I have implemented the KenoUI javascript Grid within an application. I have the filtering all working correctly, except it seems the KendoUI Grid doesn't support the ability to filter blank/emtpy field values.
Basically, in the filter dropdowns, I need there to be a "Blank" option that allows for only items where that field is either null or an empty string. How do you add this option to the dropdown?
