Hi ,

I have set value in viewstate in one of my pages and tried to get in same page but i'm getting it as null. I also tried to get and set using session and hiddenfield , when i debugged it , the value is set but when that function complete the value becomes null.

Using !ispostback im using viewstate of username , and then i used jquery dialog and passed that textbox value in that dialog to perform some function in which im getting the viewstate but i am getting it as null.

Need help

Thanks


Following is the code :

protected void Page_Load(object sender, EventArgs e){

        if (!IsPostBack && Request.Form["MethodName"] == "SendReply")
        {
            var a = Request.Form["Reply"].ToString();
            SendReply(a);
        }

        if (!IsPostBack && Request.Form.Count ==0 )
        {
            if (Request.QueryString["productId"] != null)
            {
                    //other unrequired code removed for sake of easiness

                        hdn.Value = Membership.GetUser(info.Mail).UserName;
                        //Session["usr"] = Membership.GetUser(info.Mail).UserName;

                    }
            }
        }
        else if(IsPostBack)
        {

        }
    }
private void SendReply(string a)
    {
        try
        {
            string username = Membership.GetUser().ToString();
            if (username!=null)
            {
 //this condition is not running because im getting hdn.value=""
                if (hdn.Value!=null || hdn.Value!="" )                      {                                  var aa = (string)Session["ownerid"];                                  Session.Remove("ownerid");                                                 }

            }
        }
        catch (Exception)
        {

        }
    }
