Hi Frinavale,

Thanks for your reply.
Yes I have set the ValidationGroup property on the summary and the validators.

But the .NET validators and validationgroup properties aren't designed
to be used like this. But I was wondering how to extend the
validators to support something like this.

...

Anyone suggestions how to cleanly realize a page with multiple validationsumma ries that display only the messages of controls that belong to the same validationgroup ?

So for example three validators that belong to validationgroup 'test1' only display in validationsumma ry with validationgroup 'test1', and three other validators (vg = 'test2') at the same time display only in another validationsumma ry (vg = 'test2')

Thanks...
