Change sidebar outlook

I have widgetlogics for the sidebar. I want some speciel info at the sidebar to show when I click for the “dante”.
How can I take away some widgets in the sidebar from a speciel page (dante)?
I would like to just have in the sidebar for the page Dante, the text “bra att veta”-text an not the “senaste nytt, kalender o blandat”.
How do I do? (If I don´t want to code the sidebar with php, since I can´t that…)

Thanx!
