Gentlefolk,

This is more philosophical than technical and I am looking for ideas
on what I should do in the following situation:

A DBGrid with most of the columns set to READONLY to display
information and two columns where data can be input.

If the user clicks on a cell in a READONLY column this cell is
highlighted giving the user the idea that the cell is accessible.

What should I do?

In the "OnClick" code simply set the colour of the cell to the
background colour therefore ignoring the 'click'.

In the "OnClick" code display a error message to the user.

In the "OnClick" code set the  "SelectedIndex" to a 'Readable" column
in the same row.

Something else?

Any help appreciated, Ian.

There is OnDrawCell event in TStringGrid, in a handler of that you can
paint whatever you like. In DBGrid there is OnDrawColumnCell. Try
that.
