Dynamically adding Textbox w/MaskedEditExtender into a calendar cell. How? Ill pay you for answer.

Question

I have included the source code.  This fails everytime.  This problem shouldn't be as hard as it is, but if someone could give me a good solution I would be greatly happy.

PS The code needs to be ran in a project because simply looking at the code doesnt describe the problem.  The error that I get says that the "Page cannot be null".  I need a pros help!  And yes! If someone gets me an answer that works ill send you a check for 50 American Dollars. Scouts honor.
