Answer 1

Thanks @GauravKP for your help. I used xmlns:sys="clr-namespace:System;assembly=mscorlib" for getting Current date as

 SelectedDate="{x:Static sys:DateTime.Now}"

and using DisplayDateStart="{x:Static sys:DateTime.Now}" to hide previous date.

<DatePicker Grid.Column="0" Name="datepicker" DisplayDateStart="{x:Static sys:DateTime.Now}" SelectedDate="{x:Static sys:DateTime.Now}" ></DatePicker>

at codebehind you can define display date like this

datepicker.DisplayDateStart = DateTime.Now;
