task pane vsto

[Lina]

Hi
I would like to create a guide in word and wants to create it with
taskpanes. Like the built in mailmerge guide.
I have created a taskpane with a usercontrol on which is filled with
textboxes that the user are supposed to fill. Then I want the user to click
on my "Next" button and then I would like to show a new taskpane with a new
usercontrol.
Since I'm new to vsto Im not sure if I should do this by hide my old
taskpane and create a new one or by trying to change which customcontrol that
is set to the taskpane?
Does anyone have a tip or sample code on how to do this?

Thanks
