As we all know, the Calendar control causes postbacks that we often do not
want. This will obviously cause the Page's Load event to be triggered. I
have code in my Load event that I want executed under all the other
scenarios that might cause postbacks, but now when the user is simply
changing the date of a Calendar control. Is there any way to determine what
control caused the current postback so that I can determine whether my
Calendar control caused it or whether another control did? Thanks.
