         <apex:commandButton value="Select" action="{!closeProduct}"/>
         <apex:commandButton value="Cancel" action="{!Reset}"/>
     </apex:pageBlockButtons>
     <h1>By Keyword</h1>
      <apex:pageBlockSection >
        <apex:inputText value="{!searchstring}"/>

    </apex:pageBlock>

    <apex:pageBlock >


                <apex:pageBlockTable value="{!wrapProductList}" var="accWrap"   >
                    <apex:column >
                      <apex:facet name="header">
                            <apex:inputCheckbox onclick="selectAllCheckboxes(this,'inputId')"/>
                        </apex:facet>
                      <apex:inputCheckbox value="{!accWrap.selected}" id="inputId"/>
                    </apex:column>
                    <apex:column >  
                    <apex:outputlink value="https://ap1.salesforce.com/{!accWrap.pro.id}">{!accWrap.pro.Name}</apex:outputlink>  
                    </apex:column> 
                    <apex:column value="{!accWrap.pro.ProductCode}" />
                    <apex:column value="{!accWrap.pro.Description}" />
                    <apex:column value="{!accWrap.pro.Family}" />
                    <apex:column value="{!accWrap.pro.Type__c}" />

                    </apex:pageBlockTable>


        </apex:pageBlock>
  </apex:form>
</apex:page>

Controller--

public class GEN_ProductSelectionController {


     ID cid = ApexPages.currentPage().getParameters().get('id');

     public PageReference Reset() {
            return null;
     }


     public List<wrapProduct> wrapProductList {get; set;}
     public List<Product2> selectedProducts{get;set;}
     public List<OpportunityLineItem> closeProduct{get;set;}
     public List <Product2> pro {get;set;}  
     public String searchstring {get;set;}  

     public void search(){  
             wrapProductList = new List<wrapProduct>();
             string searchquery='select name,id,ProductCode,Description,Family,Type__c from Product2 where name like \'%'+searchstring+'%\' Limit 20';  

             for(Product2 a: Database.query(searchquery)) {
                  wrapProductList.add(new wrapProduct(a));
             }
     }  

    public GEN_ProductSelectionController(){
             wrapProductList = new List<wrapProduct>();

             for(Product2 a: [select Id, Name,ProductCode,Description,Family,Type__c from Product2]) {
             wrapProductList.add(new wrapProduct(a));
             }
    }

    public class wrapProduct {
            public Product2 pro {get; set;}
            public Boolean selected {get; set;}

            public wrapProduct(Product2 p) {
                pro = p;
                selected = false;
            }
    }

    public PageReference closeProduct() {
            selectedProducts = new List<Product2>();

            for(wrapProduct wrapProductObj : wrapProductList) {

                 if(wrapProductObj.selected == true) {
                  selectedProducts.add(wrapProductObj.pro);
                 }
            }
            PageReference pagePrice = new PageReference('/apex/GEN_MultiEdit?id='+cid);
            pageprice.setRedirect(true);
            return pageprice; 

    }

    public void closeAccou(){
            selectedProducts = new List<Product2>();

            for(wrapProduct wrapProductObj : wrapProductList) {

               if(wrapProductObj.selected == true) {
                   selectedProducts.add(wrapProductObj.pro);
               }
            }
              insert selectedProducts;


    }



}

  • Can you post error messages with line numbers? – powlo Feb 12 '16 at 13:40
  • @powlo there is no error, values are not visible, – RAT__ Feb 12 '16 at 14:24

    @RAT__ Bit confusing. What do you mean move selected checkbox from one row to another VF page? Can just remove unnecessary code and explain what you are trying to do. – Ratan Paul Feb 12 '16 at 14:30
  • @Ratan i have added images, which tells that after selecting products i am trying to click select button which is redirecting to next page which should show these products those are selected – RAT__ Feb 12 '16 at 14:55
  • ignore that title Account Name, that should be Selected products – RAT__ Feb 12 '16 at 14:56

I believe that your issue is that you're setting pageprice.setRedirect(true); in your closeProduct() method.

Setting the redirect to true causes Salesforce to issue a completely new HTTP GET request. This redirect process also flushes the viewstate, which contains the information used to reconstruct the state of your controller.

This means that with setRedirect(true), all your information is lost unless you pass the information through a page parameter (or save it in an sObject and then query for the information in your controller's constructor).

remove pageprice.setRedirect(true);, and your second page should work as you expect.
