Thanks to jadach for pointing out this post
Seems to do the job. However, there also seems to be a catch ... if I then sort by clicking the column header, the filter is lost. i.e. all data are returned, not just the filtered records.
Is there a way to keep the filter in place after rendering the initial data?
Thanks in advance.
PS At the risk of stretching this post too far, I would like the user to be able to set the date range, rather than making this a design time parameter selection. Should I start a new topic?
