I am in the process of upgrading the radcontrols to asp .net ajax. 
The raddatetimepicker is causing problems with this.
the error i get is 
Value of '1/1/0001 12:00:00 AM' is not valid for 'SelectedDate'. 'SelectedDate' should be between 'MinDate' and 'MaxDate'.
Parameter name: SelectedDate

i have three options to show a document
1) show document
2) hide document
3) show for date range (this one take a show start and show end date)

for the first two options we are saving null in the database and when this value is returned it throws the error mentioned above. it works fine for the third option. 

any ideas as to how to return a null value for a raddatetimepicker when the value in the database is null??

Thanks!

Hi Bandana,

Consider passing the selected date from your database to the date picker using its DbSelectedDate property (which accepts null values). See this online demo for details.

Hello Bandana,

If using DbSelectedDate the application should not throw an exception if the new value is null or DBNull. Setting a null value should internally revert the SelectedDate to the null value, i.e. the input value will be empty.
As the provided information is not enough to isolate the root cause of the issue you are facing, please prepare a simple, fully runnable reproduction demo, open a new support ticket and send it to us along with very detailed reproduction steps and explanations and we will debug it locally and we will do our best to help.


All the best,
