virtual int FindCore(
	PropertyDescriptor^ prop,
	Object^ key
)

The PropertyDescriptor to search for.

The value of property to match.

Exception Condition
NotSupportedException

FindCore is not overridden in a derived class.

The BindingList<T> class does not provide a base implementation of searching, and so FindCore always throws a NotSupportedException by default. To enable searching, derive from BindingList<T> and perform the following tasks:

The following code example demonstrates how to use the FindCore member.
