Otis,
My vs.net version is 2008 and yes, the webform was in design view. I've tried to drag it to the source view, but then I get the message:
The operation could not be completed. Ongeldige FORMATETC-structuur
(Nice touch of dutch there btw
)
Weird thing is that is did work after I first installed it into the toolbox (I just dragged it to the design view and the component appeared including the 'register' tag in the aspx source).
Vs.net however didn't persist the toolbox then and I had to install it again and again. At this moment the datasource2 is present at vs.net startup (somehow vs.net has remembered) but now I just won't work.
Personally I think vs.net is to blame because the datasource2 does behave normally on other computers at my department. Still, any pointers to get the component working again would be appreciated.
