First of all i suggest you to the KB article: How to select rows via an unbound checkbox column. Starting with version 13.2, the GridView in the XtraGrid control provides a built-in checkbox column for multiple row selection.
Is there a minimum age to raft or upper age limit? A. 7-years-old for the Classic and 12-years-old for the Challenge. While there is no upper age-limit, we expect everyone to reasonably evaluate his or her fitness level before taking a whitewater rafting trip.
We do always reserve the right to change minimum age, fitness and weight requirements depending on water flows. Also, a section of river can be Class III when the water is low and when it is high. Sometimes high water bumps a Class III section up to Class IV, but sometimes it does not. Whitewater river rafting is not like a fully controlled Disneyworld ride.
