I need some pointers to start on this.We are building a time off application where three instances of a calendar control will be displayed ( prev - current and next month) now users can click on various dates accross all three instances and then a count of number of days should be diaplyed in the parent textbox.
To begin with this, i started with adding the dates clicked by the user in Calendar2_SelectionChanged method into a list<> so that i can get the all dates user clicked and then add it to calander's selected dates collection. But this throws an e" object reference not set" error.
Is there anyother way to get all the dates that user click onthe calendar( note the dates doesn't get highlighed so seleteddates doesnt work)does anyone has a good example for this.
once a user select an item from dropdownlist > Dates from DB are shown on calendar in pink color.
The problem now is when i want to select new dates the selected dates(in pink) become deselected .. I want them to stay selected so i can know which dates are already used .

I am generating multi-series graphs with the date along the X-Axis. The problem is that not all of the series in the graph have the same dates in the date range. Meaning that if I choose 1 Feb through 30 Apr that one series may have data that starts at 1 Feb but only goes through the end of March but another series may have data for the entire date range. This skews the charts I need to create. Go, given the date range taken at the begining of the query I'd like to generate a list of dates and populate the data to be graphed, padding those series with 0's for those dates that have no data.
