I am using TDBAdvGrid component to display data from database table.
It is showing 4 columns - Group, Short Description, Long Description, Image to DBAdvGrid from table.

DBAdvGrid.PageMode = true
The option goEditing is set to true in DBAdvGrid.Options.
ReadOnly property of all columns of DBAdvGrid is set to False.

Despite of it, only for the first column(Group) of the DBAdvGrid is allowing inplace editing. All other columns inplace editing is not working.
