Without seeing how you are doing things (and assuming you may be using the same controller) your options would be:

Using a dynamic query in the controller:


1. use `apexPages.currentPage().getURL()` and determine the page
2. Based on the page set the where clause of the query

or

1. Use a URL parameter say 'filterOn' as set it when calling the page:


either way you get the idea from the code below.

    public string filterOn;
    
    public className(){
       filterOn = apexPages.currentPage().getParameters().get('filterOn');
    }
    
    public DATATYPE[] getmyMethod(){
        String qry = 'Select xxx from xxx ';
        if(!string.isBlnak(filterOn)
           try += ' Where FILENAME = :filterOn';
    
        return database.query(try);
    }

**Note** you will get a much better and more direct answer if you post your code :)
