I am using a callback panel which optionally contains a calendar control. The default for the calendar control is no date selected and a hint string. As part of the call back, if the calendar control exists I want to reset it to no date selected with the hint string; however, now matter what I do, any selected value is retained across the callback rather than being cleared.

I am clearing the controls, creating a new datepicker control and have each tried the following

ctlDatePicker1.SelectedDate = Date.MinValue
ctlDatePicker1.SelectedDate = Nothing
ctlDatePicker1.VisibleDate = Date.MinValue
ctlDatePicker1.VisibleDate = Nothing

as well as not setting any value before adding it to the panel.

What should I do to create any empty value

Thanks

Thanks for that.

The problem is that the first time I display it it is fine (shows the 'null' value). However, after a call back to recreate the calendar, although I set the new instance to null, the calandar on return shows the date it was before the call back.

Hope that makes sense.

Thanks
