Description: Runs after the user selects a RadioGroup item and the connected entry has received the new value.
Desktop execution: The click follows the normal UpdateValue path. After value write-back and component notification, the DBForm recalculates, executes OnSelect, and recalculates a second time when a valid formula exists. The second recalculation also occurs if formula calculation reports an error.
Web execution: The click writes the new value directly to EntryData.CurValue, marks the component changed, calls UpdateValue, recalculates once, and then executes OnSelect. There is no second recalculation after the formula. Because the value was written before UpdateValue, its normal change-notification path can be skipped.
Arguments: There are no event-specific arguments. The custom executor does not populate Argument_EventName, Argument_SenderName or Argument_SenderID. The connected entry already contains the selected value.
Result: Any value assigned to Result is ignored. Use the formula for side effects or entry assignments.
Availability: Desktop and web.
Example:
ShowMessage("A new radio item was selected");
