asked on
Page_Load event executing twice, after Login
Greetings all
I have a somewhat strange scenario. I have a page with a login control on it. in my Page_Load event I am calling a small routine tahts ets various button states. I placed a breakpoint within that routine, in order to do some checking. What I noticed was that after entering user name and password and clicking the LogIn button, my breakpoint was reached twice!
Any explanations?

It could be that the page load event handler got registered twice. Set autoeventwireup=false in your Page directive. Then rerun the program again. If it hits your breakpoint only once, that was the problem. Somewhere it got registered explicity, then autoeventwireup registered it again.
ASKER
Thanks 4 the feedback.
The code is not under any "if (!Page ....) - some of the struff is needed regardless of the which.
I tried the auoeventwireup -set it to false -- 2 things happened -- (1) Page layout is screwed up (appears that the csss isn't loaded) and (2) the breakpoint (previosuly reached twice) is never reached.
In breaking where I did (see snippet), after setting autoeventwireup back to true, I noticed that on the first "pass", the user is not authenticated (btnSubmitChangesX is null) but on the 2nd "pass" the user is (btnSubmitChangesX = ....)

Just did a check on the Postback (set breakpoints). When I click the "Login" button, the first load is a PostBack, but the second load is not.

OK.
So, bottom line = everything is as it should be, and all I need to do is keep that in mind when I code.
So, bottom line = everything is as it should be, and all I need to do is keep that in mind when I code.
Like I said in my last post, you need to put your routine in the "If not postback " block if you don't want it to be executed more than once, otherwise, any posttack will cause the execution of the routine.
The reason the Page_Load was hit twice is that the first hit is caused by the button click's postback, and the second one is caused by the return of the authenticated request.

If everything is fine, please close the question.
