if user selects 10 Products and these are associated to 3 different product types, 3 PDF files has to be generated and download in to local system.

Hi I have a requirement please find the below ,

REQ : Create a new Button on Opportunity detail page, once user click on the button need to show the Product records in the vf page with input check box in front of the each record.

Once user selects records and click on save leads to download the PDF document based on Product Type

 

Ex: if user selects 10 Products and these are associated to 3 different product types, 3 PDF files has to be generated and download in to local system.

 

Work around : i have created VF page for  dispalying all products and this VF page  created a button called Save Lead, in this VF page i selected 3 records based on the product type and i click the save lead button ,automatically PDF has to be generated ,only 1 pdf file generated ,but i selected 3 records.

       oppid = System.currentPageReference().getParameters().get('oppid');   

    }

    //This method uses a simple SOQL query to return a List of Product2s

    public List getProducts() {

        if(Product2List == null) {

            Product2List = new List();

            for(Product2 c: [SELECT Id, Family, IsActive, ProductCode, Name FROM Product2 where Id=:oppid AND isactive=true AND ID IN (select product2id from opportunityLineItem where product2id!=null)]) {

                // As each Product2 is processed we create a new ProductWrapper object and add it to the Product2List

                Product2List.add(new ProductWrapper(c));

            if(cCon.selected == true) {

                selectedProduct2s.add(cCon.con);

        pageRef.getParameters().put('recordsize',string.valueof(selectedTypes.size()));

         pageref.setRedirect(false);

    // This is our wrapper/container class. A container class is a class, a data structure, or an abstract data type whose instances are collections of other objects. In this example a wrapper class contains both the standard salesforce object Product2 and a Boolean value

    public class ProductWrapper {

        public Product2 con {get; set;}

        public Boolean selected {get; set;}

        //This is the contructor method. When we create a new ProductWrapper object we pass a Product2 that is set to the con property. We also set the selected value to false
