I have used DateTimePicker with selectable date start and end, when binding the selected date with two way mode and entering the earlier date manually I am getting below error. Any idea?
<telerik:RadDateTimePicker x:Name="cmbDatePicker"
InputMode="DatePicker"
VerticalAlignment="Center"
HorizontalAlignment="Center"
Width="250"
Height="30"
IsInputRestrictedToSelectableDates="True"
SelectableDateStart="{Binding SelectableDateStart}"
SelectableDateEnd="{Binding SelectableDateEnd}"
SelectedDate="{Binding ScheduledDate, Mode=TwoWay}"
/>
I've tested the code snippet on my side, but I couldn't recreate any issues. The error in your screenshot appears because when you enter empty text this cannot be converted to a valid DateTime object. Also, I am not sure what do you mean by "entering the earlier date". Can you explain this?
I also attached my test project so you can take a look and tell me if I am missing anything.
