You can use Session to store the selected value for dropdown list.
and after browser back button is clicked , check for that session is not null and get your selected value.
If you want code for it, let me know.

yes please..i think that i will need the code. i tried the session on page load but i think on the back button click of browser page is load from the cache and not from the server so page load event not called and not getting exact result, please share some code if you have.

thanks in advanced

inside DropDownSelectedIndexChanged event , put Session["SelectedIndex"] = dropdown1.SelectedIndex;

and in page_load event
{
If(!IsPostBack)
{
If(Session["SelectedValue"]!=null)
dropdown1.SelectedIndex = Convert.toInt32(Session["SelectedIndex"].toString());
}
}

Solution 3

The back button click of browser page is loaded from the cache and not from the server.
Use session to store selected item in dropdownlist, session values is available across asp.net pages.
