You have two methods:
ScrollPosition = xx smoth scrolling
ScrollToNow(xx) fast scrolling
I haven't tested it when scrolling is disabled.
But you can enable scrolling just before the code scroll and disable scrolling just after the scroll.

I have to store the top position of each panel...

Click to expand...

It depends on the height of the panels.
If all panels have the the same height you can mutiliply the panel index by the panel height.
Otherwise yes, you need to memorize the top values of the panels.

What are you going to achieve with it? I recreate the scrollview with the views I want the user to see (= limit)

this is the requirement in my project because instead of creating four to five activities for this work I want to cover in one. Because my internal panels are of different height. to show the information I need to catch this event.

Hi!

Its a information getting activity in which depending upon different selection I want to show different information in the panels and on selection I finally asked user to enter some information. This can be done in four to five activities but to avoid this I am using scrollview to achieve it. As you suggested every thing is working fine only now I want to catch the following
how can I limit the scroll between two positions.
and enable/disable the scroll between these position and deactivate/activate the touch event of the scrollview

scrolled change position need to be controlled.

Handle the ScrollChanged position and call ScrollView.ScrollToNow if the position is outside of the allowed range.
