VSFlexGrid FindRow functionality question

Greetings,

I'm examining pre-written code that has a VSflexgrid component where the values have been populated at a cell level with textmatrix command and has nothing set at .rowdata level.

Using the .findrow function am I right in thinking this will not allow all the rows and columns to be searched for a specific text string?

Only if I search for the specific column does it seem to find the value e.g.
In code it looks like from the comments that it expects all rows and columns (apart from the header row) to be searched, can someone please clarify if this is achievable, thanks?

Cheers
Rob
