>I've coded a class where a single grid serves as a lookup grid for multiple txtboxes. To do its job right the grid has to recognize when the "client" txtbox changes.

There is no way to differentiate between objects that I know of but you can pass additional information to define a particular textbox. In addition to passing THIS, pass the ActiveRow and ActiveColumn properties of the Grid to the method.

HTH.
