Question

IsRowVisible Function

Asked by: xrimson77

I am creating a report that has filtering on one worksheet and on another it has the sums of those filtered columns.  When chosing a filter, it hides rows.  The sums on the other page do not reflect what has been filtered... It still gives the total sum of all the rows.  

I am trying to mimic the behavior of charts.  If a row is removed from a chart's data range, that row of data is no longer displayed on the chart.  This is what I am trying to accomplish with filters.

I tried doing a macro and calling it from the cell....

Public Function SGM_IsRowVisible(oRange As Range)

    If oRange.Cells.Count = 1 Then
        If oRange.Cells.Height > 0 Then
            SGM_IsRowVisible = True
        Else
            SGM_IsRowVisible = False
        End If
    Else
        SGM_IsRowVisible = "#VALUE!"
    End If
End Function

but the cells formula does not update when the cells are hidden/unhidden and I do have auto-update on.

I know another way to do it, but it is too obscure for users of this workbook to use:

using the formula =SUBTOTAL(3,C4) will return a 1 if the cell is visible and 0 if it is not.

I would like to avoid using macros to update the cells each time a filter is applied.  But using a macro as a custom formula is OK

Does anyone know either 1) How I can get my custom funtion to properly refresh when rows are hidden/unhidden or 2) A formula that makes sense to the user that they can use?

Thanks!

Hi xrimson77,

Try making   Application.Volatile   the first line in your function.  This will get it to work, but could cause a lot of unnecessary recalculations.  

You could also keep your function the same, but in the cell that calls it, add a predefined function that will calculate.
i.e. instead of
=if(SGM_IsRowVisible(A1),......

use

=if(and(true,SGM_IsRowVisible(A1)),...


Application.Volatile should definately work but as I said it could cause unnecessary calculations.  The second option should do the trick.

Hope this helps!
Matt

Thanks for you help Matt.

I originally needed the function for filters.  I was doing a test case with just hiding a row manually myself.  This is where I am having problems.  In the case with the filters, having the simple =SGM_IsRowVisble(A1) is fine... it get's updated when the filters are changed.  Unfortunately, when I try hiding the row myself, the formula does not get updated.  It only gets updated by using Volatile when other formulas are updated and no other formulas are getting updated when I hide a row.

Any other ideas?  If it's not possible, I can always just rename my function to IsFilterRowVisble.  But I would like to have a robust function that can tell if any row is visible or not and get's updated even when the user manually hides the row.

Thanks again!

What about adding a workbook_sheetselectionchange event to your ThisWorkbook object of your VBAProject that forces calculation?  Like:

Private Sub Workbook_SheetSelectionChange(ByVal Sh As Object, ByVal Target As Range)
    Calculate
End Sub

That way anytime the user changes their selection (whether to click on a cell or hide a row) it forces calculation.

Just a thought
Matt

Looks like the powers above are happy with just having the function renamed to IsFilterRowVisible and having it work only for filtered data.

Thanks Matt!!

No problem, I just wish I had been able to help you! Did you try the sheetselectionchange event? Thanks for the grade either way!

No, I didn't try it, but that would of worked too.  My company tries to stay away from macros in the customer report.  Eventually we will move to AddIns.

Thanks again!
