I used this side to create my demo application
http://windowsclient.net/learn/video.aspx?v=314683
The site was very useful in getting my started and in their example, they created a file called EmployeeRepository.cs which appears to be the source for the data. In their example, the data was hard-wired in code. So I'm trying to learn how to get the data from a data source (like a DB). In my specific case, I want to get the data from a Microsoft Access DB. (READ ONLY, So I'll only use SELECT commands).
using System.Collections.Generic;
using Telephone_Directory_2010.Model;
namespace Telephone_Directory_2010.DataAccess
{
public class EmployeeRepository
{
readonly List<Employee> _employees;
public EmployeeRepository()
{
if (_employees == null)
{
_employees = new List<Employee>();
}
_employees.Add(Employee.CreateEmployee("Student One", "IT201", "Information Technology", "IT4207", "Building1", "Room650"));
_employees.Add(Employee.CreateEmployee("Student Two", "IT201", "Information Technology", "IT4207", "Building1", "Room650"));
_employees.Add(Employee.CreateEmployee("Student Three", "IT201", "Information Technology", "IT4207", "Building1", "Room650"));
}
public List<Employee> GetEmployees()
{
return new List<Employee>(_employees);
}
}
}
I found another example where an Access DB is used but it doesn't comply with MVVM. So I was trying to figure out how to add the DB file to the project, how to wire it up and bind it to a listbox (i'm not that far yet). Below is my modified file
using System.Collections.Generic;
using Telephone_Directory_2010.Model;
// integrating new code with working code
using Telephone_Directory_2010.telephone2010DataSetTableAdapters;
using System.Windows.Data;
namespace Telephone_Directory_2010.DataAccess
{
public class EmployeeRepository
{
readonly List<Employee> _employees;
// start
// integrating new code with working code
private telephone2010DataSet.telephone2010DataTable employeeTable;
private CollectionView dataView;
internal CollectionView DataView
{
get
{
if (dataView == null)
{
dataView = (CollectionView) CollectionViewSource.GetDefaultView(this.DataContext);
}
return dataView;
}
}
public EmployeeRepository()
{
if (_employees == null)
{
_employees = new List<Employee>();
}
telephone2010TableAdapter employeeTableAdapter = new telephone2010TableAdapter();
employeeTable = employeeTableAdapter.GetData();
this.DataContext = employeeTable;
}
public List<Employee> GetEmployees()
{
return new List<Employee>(_employees);
}
}
}
I get the following error messages when building
Error 1 'Telephone_Directory_2010.DataAccess.EmployeeRepository' does not contain a definition for 'DataContext' and no extension method 'DataContext' accepting a first argument of type 'Telephone_Directory_2010.DataAccess.EmployeeRepository' could be found (are you missing a using directive or an assembly reference?)
