meaning of values returned by GetIntersectedFilteredInRows

    What exactly are the int values that GetIntersectedFilteredInRows returns? View row indeces, model row indeces, data source row indeces, or something else?


    They appear to change depending on how columns are sorted, but then converting them via GetModelRowFromViewRow still leads to inconsistent results.

    P.S.  If I also call GetFilteredOutRowList, I find that sometimes the row numbers that it returns are also contained in the returned values from GetIntersectedFilteredInRows.  How can that be?

    Hi,

    The indexes returned by GetIntersectedFilteredInRows are model row indexes.  You can convert them to view row indexes with GetViewRowFromModelRow if you need to pass the row index into a SheetView method, or use them directly to pass into one of the sheet models (in SheetView.Models), except for the Selection model, which always uses view indexes.

    OK, thanks.  But if they are model row indexes, why are the values returned by GetIntersectedFilteredInRows different before and after a sort, which I would only expect to affect the view row indexes?  For example, a first call to GetIntersectedFilteredInRows returns 2,4,5,3.  Then I click the sort icon on a column, so that I see the same 4 rows in a slightly different order, call GetIntersectedFilteredInRows again, and get 2,3,1,0 this time. 


    Also, how is it that a call to GetIntersectedFilteredInRows immediately followed by a call to GetFilteredOutRowList returns sets of indexes, some of which are contained in both lists?  In other words, how can a row be both filtered in and filtered out?


    So far, the only way I've been able to programmatically determine which rows are filtered in or out is by using IsRowFilteredOut like this:


    for (int i = 0; i < activeSheet.RowCount; i++)


    {


        if (activeSheet.RowFilter.IsRowFilteredOut(activeSheet.GetViewRowFromModelRow(i)))


         ...


    which is also counterintuitive, since I would have thought 'i' was already indexing through view rows rather than model rows.  Perhaps you can help clear up my confusion.

    Hi,

    I'm sorry, I was mistaken; it is returning the view row indexes.  When I translate the row indexes returned by GetIntersectedFilteredInRows using GetModelRowFromViewRow, it returns a consistent list for a given set of filtered rows, regardless of the sort state.

    It is GetFilteredOutRowList that returns model rows.  When I put the model row index for each row in a column, GetFilteredOutRowList returns a list missing the same model row indexes (in a different order, but the same indexes missing) regardless of the sort state.

    Sorry for the confusion!

    OK, thanks for the clarification.  Now I can see that GetIntersectedFilteredInRows is indeed returning view rows, apparently sorted in order of their corresponding model row.
