How to set the background color dynamic

Hi,

I've the problem that the background color is set in the codebehinnd, but isn't changed in the view.
What's wrong with my implementation?

The backgroundcolor is "#FFB612" and it will be changed to "#CCDC00". But I still see the "#FFB612" color in my browser.

See code:

public void _dayPilotScheduler_BeforeEventRender(object sender, BeforeEventRenderEventArgs e)
{
e.ToolTip = "Move over for more information";
e.EventClickEnabled = true;
// get column
var foundSchedule =
Schedules.Find(
schedule => (schedule.UniqueID.ToString() == e.Value));

if (foundSchedule != null)
{
switch (foundSchedule.ScheduleApplicationStatus)
{
case eScheduleApplicationStatus.BroadcastInFuture:
e.BackgroundColor = "#FFB612";
break;
case eScheduleApplicationStatus.Inactive:
e.BackgroundColor = "#FFB612";
break;
case eScheduleApplicationStatus.Error:
e.BackgroundColor = "#D0103A";
break;
case eScheduleApplicationStatus.BroadcastingNow:
e.BackgroundColor = "#CCDC00";
e.DurationBarColor = "#CCDC00";
break;
}

e.DurationBarColor = "#FFFFFF";

e.InnerHTML = string.Format("{0} - {1} - {2}", foundSchedule.ApplicationID,
foundSchedule.ApplicationTitle, foundSchedule.TargetName);

}

e.EventRightClickEnabled = false;
}

Kind regards,

Rob
