2f627f;"/>
    </apex:dataTable>
     <apex:panelGrid columns="3" style="float:right;" id="links">
    <apex:commandLink action="{!previous}" rendered="{!hasPrevious}" style="padding:12px;">Previous</apex:commandlink>
    <apex:outputLabel rendered="{!(hasPrevious && hasNext)}" >|</apex:outputLabel>
    <apex:commandLink action="{!next}" rendered="{!hasNext}" style="padding:12px;">Next</apex:commandlink>
    </apex:panelGrid><br/>
    </apex:outputPanel>
    <apex:outputpanel style="float:right;display:block;margin-right:7px;padding-top:2px;">

    </apex:outputPanel>
       </apex:form>
</apex:page>

Here is my controller

public with sharing class MyIncidentsPageController {
           
    public List<Case> caseList {get;set;}
    String caseType;    
    public String caseStatus {get;set;}
    
    public String getcaseType(){
        return caseType;
    } 
    
    public void setcaseType(String caseType){
        this.caseType = caseType;
    }
    
    public PageReference setCaseStatusMethod(){
        caseStatus = caseType;
        return null;
    }
       
    public MyIncidentsPageController(){
        caseType='Open';
        caseStatus='Open';
    }
    
    public List<SelectOption> getItems(){
        List<SelectOption> options = new List<SelectOption>();
        options.add(new SelectOption('Open','Open Incidents'));
        options.add(new SelectOption('Closed','Closed Incidents'));
        return options;
    }

    public ApexPages.StandardSetController con{
        get{
         // if(con==null){
                con = new ApexPages.StandardSetController(Database.getQueryLocator([select Id,Subject,CaseNumber, Resolution__c,AccountId, Status, Priority,Productweb__c, Created__c,Modified__c,Submitted_By__c,CreatedDate from Case where status=:caseStatus order by CreatedDate desc]));
                con.setPageSize(10);
          //  }
          return con;
        }
        set;
    }
    
    public Boolean hasNext{
        get{
            return con.getHasNext();
        }
        set;
    }
    
    public Boolean hasPrevious {
        get{
            return con.getHasPrevious();
        }
        set;
    }
    
    public void next(){
        con.next();
    }

    public void previous(){
        con.previous();
    }
    
    public List<Case> getCases(){
        caseList = con.getRecords();
        return caseList;    
    }

}

Thanks in advance.
