Hi there: I would like to check numerical data on a StringGrid. Instead of checking the whole grid in one operation, I'm thinking in checking while editing. That is, once you edit a cell and "leave it", the previous value will automatically re-appear if the data entered is incorrect (a conversion error detected). In which order should I use the OnGetEditText, OnSetEditText or any others necessary events to achieve this? Does any of the examples provided with Delphi shows this? And, is there a place on the web with code examples for such common tasks? Thanks in advance.
