In my page I have a DropDownList, whose selected value(posted to the external site) determines the page to be opened on the external website. When I select a value in the DropDownList and click on the LinkButton it works fine, opening the
external page on another window but when I come back to my page and change the selection in the DropDownList, even without clicking the LinkButton another window is popped up with the previous results and not for the changed value of the DropDownList.
Why does this happen? Could anybody suggest a good way to solve the issue?
