IBindingList with dynamic columns

[Dante]

Hi Folks,

I have a datagrid that could be bound to an IBindingList. Currently I
don't get it how the mapping is made between the class and the grid. As
far as I got I have a class with some public properties that will be
mapped automatically by the grid to be used as columns.

Now I have the situation that at runtime it is possible to add some
other objects to that class with a variable amount of entries which
should be shown as columns. Because their can vary I have no properties
for them and have to access them via functions. But how do I get the
grid to understand that?

Thx in advance

You've to implement ITypedList. ITypedList allows you to return
propertydescriptors for the properties you want to expose for the
objects IN your collection/list. See for an explanation:
