Copy the content one IEnumerable to another after checking the index of each record

I want to copy the record from one IEnumerable to another after checking the index of the record. pvm consists of set of records with n number of columns and m number of rows. In view_filter method i am checking index. If the condition holds good I want to copy record to _invMstrSrchResults. Index gets checked one by one.

        public PagingViewModel(IEnumerable<InventoryMasterItem> pvm)
        {            
            ViewList = new CollectionViewSource();
            ViewList.Source = pvm;
            ViewList.Filter += new FilterEventHandler(view_Filter);

            CurrentPageIndex = 0;
            itemcount = 100;
            CalculateTotalPages();            
        }

        private IEnumerable<InventoryMasterItem> _invMstrSrchResults;

        void view_Filter(object sender, FilterEventArgs e)
        {
            int index = ((InventoryMasterItem)e.Item).indexNo - 1;
            if (index >= itemPerPage * CurrentPageIndex && index < itemPerPage * (CurrentPageIndex + 1))
            {
                 // I want to copy record from pvm to _invMstrSrchResults here
                 e.Accepted = true;               
            }
            else
            {
                e.Accepted = false;
            }
        }

FilterEventArgs should be holding an InventoryMasterItem object which you can retrieve in view_Filter. Additionally, you may need to a create a different collection temporarily, List<InventoryMasterItem> and then cast it to an IEnumerable<InventoryMasterItem>:

InventoryMasterItem item = e.Item as InventoryMasterItem;
var list = new List<InventoryMasterItem>();
list.Add(item);
_invMstrSrchResults = list.AsEnumerable();
