Question

First, I have an TextField. When user click on it, DatePicker will appear (in the same textfield’s view). After user choose date, DatePicker should be disappear, and textfield should show selected date.

I have tried this code in ViewDidLoad:

    txtTime.TouchDown += (sender, e) => {
    UIDatePicker picker = new UIDatePicker (new RectangleF (0, 20, this.View.Bounds.Width, 10));  
    picker.Date = DateTime.Now;
    picker.Mode = UIDatePickerMode.Time;
    this.Add(picker);
    txtTime.ResignFirstResponder();             
};

But I have some problem:

1. Can’t disable keyboard (ResignFirstResponder() doesn’t work)
2. I don’t know how to handle select date even of DatePicker to set for Textbox
3. The DatePicker appear without ‘close’ or ‘done’ button, so can’t return to textfield view (could I use Datepicker without actionsheet?).

How can I solve that?

In the book “Developing CSharp Apps for iPhone and iPad using MonoTouch – 2011”, chapter 7 “Standard Controls” you could see example of how to implement picking date.

Basic idea is to:

• Put DatePicker on a UIActionSheet (create custom class, which controls DatePicker and UIActionSheet actually);
• Add label “Choose date, then press OK” and buttons “OK”/”Cancel” to the top side of UIActionSheet’s View;
• Show UIActionSheet on textField.EditingDidBegin event.
