	Hello, Using Winforms > Scheduler > Timetable display, is there an easy way to change opacity or enlight/darken past events to increase the visilibity of futures appointments? Kind regards

	Hi, You can set collect the past items and manually set their background brush to a brighter, darker or a semi-transparent version of the default brush. For example, to change the background of an item to a more transparent one, use the following code: Code var defaultBrush = calendar.ItemSettings.Style.Brush as MindFusion.Drawing.SolidBrush; item.Style.Brush = new MindFusion.Drawing.SolidBrush(Color.FromArgb(100, defaultBrush.Color)); To collect the past items, you can use one of the Schedule.GetAllItems overload, or you can do it manually, like this: Code foreach (var item in calendar.Schedule.Items.Where(i => i.EndTime < DateTime.Now)) { // Set the item's background } Regards, Meppy

	Thank you for your quick reply! If I do this in the Draw event, it will not overload the method?

	Hi, The Draw method is not the best place for this because it is invoked very often whereas you need to set the item backgrounds rarely, possibly even once when the items are created. Move this code to an ItemCreated or ItemModified event handler. Regards, Meppy

	Sorry for the delay... Thank you for your answer, job's done! Except one tiny thing: surprisingly, the _ItemCreated event is never raised (yes, obviously the event handler is correctly set ) ?! However the _ItemModified is perfectly raised...

	Hi, ItemCreated should be raised for appointments created interactively the built-in way, by selecting a time range and typing. It's probably not raised if you add items from code, e.g. in response to click or drag/drop events. Regards, Slavcho Mindfusion
