Making a type-ssafe collection class bindable..?

[Merrion]

I have a usercontrol and one of its members is a type safe collection (inherited from CollectionBase.DictionaryBase).

Now I want this collection to be bindable (read-only) to a datagrid. I have added the attribute <Bindable()> to the property and implemented IListSource in the control and returned this list from GetList() overloaded function but it doesnt show up in the datagrids bindings.

What step(s) am I missing?

Thanks in advance,
Duncan

Hmm - maybe I should replace IListSource with IBindingList...shall check when I get home.

OK - I was on the wrong track with IListSource - It should have been IBindableList...now the Datagrid binds to the list but it doesnt know anything about the data type within the collection - how do I do that part?

Implement the Add Sub, Create Method, and Item Property with youre datatype in mind. So, for the Item property, youll do something like this:

Default Property Item(ByVal key As String) As MySpecificDataType
  Get
      Return CType(Dictionary.Item(key), MySpecificDataType)
  End Get
  Set(ByVal Value as MySpecificDataType)
      Dictionary.Item(key) = Value
   End Set
End Property
