I have a pqGrid whose first column which is hidden has numbers in increasing order(0,1800,3600), i have a second column which is not hidden, I want to sort my grid when i click my second column but it should be based on the values of first hidden column.
If you wanna know::
My second column contain time of every half hour from 6 am to 6 am(6:00 AM, 6:30 AM.....12:30 PM......5:30 AM), and the fist hidden column contain the time in seconds passed from 6:00 AM.
