ASP.NET AutoPostBack is clearing form data

I have a radio button list and I want to perform some action when a user makes a selection.

<asp:RadioButtonList id="docList" runat="server" AutoPostBack="true" OnSelectedIndexChanged="loginUser" />

However, I get an empty value for docList.SelectedValue. I am guessing this is due to form data getting cleared upon Autopostback. Is there a way I can have AutoPostBack and not lose form data?

Yes you can by implementing it like this:

<asp:RadioButtonList id="docList" runat="server" AutoPostBack="true" OnSelectedIndexChanged="loginUser" />


public string SelectedDoc {get;set;}
protected void Page_Load(object sender, EventArgs e)
{
   if(!Page.IsPostBack){
   }
   else
   {
      SelectedDoc = docList.SelectedValue; //this will be set on postback and will contain the selected value.
   }
}
