As advised here [ASP.NET Response.Redirect(Request.RawUrl) doesn't work](https://stackoverflow.com/questions/12737240/asp-net-response-redirectrequest-rawurl-doesnt-work/12737254#12737254) I did put autopostback = true on a dropdown list to reload my page.

But after reloading it resets also the selected item to first one.

How to keep my previous value before reloading the page then ? I thought autopostback would do that job ?
