I have a dbgrid on a form, with the data source set to a TSQLQuery. The database is MySQL 5.6
But I cannot edit the cells. I can double-click in the cell, and it LOOKS like editing is allowed - highlight part of the contents,. But typing has no effect.
The properties at this stage are the default - I recreated the grid and left all the properties alone. In particular, AutoEdit is true, as is the option dgEditing.
I looked at the example project 'dblookup' and the grids there seem to have been configured as I have my ine.
What stupid mistake am I making?
