You have to go back to the shp file contents, and the OMGraphicList
created from the geometry. The order of the contents of the shp and
dbf files are the same and correspond to one another, so you find out
the location of the attribute by going to the geometry.

The EsriPlugIn kind of does this, in the mouse clicking code where it
takes an OMGraphic (EsriGraphic), asks it for the Integer index into
the dbf file to highlight the table entry. I think there is some
action to handle tooltips, too, that you can build from.

Hope this helps,
