I've been trying to add an ImageButton object to a Calendar table cell, but
so far I am unable to handle the Command event from that button in my form's
code behind. Below is an example of what I am trying to do. The ImageButton
that is on the form handles its Command event just fine, but the ImageButton
that is added to the cell does not handle the event. Am I doing something
wrong, or is not possible to add server controls to a calendar cell? Thanks.
