Disabling other slicers in excel when slicer is pressed

Question

I have three slicers operating on a pivot table and pivot chart in excel. However, the filters placed from the two other slicers has to be cleared, when one of the slicers is pressed, assuring that only one slicer is operating at the same time. I think this has to be solved using VBA, listening for a click then executing code, other than that I have no idea as I have never worked with Excel or VBA before. Anyone got any suggestions on how I would do this?

Answer 1

Working out what Slicer got clicked is very tricky indeed, because the only application event that gets raised by clicking on a slicer is the PivotTable_Update event. This event tells us which PivotTable the slicer is connected to, but not which field in that PivotTable got filtered. So if you have multiple silcers connected to a PivotTable, you can't tell which one was just clicked on.

I came up with a very convoluted workaround that I posted at http://dailydoseofexcel.com/archives/2014/07/10/what-caused-that-pivottableupdate-episode-iv/ that will get you part the way there: it will tell you which field in a PivotTable just got updated, and then you just need to iterate through all the slicers connected to that PivotTable and clear them if they don't have the same sourcename.

I'll see if I can code something up in due course, but I'm pretty busy at present so I can't promise a fast resolution.

Note that you can assign a macro directly to a slicer that gets triggered when a user clicks on it, and from that you can determine which slicer it is. But unfortunately that macro interferes with the slicer itself: a user can no longer actually operate the slicer to actually change anything.

---UPDATE--- Here's some code that does what you want. There's a lot of different modules here, because the routine code calls quite a few other generic routines I use. And at it's heart is a routine that works out which particular field of a PivotTable gets updated, and that doesn't care if multilpe fields are filtered.

You call it with this event handler, which goes in the ThisWorkbook module for the book in the Visual Basic Editor:

Private Sub Workbook_SheetPivotTableUpdate(ByVal Sh As Object, ByVal Target As PivotTable)
Slicers_OneSlicerOnly Target
End Sub

And that calls these other functions in turn. You don't have to amend anything, and this works on any PivotTables or Slicers you add to this workbook.

Dim slr As Slicer

If sField <> "" Then
    For Each slr In target.Slicers
        sSlicer = slr.SlicerCache.SourceName
        If sSlicer <> sField Then
            If Not target.PivotFields(sSlicer).AllItemsVisible Then
                target.PivotFields(sSlicer).ClearAllFilters
                bRecordLayout = True
            End If
        End If
    Next slr
End If
