Repeater Not Populating Items on PostBack

I'm not sure if this was answered, but I have run into this
problem in the
past.

The problem is that sometimes in a post back ot in an event
handler that
some of the controls do not seem to have their values set.
Given that you
don't know how to get all of the values without having to
get them from the
form variables directly.

There is a built in solution that fixed this problem. 

EnsureChildControls()
http://msdn2.microsoft.com/en-us/lib
rary/system.web.ui.control.ensurechildco
ntrols.aspx

You want to place that call [EnsureChildControls()] inside
your event
handlers. This will make sure that all child controls for
this page exist
and have retreived their values from the post variables
before you try to
use them.

I hope this helps everyone.

Mike

Shawn,
        That is exactly what was happening.  I needed to
handle it in an
event handler.  This was being called later by Page_Load.

Most likely you are re-populating the data bound items of
the repeater
before your events fire.  What are you doing in Page_Load? 
(Did you forget
a IsPostback() check?)

I have a Repeater control in 2.0 that is not filling it's
Items collection
on postback even though ViewState is enable for the page and
the Repeater.
Why would this be?
