i have noticed the following strange behavior with the vb.net ide :

sometimes i look at the html view of a web form ... and the tags for various
web controls are not listed :

for example:

<asp: textbox ... >

in fact, sometimes a very large % (~75%) of the controls on the form are
not listed in the html view.

the controls which are listed *seem to be* the controls which i have been
working on most previously.

is there any way at design time to force html view to be regenerated from
the web form view (as i assume this is what is being done behind the
scenes)
