将DatePicker绑定到日期列表

Question

Probably irrelevant, but I have an Infragistics XamDataChart that has a CategoryXAxis of Dates. I have managed to bind a date picker to the range of dates available in the chart, but I really need to bind to the specific list of dates plotted on the chart.

<DatePicker x:Name="statsDatePicker" DisplayDateStart="{Binding Path=ActualMinimumValue.Date, ElementName=xAxisPath, Mode=OneWay, StringFormat=\{0:d\}}" DisplayDateEnd="{Binding ElementName=xAxisPath, Path=ActualMaximumValue.Date, Mode=OneWay, StringFormat=\{0:d\}}" SelectedDateChanged="DatePicker_SelectedDateChanged" />

I have found that you can provide a list of blackout dates, but how does one take a range of dates I have and turn it into a range of dates I don't? Or, is there a way to provide the date picker the dates I have instead of the dates I don't?

Answer 1

Maybe something like this?

DateTime end = DateTime.MaxValue;
DateTime start = DateTime.MinValue;
List<DateTime> datesIHave= new List<DateTime>();
datesIHave.Add(DateTime.Now);
List<DateTime> allDates = Enumerable.Range(0, 1 + end.Subtract(start).Days).Select(offset => start.AddDays(offset)).ToList();
List<DateTime> blackoutDates = (from a in allDates 
                                where !datesIHave.Contains(a)
                                select a).ToList();
