That works fine (you can obviously check it :) 2 grids cannot be active at the same time. As soon as one grid gets focus it's AfterRowColChange() event fires and updates the form property with the correct value.

nGridRecno can be a grid property (or, obviously, GridHighlighter property :).
But nothing is wrong if it is a form property, for example, if the row highlighting was the feature added at the last moment.
