name first column : dateReceiving name second column : dateSending
data :
dateReceiving -------- dateSending
2001/01/01 -------- 2001/01/03 2001/03/08 -------- 2001/03/12 2001/11/19 -------- 2001/11/24 2001/11/11 -------- 2001/12/18 I want to display the time difference between sending and receiving in list box.
How do?
If you are using DateTime in your cells you can do something like that:
DateTime time1: your first column
DateTime time2 : your third column
TimeSpan diff = time2.Substract(time1);
Datetime: http://msdn.microsoft.com/en-us/library/system.datetime.aspx
TimeSpan: http://msdn.microsoft.com/en-US/library/vstudio/system.timespan.aspx
Edit: If your question was about multi binding => Bind an element to two sources
Convert each date value to DateTime object and then subtract them , this will create a timespan obejct which is suitable to your situation
DateTime receivedDate = new DateTime(year, month, day); DateTime sendDate = new DateTime(year, month, day); TimeSpan ts = receivedDate - sendDate;
