I am using the DateElement in MVVMCross that was forked from Monotouch Dialog.
I can get the DatePicker to appear when I touch the DateElement, the problem is I cannot see how to dismiss the PickerView once I have selected the Date.
It was completely to do with the way we use MT D, moving the DialogViewController's View into a View one level higher than expected. See my answer to this question, Back Button missing from nested Monotouch Dialog RootElement Views
