Hi, I use the "general discussions" section, as there's no FilterMenu section, and I think that this component is only used inside the grid. But, because we need to filter our datasource for the grid, and others containers, we decided to use the kendoFilterMenu directly outside of the grid.
I see that there's an operator named "isnullorempty".
I think it's a new one, because I don't see in the dataSource doc.
Nothing in the and in the grid doc too.
The only place I read about it is in the filterMenu doc
We'll certainly use it to filter text, to manage these cases: empty string, null, or undefined.
But, undefined are not returned.
When I filter the field "text", with "Has no value", I get 1001 and 1002 in return, not 1003.
I don't think any combination of filters can return "undefined" value?
Can we edit the original filter method to make it apply the filter to undefined also?
Or should we absolutely need to create a custom filter function?
