Basically editing of TimeSpan object using TimePickers is not directly related to KendoUI (the TimeSpan object represents period using ticks but the TimePickers are expecting Date object as value), but is a general programming task. There are several ways to do that and which one you would choose depends entirely on you and on the exact setup that you have – more information on this matter is available in various resources on the Internet. For example if the TimeSpan is expected to be set to maximum 24h you can create ViewModel which to contain DateTime field. Then you can convert the TimeSpan to DateTime on the server - for example the period can be calculated based on given date with time information 00h:00m:00s to the one selected currently in this field.
