PostBack Event Firing Sequence

[Guadala Harry]

Just wondering if I can count on Page_Load *always* firing before event
procedures of other controls on the form.

E.G., suppose I have a DropDownList server control and it is
"autopostbacking". Will Page_Load always fire before the
SelectedIndexChanged event of the DDL?

Thanks.

Hi Guadala,

The Load event will *always* fire *before* the change events, I promess

Yes they will always be called after page_load, the order goes like this

Page_Init
Page_Load
Validation
Event Handling (your control events get fired here)
Page_Unload

You can place a breakpoint in your "page_load" and see what happens.
Remember to
configure your project to use "debug".

Alternatively, you can "cause" an exception in you code and observe the
order on the call stack.
