To: [EMAIL PROTECTED]
Well, the first thing is that you are really not binding the
ICollection to the datagrid, you are binding the objects in the
Collection. So the first thing you need to know is that when you use
DataBinding on a datagrid or any other bindable object is that it will
only bind to Properties instead of Fields. Here is the difference...
Public Class EmployeeBiz
public EmployeeName As String
public EmployeeZip As String
End Class
The above is using "Fields" because the data members are public.
Below is an example of using Properties.
Public Class EmployeeBiz
Private _employeeName As String
Private _employeeZip As String
Public Property EmployeeName as String
Get
Return _employeeName
End Get
Set
_employeeName = value
End Set
End Property
Public Property EmployeeZip as String
Get
Return _employeeZip
End Get
Set
_employeeZip = value
End Set
End Property
End Class
The above class with Public Properties will bind correctly, but the
one with Fields will not.
It is actually amazing that I wrote some VB code.
HTH.
