Please help me to make clear the code logic here...

I print the log in A,B for make clear the logic and then see, at the beginning , A not did anything ,while B did a time. Before this do, the value in A is true,B is false. Now A should be false too , yes? This means when A be false,the "move"and “change” will act when I click preview. So i alter A the value be false, ,but after preview , A don’t work still. so please help

Please post your code as Text so that it is easier to help.

just the example “PageControl” . It means not bug just i cann’t see it clearly…

When the preview start slideOut.Value is initialized to true. When the Info is activated it will change slideOut.Value is changed to false. The ActivatingAnimation does not have a value it will just trigger.

you mean while slideOut.Value= false ,the trigger will be called? but ,I set slideOut.Value be false at the beginning ,why the move and change don’t work still?

Now i see ,thanks…
