MS web UI controls: unable to build

[NightRaVeR]

Hi guys


I am using the Microsoft.Web.UI.Webcontrols DLL in my project for a
treeview.
This all worked fine, until a fex days ago. Suddenly my project does
not build anymore.

It says that I should add a reference to the DLL with
publickeytoken=null

I find this strange, but hey, I just gave it a try, but it didn't work.

So uninstalled the controls, and tried referencing the DLL without the
controls being installed on the pc, but did not work either. So I
reinstalled, but still no succes, although the sampleapp that came with
the controls does seem to work.

I do not know what I can do to solve this anymore, and it is getting
urgent.

Can anyone assist???

Kind regards
