How to bind dynamic data object with SfDataGrid?

 
SfDataGrid dataGrid;
dataGrid = new SfDataGrid(this);
employeeCollection = new EmployeeCollection();
dataGrid.ItemsSource = employeeCollection.EmployeeDetails;
 

public class EmployeeCollection
{
       
Random random = new Random();
      
public EmployeeCollection()
{
    EmployeeDetails = GetEmployeesDetails_Dynamic(200);
}
 
#region ItemsSource
 
private ObservableCollection<dynamic> _employeeDetails;
public ObservableCollection<dynamic> EmployeeDetails
{
    get
    {
        return _employeeDetails;
    }
    set
    {
        _employeeDetails = value;
        RaisePropertyChanged("EmployeeDetails");
    }
}
 
#endregion
 
// Dynamic DataSource
 
public ObservableCollection<dynamic> GetEmployeesDetails_Dynamic(int count)
{
    var employees = new ObservableCollection<dynamic>();
    for (int i = 1; i < count; i++)
    {
        employees.Add(GetDynamicEmployee(i));
    }
    return employees;
}
 
// Dynamic Property
public dynamic GetDynamicEmployee(int i)
{
    dynamic employee = new ExpandoObject();
    employee.EmployeeName = employeeName[random.Next(14)];
    employee.EmployeeID = i;
    employee.ContactID = i + 100;
    return employee;
}
 
string[] employeeName = new string[]
{
    "Sean Jacobson",
    "Phyllis Allen",
    "Marvin Allen",
    "Michael Allen",
    "Cecil Allison",
