If you look at the two attached screen shots. The date range picker is initialized with a start and end date. If the start date is changed, the end date is reset to 1/1/0001.
I have configured the date range picker as:
<
TelerikDateRangePicker
@
bind-StartValue
=
"@NewRecSet.StartDate"
@
bind-EndValue
=
"@NewRecSet.EndDate"
Min
=
"DateTime.Today"
/>
My expectation is that the end date should not change from what was set as the initial value.
