Adding a list of records to Standardsetcontroller records

 

Does anybody have an idea of how to add a list of records to a Standardsetcontroller records.

 

List<Order_c> orderlist1 = this.getordheaderList1();
List<Order_c> orderlist2 =(List<Order__c>)this.totalOrders.getRecords();

orderlist2.addAll(orderlist1);

 

 It is throwing an error as " collection is Read only" while adding the lists.

 Does anybody have an idea how to implement that.

 

 I need to show all the list of records on a vf page.

You can use the following code to get the records for standardsetcontroller - 

 

public ClassConstrc(ApexPages.StandardSetController controller) {
        ApexPages.StandardSetController cntr = (ApexPages.StandardSetController)controller;
        List<order__c> orderList = (List<order__c>)cntr.getRecords();

}

Hi Rajjj,

 

I don't understand why are you trying to add ANOTHER list of Records to StandardSetController's records list, when you want to display ALL the records on the visual force page.

 

I can help you if understand your exact requirement, I have worked several scenarios using Standard Set Controller where I created vf pages with pagination control'

@kamini

 

Here "totalorders" is equal to your "cntr" and i am getting records by using totalorders.getRecords() and then type casting to  (List<order__c>)

 

Like this:

 

List<Order_c> orderlist2 =(List<Order__c>)this.totalOrders.getRecords();

 

@Shah

 

I have 2 order lists. one is direct orderlist and other is indirect orderlist.

 

This line will bring indirect orderlists by querying a different table and then using that list I will query the Order__c. That way I get my indirectoderlist.

 

List<Order_c> orderlist1 = this.getordheaderList1();

 

The second line will directly get orders from order__c. And that list we get through StandardSetController. These orders are direct orders.

 

If a company has both direct and indirect orders then we need to show both.

For that purpose i need to add list to otherlist. If it is normal list I can use addAll function. When I am using on this list I am getting collection is Read-only error.

 

I think we need to use wrapper class. But i havent used them anytime. Can you give me an idea on how to implement my requirement through wrapper class.(I have seen couple of examples but I didn't clearly understood the usage.)

 

 

I hope I have explained clearly.

I can explain you wrapper class easily., before that...

 

why don't you go for a simple solution??

 

      make a SINGLE SOQL query.

 

      i.e.

 

      String qryString = 'select Id,name,field1__c, field2__c,etc from Order__c WHERE Id = null OR typeOfSales__c == \'Direct Sales\' OR typeOfSales__c == \'Indirect Sales\' ';

Public ApexPages.standardSetController TotalSalesSetCon = new ApexPages.StandardSetController(Database.getQueryLocator(qryString));

TotalSalesSetCon.pageSize(20);   //20 records per page;
Integer NoOfRecds = TotalSalesSetCon.getResultSize();   // to test howmany records fetched.

 

 

any further help required..

The business model is different.

For direct orders I can query order__c directly.

For indirect orders I need to query shipto__c(object) and then watever the list i get in shipto__c, I need to query in order__c.

We cannot write in a single query. 

 

If you don't get the scenario, you can say in general whether or not it is possible to add a StandardSetController records type casted to Order__c  and other list of Order__c records.
