Thanks Jorge,
I created a new web control library project to test this. I had one
property that did not specify the defaultvalue attribute, but gave the
property a default value by assigning a value to the private variable. That
value correctly displayed in the IDE. I then added the defaultvalue
attribute and assigned it a different value. There was no change in the
IDE. Am I missing something?
