I integrating the Bio-Metric Device with my web application, the issue is its not returning any data but the same code works for WinForms, I'm unable to get where i'm making the mistake...

any good idea/guide will be thanked with appreciation.
Thanks :)

Here is the code behind Get User Data Button.

try{
lblMessage.Text = "";

            objZkeeper = new ZkemClient(RaiseDeviceEvent);

            ICollection<UserInfo> lstFingerPrintTemplates = manipulator.GetAllUserInfo(objZkeeper, int.Parse("4370"));





            if (lstFingerPrintTemplates != null && lstFingerPrintTemplates.Count > 0)

            {



                GV_Attendance.DataSource = lstFingerPrintTemplates;

                GV_Attendance.DataBind();

                ShowStatusBar(lstFingerPrintTemplates.Count + " records found !!", true);



            }

            else

            {

                //DisplayListOutput("No records found");

                lblMessage.Text = "Caution! No Record Found!";

                pnlAlert.CssClass = "alert alert-warning";

                pnlAlert.Visible = true;

            }



        }

        catch (Exception ex)

        {

            lblMessage.Text = "Can't Fetch the User Data!";

            pnlAlert.CssClass = "alert alert-warning";

            pnlAlert.Visible = true;

        }

and Here is the Method from which its going to get the data.
In this chunk of code my Debugger is not entering the While Loop.

public ICollection GetAllUserInfo(ZkemClient objZkeeper, int machineNumber)
{
string sdwEnrollNumber = string.Empty, sName = string.Empty, sPassword = string.Empty, sTmpData = string.Empty;
int iPrivilege = 0, iTmpLength = 0, iFlag = 0, idwFingerIndex;
bool bEnabled = false;

        ICollection<UserInfo> lstFPTemplates = new List<UserInfo>();



        objZkeeper.ReadAllUserID(machineNumber);

        objZkeeper.ReadAllTemplate(machineNumber);





            while (objZkeeper.SSR_GetAllUserInfo(machineNumber, out sdwEnrollNumber, out sName, out sPassword, out iPrivilege, out bEnabled))

            try

            {

                for (idwFingerIndex = 0; idwFingerIndex < 10; idwFingerIndex++)

                {

                    if (objZkeeper.GetUserTmpExStr(machineNumber, sdwEnrollNumber, idwFingerIndex, out iFlag, out sTmpData, out iTmpLength))

                    {

                        UserInfo fpInfo = new UserInfo();

                        fpInfo.MachineNumber = machineNumber;

                        fpInfo.EnrollNumber = sdwEnrollNumber;

                        fpInfo.Name = sName;

                        fpInfo.FingerIndex = idwFingerIndex;

                        fpInfo.TmpData = sTmpData;

                        fpInfo.Privelage = iPrivilege;

                        fpInfo.Password = sPassword;

                        fpInfo.Enabled = bEnabled;

                        fpInfo.iFlag = iFlag.ToString();



                        lstFPTemplates.Add(fpInfo);

                    }

                }



            }

            catch (Exception ex)

            {



            }

        return lstFPTemplates;

    }
