[OPEN] [#163] Gridpanel Remote Filter on Date column not working
Hi,
I am trying to do a remote filter on a date field but it does not work.. the filter string for the date column is not passed to the server. See my sample from the online examples below.
Please provide a fix that does not require a SVN update.
