WP7 silverlight user control via popup

Question

I create a custom datepicker, I have a text box, after clicking it, the calendar opens in a popup window. What I want to do is resize the popup to show my entire calendar, but I can’t resize it ... I tried using Height, Width, MinHeight, MinWidth ... but it is not. It doesn’t work, the popup is displayed with a fixed size.

The fact is that my parent property popup is not evaluated, since it has problems with expression (according to the debugger), so I am sure that my pop-up parent is not the main screen (for example, the layout grid).

How can I, for example, open a popup in a specific context? This part of my code is not XAML, it is only C # code and looks like this:

using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using System.Windows.Controls.Primitives;

namespace CalendarBranch.components
{
    public class wpDatePicker:TextBox
    {
        private CalendarPopup calendar;
        private Popup popup;

        public wpDatePicker()
        {
            this.calendar = new CalendarPopup();
            this.popup = new Popup();

            this.popup.Child = this.calendar;
            this.popup.Margin = new Thickness(0);

            this.MouseLeftButtonUp += new MouseButtonEventHandler(wpDatePicker_MouseLeftButtonUp);

            this.calendar.onDateSelect += new EventHandler(onDateSelected);

            this.IsReadOnly = true;

        }

        protected void wpDatePicker_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
        {
            this.popup.Height = this.calendar.Height;
            this.popup.Width = this.calendar.Width;
            this.popup.HorizontalAlignment = HorizontalAlignment.Center;
            this.popup.VerticalAlignment = VerticalAlignment.Center;
            this.popup.HorizontalOffset = 0;
            this.popup.VerticalOffset = 0;
            this.popup.MinHeight = this.calendar.Height;
            this.popup.MinWidth = this.calendar.Width;

            this.popup.IsOpen = true;
        }

        private void onDateSelected(Object sender, EventArgs ea) {
            this.Text = this.calendar.SelectedValue.ToShortDateString();
            this.popup.IsOpen = false;
        }

    }
}

PS: the Calendar class is just a UserControl that contains a grid with multiple columns, HyperLinkButtons and TextBlocks, so nothing special.

Thanks in advance guys;)

The pop-up control resizes to fit the contents within it. For example, if you set a Popup child in a StackPanel with a width / height set to 100, the popup will be 100x100.
