DateTimePicker stays on top when mdichild closes

[Peter]

Hi,

I've got an MDI Application in which there are MDIChildforms whom contain RadDateTimePickers. when the Windowstate of the mdichilform is normal, the datetimepicker is selected (showing the calendar) and i then close the childform, the calendar still stays on top. If you click inside the calendar, the application will crash because the control doesnt exist anymore...

Any help?

Peter

Hello Peter,

This is one very strange issue. Have you tried to hide the dropDown when changing the state of the form?
For example to hide the popup you can use the following:

(datepicker.DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar).PopupControl.Hide();

I hope this helps.

Please, write me back if you need more assistance.

Kind regards,

We've experienced the same strange behavior.  Honestly, it shouldn't be the developer's responsibility to clean up the rad controls when a form is closed.

Hi Kevin Meyer,

We are still investigating the issue. I believe we will address it in time for the next major release.
