If the drop down list is asp control then on selected change put the selected value to viewstate
else if it is html controller pass the data to controller via jquery and save it in viewstate.
or you can get the value of a html drop down list value in code behind by
string value= Request.Form["Drop"];
where name of the DropDown is "Drop"

Solution 1

U can follow the solution given by Arkadeep.

Viewstate is for a page. If at all your going to navigate to other screen then you can use query string or Session.
