Datepicker calendar does not stay open

Question

See more:

We have a datepicker control in our application which is actually drawn using a visual brush. Only when we click on the datepicker, a datepicker object is created. This datepicker class is inherited from the System::Windows::Controls::DatePicker and we have overridden the required functions.

The issue is when we click on the datepicker for the first time, the calendar does not stay open. It appears and suddenly disappears. Only on the second click it stays open. I tried setting the IsDropDownOpen property and also getting the PART_Popup to set the StaysOpen property, but both failed. Any help on this is welcome.

All right, there can be too many ways to screw up things. How can we know which way have you chosen? :-)

umm..Should I explain more? I really can't find a workaround for this.

When a particular window is loaded, we draw a datepicker using a visual brush at a calculated position. As per requirement, the actual control should be created only when the datepicker is clicked. And so on the click, we have created the real datepicker object and have set the IsDropDownProperty to true. But this does not work as expected. The control is created alright, but the drop down does not stay open until the next click. This does not happen every time though. The control is drawn to a canvas(in the code behind of a WPF window).
