Hi, I'm trying to integrate Biometric Device with my Web Application, but the issue is code works for Sdk, and a test project in WinForms but not working for my WebApplication, the debugger doesn't goes inside while loop.
  1. try  
  2.             {  
  3.                 //ShowStatusBar(string.Empty, true);  
  4.   
  5.                 lblMessage.Text = "";  
  6.   
  7.                 objZkeeper = new ZkemClient(RaiseDeviceEvent);  
  8.                 ICollection<UserInfo> lstFingerPrintTemplates = manipulator.GetAllUserInfo(objZkeeper, int.Parse("4370"));  
  9.   
  10.                   
  11.   
  12.                 //DataTable dt = manipulator.GetAllUserInfo(objZkeeper, int.Parse(hdID.Value));  
  13.                 if (lstFingerPrintTemplates != null && lstFingerPrintTemplates.Count > 0)  
  14.                 {  
  15.                     //BindToGridView(lstFingerPrintTemplates);  
  16.                     GV_Attendance.DataSource = lstFingerPrintTemplates;  
  17.                     GV_Attendance.DataBind();  
  18.                     ShowStatusBar(lstFingerPrintTemplates.Count + " records found !!", true);  
  19.   
  20.                 }  
  21.                 else  
  22.                 {  
  23.                     //DisplayListOutput("No records found");  
  24.                     lblMessage.Text = "Caution! No Record Found!";
