We have a RadDatePicker that is used to gather a required field from the user. We have also activated the field level notification to provide immediate feedback to the user as they are typing in the date. We have tied into the ParseDateTimeValue event so we can set a flag indicating whether the TextToParse contains a valid or not, and this works almost flawlessly. The one issue we have occurs when the user highlights the entire date in the text field and hits the DEL or Backspace key to delete the entire date. In this particular instance no ParseDateTimeValue event is not triggered, even though it is triggered for both DEL and Backspace when only part or none of the date text is selected.
As a workaround we attached a KeyDown event handler, but it is exhibiting the same behavior, it is properly triggered for all KeyDown events except when the entire date text is selected and the DEL or Backspace key is pressed.
Has anyone else encountered this behavior and/or have a way to correct or bypass it?
This was observed under Windows 7, IE 8.0.7601.17514 using C#.
