can not add the SqlDataAdapter to the toolbox ???

[cmrchs]

Hi,

In a webproject, I right-click in the toolbox and select 'Choose
Items...'
I select the SqlDataAdapter control in the listbox, then OK but the
control is not added to the toolbox ???

it works with a WinForm application though.
is this a normal behavior in VS.NET 2008 'cause this used to work in
2005

So, how can i add it ?

thank you
Chris
