list of triggers


where can i find the list of triggers i can use?


i am looking for something to trigger an event when something is shown (i don’t mean visible i mean when there is nothing on top of it) to be able to reload the page when the user scrolls up and he reaches the top of the scroll (facebook style)):


    <Panel Height="10 Alignment="Top">
        <Text Value="one" TextAlignment="Center"/>

    <Panel Height="10 Alignment="Top" Margin="0,10,0,0">
        <Text Value="two" TextAlignment="Center"/>

        <!-- I want something to happen when user scrolls up when -->
        <!-- he is on the top so those 2 panels become "visible" -->


I found the list… but still don’t know if it’s possible to do what i want:

and finally i found an example :slight_smile:
