Disable left Click in Day Pilot Schedule

Unfortunately, this is not supported in the ASP.NET version of the Scheduler. In the JavaScript version, it's possible to customize the behavior using onGridMouseDown:

The implementation could look like this:

dp.onGridMouseDown = function(args) {
  if (args.button === "left") {
    args.action = "None";
  }
  if (args.button === "right") {
    args.action = "TimeRangeSelect";
  }
};
