Hi, i have a RadDatePicker in EditForm in RadGrid.
The column in RadGrid consist of EditButtonColumn, Name, StartDate, EndDate.
when i click Edit, it shows error:
Sys.WebForms.PageRequestManagerServerErrorException: Specified cast is not valid.
I assume this is because the value StartDate and EndDate is empty/null.
my code to assign the value to RadDatePicker is like this:
How to set RadDatePicker, when there's no value, shows no error. And if there's a value, the value of StartDate and EndDate will set to TextField and SelectedDate in RadDatePicker
Thank you very much
