System.OutOfMemoryException problem

Hi Guys,

I have an aspx page that include some Ajax components (UpdatePanel,
ProgressBar, Extenders) and a wizard for about 15 pages and in every page I
am adding some labels, textboxes, dropdownlists, checkboxes.
and now I'm up to page 8 in my wizard and if I add some more controls in my
wizard page or even moving backward or forward to another wizard page some of
the controls will change to gray box with an error like this eg. -(Error
Creating Control -Label65 Exception of type 'System.OutOfMemoryException'
Was Thrown).
I tried close and reopen the application or to restart the computer but
still getting the same error!!!?


Thanks
