RadioButtonList lost state

[Lubomir]

Hi,

I have a radio-button list with 2 buttons. The property for this control are
set up as follow:
AutoPostBack=true
EnableViewState=true

When I clik on 1st button, it get selected, will process the url and show
some data.
When I click the 2nd button, it get selected and data from DB will be shown.

So far, so good.

But, when I select previous URL from the Address bar in Explorer (it means I
don't hit radio-button) , than no radio button is selected - the previous
selected index is lost and not remembered in a view state.

Why is this happening?

Thanks,
Lubomir

Viewstate only remembers the state of a control when you do a postback. If
you go to another page using some other method (such as selecting it from
the address bar), the state is lost because you are leaving the page.
