ChangeEventPolicy in iterator


By default the iterator will refresh when the user first enters the page. But sometimes you need to control the refresh action of the iterator for some reason.

There are three optional iterator properties Refresh, RefreshCondition,and RefreshAfter which will control the refreshing of the iterator accordingly.

ChangeEventPolicy property in the iterator controls the behavior of the refresh action. It has three properties

none – by default, iterator refreshes according to the refreshcondition specified

push – asynchronous data change in the model layer will be pushed automatically.. used in BAM and Active Data Components

ppr – this will decide on when to refreshes the components bound to the iterator. If the current row of the iterator is changed and when the ppr is occurred the iterator will get refreshed to reflect the changed data
