devexpress - How can the enduser clear a DevExpress StringEdit editor?

Question

In the UI we have a textbox which is a DevExpress.ExpressApp.Win.Editors.StringEdit.

We set its properties as follows:

control.Properties.Mask.MaskType = MaskType.DateTimeAdvancingCaret;
control.Properties.DisplayFormat.FormatString = "yyyy.MM.dd";
control.Properties.DisplayFormat.FormatType = FormatType.DateTime;

When the textbox gets the focus it is empty. When the end user presses any key the control displays a valid date. The user modifies the date. Now how can the user empty / clear this textbox (using the keyboard)?

(Del, BackSpace does not work)

Thx

All common text editing features are available in text editors. This includes typing characters, deleting them using the BACKSPACE or DEL keys, etc. Note that end-users can press the CTRL+DEL combination to remove the editor's entire content.
