Hi,

I have a user control, which is a bunch of textboxes and dropdowns.  I
also have a bindingsource component, to which an object is bound.
Also, an ErrorProvider component as well.

The bound object correctly implements IDataErrorInfo as well.  When
changing a property, the data is validated and the methods to do the
validation do run, but the ErrorProvider never shows its icon.

Any ideas?

Thanks
Andy
