I am rebuilding an app that I made using 3.3.1 and the GridSummary plugin. I would like to create a couple of custom summaryType fucntions and so far I am unable to find a way. The only options I have are the Sum, Count, etc, but the docs mention that the summaryType can be a function. Is that not possible in the designer? If not, is it coming?
Is this still an outstanding bug? Looks like it has been around for some time.
The only workaround I could find was to create an override then specify summaryType: function(records) in the override. The problem with this solution is that you loose the ability to edit your grid using designer.
