Developer Express controls are usually very flexible and judging from this support article you can achieve what you want to do with their DateEdit control.
The ease with which you can do this will depend on the dates you want to restrict. For instance, if you all you want to do is specify a range of valid dates to pick, then you can use the MinDate and MaxDate properties to set the bounds. If however, you want to cherry pick certain days within a range (for instance, no weekends), there is no built in method for doing this.
