Updating model object list after sorting

[HM]

I am using ObjectListView.
OLV does a wonderful work when sorting and updating the view object, however i would also like the model object list to be updated based on the sorting.
Any hints will be appreciated.
Thanks.

Grouping makes this a little bit difficult. When the list was grouped, how would the model object list be arranged?

For you want exact display order, you'll have to use GetNthItemInDisplayOrder()

for (int i = 0; i < olv.GetItemCount(); i++) {
    OLVListItem olvi = olv.GetNthItemInDisplayOrder(i);
    if (olvi != null)
        DoSomething(olvi.RowObject);
}
