How do I load a user control in a web form first, so that the web form's
page_load acts according to events on the user control?
In my code below, I have a user control at the top of every web form, in a
panel. I have 2 other panels on the web forms, to be shown individually
depending on what the user clicks on the user control. However, when the
button on the user control is clicked, the web form page_load fires first,
then the control's page_load, then the event of the button click in the user
control fires last, so there is no response from the web form because it
has already been loaded. What do I do about this, I've seen similar
dilemmas in this newsgroup and find hundreds of articles in ms, but none
that solve this one, unless I'm just not putting the pieces together.
Thanks for any help, advice!
