True if the element can be focused

Called when a key event occurs.

Close the dropdown and commit the selection if requested. Make sure to set the selection after the dropdown has closed Don't trigger any unnecessary navigation as a result of changing the selection.

If Key.Enter is pressed, DatePicker will parse the Text no matter it changed or not

If EditableTextBoxSite loses focus and Text has been changed, DatePicker will parse Text

If Text has been changed, the flag Flags.IsTextChanged will be set to true, so DatePicker can decide to parse the Text or not

If we (or one of our children) are clicked, claim the focus

Select the focusable date

Update the Text to the TextBox in editable mode
