How to Set the range of the dates

[balv]

Hi All
I want to Set the range of the dates the user will be able to navigate to, and a constraint on the dates that can be selected similar to RadCalendar.
For example is 01/01/1900 to 12/12/9999

Hello,

You need to set SelectableDateEnd and SelectableDateStart to the desired start and end dates. You can set them either in XAML or Code.

Let me know if you have further questions.

Best wishes,

I use version Q2 2010 SP1 but I can not see these properties in RadDatePicker

I am sorry for error of omission. I found these properties and use it but  when I type 01/01/1000 and Click button to show selectedDate then has any error.
How to I prevent user choose or type invalid date(not between a range date)
thanks.

Hello,

This is the way RadDateTimePicker work at the moment, the properties you have used restrict just the dates selected from the calendar. We decided to leave more space for customization and that is why we have not restricted the date parsing in such specific scenarios. However you can easily manipulate it with some code using the ParseDateTimeValue event. With it you can set the range for the parsing. You can take a look at this help article for more info. You can also create a custom message, for example "Date not in allowed range".

 Let me know if you have further questions.

All the best,
