Make rows mandatory

created 12 years ago

Is there a qucik way to force a user to "tick"/select treelist rows in a particular order?
E.g. instead of being able to select/tick the box in ROW 1, ROW5 & ROW8, a user has to select ROW2, ROW3 and ROW4 to get to ROW5.

I've got a treelsit which is effectively a sort of tasklist. Some tasks are mandatory and need to be "ticked" before the next task can commence.
The data I'm using to build this treelist already has a hidden column called MANDATORY which contains a 0 or a 1 to determine if a row is mandatory (1 being mandatory)

Thanks

To achieve this goal I suggest you handle the TreeList.BeforeCheckNode event to determine whether or not a particular node can be checked or unchecked.
