Hello, I have a Table control directly bound to a data file.
I want to be able to make some validations before the user input is sent to the database.
I'm struggling to understand what I should do and where.

Can you help me?

With high likliness you want to do somthing in the Whenever Modifying even
or in the Deactivate Event, maybe you want to save some state while activating

// In Entry of the Column
vSavedVal = MySelf


// In whenever modifying Control
IF MySelf = "Test" THEN
Info("I don't like that value, resetting");
MySelf = vSavedVal
END

//Exit from a row of <TableControl>

//Sample avoid same Values on two Fields
IF MySelf.InputInProgress() THEN
IF COL_Field1 = COL_Field2 THEN
Error("Fields cannot have the same Value")
ReturnToCapture()
END
END
