The grid search widget might be of help here. From the documentation "Any search criteria that can be written in XPath is supported". The xpath constraints you want are
[attributeName = empty]
attribute not empty
[attributeName != empty]
Association not empty
Here is the link to the widget
Hope this helps!
Edit: The github has a nice example project that show show to configure the AnySearch functionality.
The test folder has the example project. In the project search for the page called "Filters". The Any Search tab has the example.
Filtering data is standard functionality on datagrids by adding search fields to the designated area:
But Im guessing your need goes beyond this functionality: what is it you want to do that is not possible using standard search functionality?
Yes this is standard search functionality. But i like add search (Empty or not datavalue), this is classical in excel.
