Noob question

Investigating further, it seems that
MyClass2_BindingSource.SupportsFiltering, which is weird
since I DID try
BindingList<T> in addition to List<T>.  The way
I see it, it should
work...

Any ideas yet?

Ok, I've read the relevant parts of Chris Sells' book, have
a slightly
more involved question...

I've created two classes that expose some properties.  I've
declared two
List<T>s based on them:

List<MyClass1> MyList1 ...
List<MyClass2> MyList2 ...

I then used the Data Source Wizard to add both of them as
Data Sources
in my project and created 2 DataGridViews based on those
sources (drag
and drop from Data Sources window), which automatically
creates 2
BindingSources too.  The *DESIGNER* initiliazes these with
code similar
to this:

MyClass1_BindingSource.DataSource = typeof(MyClass1)
MyClass2_BindingSource.DataSource = typeof(MyClass2)

Of course I only used the wizard as a convenience (creating
those
columns is a PITA), but I want it to use MY lists, not some
internal
List object, so I assign:

MyClass1_BindingSource.DataSource = MyList1
MyClass2_BindingSource.DataSource = MyList2

Which seems to work fine.

*NOW*, my problem is I want these browses to work as
Parent-Child.  On
the MyClass1_BindingSource.CurrentItemChanged event, I am
checking the
selected item (contains what I expect it contain), then I
set
MyClass2_BindingSource.Filter accordingly.

I've verified the filter is changing, to the value I want,
but the
second Grid is NOT reflecting any change in the filter.

Whew...so what stupid noob mistake am I making?  I tried
using
BindingList<T> instead of List<T> but no
difference.

Many thanks,

Chris
