Apex Code:

{

     public w var {get;set}

//wrapper class

    public class w

    {

        public String str;

    }

thanks for your reply but i have already done this

 

global with sharing class DashPortalController{
public static List<CaseFailBean> listCaseFailBean{get;set;}

@RemoteAction
global static CaseFailBean[] loadCustomerServiceSuccessRate(String dateFrom){
listCaseFailBean= new List<CaseFailBean>();
CaseFailBean beanObj=new CaseFailBean(AccId,WasteColl,DaysColl,ServiceSuccessRate,ServiceFailureRate);
listCaseFailBean.add(beanObj);
}
global class CaseFailBean{
public String AccName{get;set;}
public String WasteName{get;set;}
public String DaysTotal{get;set;}
public Decimal totalCases{get;set;}
public Decimal totalServiceColl{get;set;}

public CaseFailBean(String Name,String WasteType,String TotalDays,Decimal ServiceSuccessRate,Decimal ServiceFailureRate){
this.AccName= Name;
this.WasteName= WasteType;
this.DaysTotal= TotalDays;
this.totalServiceColl=ServiceSuccessRate;
this.totalCases=ServiceFailureRate;
}

public CaseFailBean(){

}

}

==========================VisualForce Page====================
<apex:page controller="DashPortalController" readonly="true" contentType="application/vnd.ms-excel" language="en-US">
<apex:pageBlock >
<apex:pageBlockTable value="{!listCaseFailBean}" var="bl">
<apex:column headerValue="Account Name">
<apex:outputText value="{!bl.AccName}"/>
</apex:column>
<apex:column headerValue="Waste Name">
<apex:outputText value="{!bl.WasteName}"/>
</apex:column>
<apex:column headerValue="DaysTotal">
<apex:outputText value="{!bl.DaysTotal}"/>
</apex:column>
</apex:pageBlockTable>
</apex:pageBlock>
</apex:page>

 

 

the problem is, in VF page when i click export to csv then CSV file only shows Header name that i have used in 

<apex:column headerValue="">

but not showing the values

Dont use pageblock and other tags for export.... Thats y u r getting the error... think so... My suggestion is try without using tags

it is not showing the values but displays the header

like     Account Name                  Waste Type

Hi

 

Your list listCaseFailBean is empty,because you have not call method loadCustomerServiceSuccessRate(String dateFrom).

Or you can simply create list in  the constructor of mail class as shown below

 

global with sharing class DashPortalController

{
public static List<CaseFailBean> listCaseFailBean{get;set;}

public DashPortalController()

{

CaseFailBean beanObj=new CaseFailBean("some","WasteColl","DaysColl",0,0);
listCaseFailBean.add(beanObj);
}

 

}

 

Try it and let me know whether it works or not??

Thanks

Anil

i have declared CaseFailBean beanObj in @remoteaction, how can i call it in constructor  DashPortalController()

public DashPortalController()

{

}

 

 

Anil MeghnathiAnil Meghnathi

IF you dont need Remoteaction than use constructor otherwise call the  loadCustomerServiceSuccessRate(String dateFrom) from constructor.Try it.and let me know

 

global with sharing class DashPortalController

{
public static List<CaseFailBean> listCaseFailBean{get;set;}

public DashPortalController()

{

 loadCustomerServiceSuccessRate(anyData);
}

@RemoteAction

global static CaseFailBean[] loadCustomerServiceSuccessRate(String dateFrom){
listCaseFailBean= new List<CaseFailBean>();
CaseFailBean beanObj=new CaseFailBean("AccId","WasteColl","DaysColl",ServiceSuccessRate,ServiceFailureRate);
listCaseFailBean.add(beanObj);
}

}
