Question

I have a code block that does not return the expected data values.

protected void Page_Load(object sender, EventArgs e)
{
corpEmployee.Employee editEmp = new corpEmployee.Employee();

editEmp.EmployeeID = PatientCustomerID.Value;
corpCustomerMgr.GetEmployeeRecord(editEmp);

tboxFirstName.Text = editEmp.EmpFirstName.ToString();
tboxLastName.Text = editEmp.EmpLastName.ToString();
tboxCity.Text = editEmp.EmpCity.ToString();
tboxAddress.Text = editEmp.EmpAddrLine1.ToString();
}  


public static void GetEmployeeRecord(corpEmployee.Employee QueryData)
{
    try
    {
        List<corpEmployee.Employee> empRecord = new List<corpEmployee.Employee>();
        corpCustomerDAL.GetEmployeeData(empRecord, QueryData);
    }
    catch (Exception ex)
    {
    LogAppError(ex.ToString());
    }
}  

When corpCustomerDAL.GetEmployeeData(empRecord, QueryData); is executed, empRecord is returned with the Employee object with correct property values. However, when the code comes back to corpCustomerMgr.GetEmployeeRecord(editEmp); the employee object has null values.

How can I get the Employee object values back to the Page_Load routine?

Answer 1

Based on your comments, it looks like you are populating empRecord with the employee data you require. The simplest option is to return the populated record from GetEmployeeRecord:

public static corpEmployee.Employee GetEmployeeRecord(corpEmployee queryData)
{
    List<corpEmployee.Employee> empRecord = new List<corpEmployee.Employee>();
    corpCustomerDAL.GetEmployeeData(empRecord, QueryData);
    return empRecord.Count == 0 ? null : empRecord[0];  //or empRecord.FirstOrDefault()
}

You should then change the start of your Page_Load handler to:

corpEmployee.Employee queryEmp = new corpEmployee.Employee();
queryEmp.EmployeeID = PatientCustomerID.Value;

corpeEmployee.Employee editEmp = corpCustomerMgr.GetEmployeeRecord(queryEmp);
