I have two columns in a datadrid, startTime (e.g. 04:30 PM) and endTime (e.g. 06:00 PM). Both are strings and varchar in the database.
I want to add a column to the datagrid that displays the difference between these two times expressed in hours (e.g. 1.5 Hours). I'm trying to use an itemrenderer to do this calculation, but I've yet to be successful. Having trouble converting the strings to date, then calculate the hours. Can anyone help? Thanks, Don
