Hello all,

This probably applies to controls other then the listbox but it's what
I'm having my problem with now. Can anyone tell me if the databinding
event is called late in the cycle or not. I ask because when I use a
declaritive SqlDataSource control with my list box I am checking the
listbox.Items.Count in the page load event and it's always zero.

I wanted to do a foreach ListItem in listbox.Items but it's empty.

Thanks

Put the foreach loop in the PreRender event for either listbox or the page.
In PreRender event controls are already fully built.

Page_Load is one of the first events that fires. You want to get the
count during the DataBound event of the ListBox

OK, I manage to find another way to make this work. If I call the
listbox.Databind() method it binding happens earlier so I now do this
before I want to do the foreach loop.

Thanks for all your answers. Knowing that I can also do this on the
PreRender event is good also.
