difference between data-show and data-init

[Justin]

what is the difference between data-show and data-init?  and when should you use each one?

[Alexander Valchev]

Hi Justin,

The data-init will fire once, after the view and its child widgets are initialized, while the data-show will fire every time when the view becomes visible.
The init event is suitable for actions that should be done only once, right after the initialization of the view (for example - creating a widget). The show event is appropriate for a code that you want to be executed after each show of the view.
For convenience I prepared a small example that shows the event usage in action.

Thanks for the reply,

my question was in response to not having access to the e.view.params from the data-init event while i do have access to e.view.params from from the data-show event.  Is this the correct behavior?

Hi,

Yes, this is the expected behavior, as described in our documentation.

Note that data-show executes every time you call alert( ) , Phonegap's notification.confirm ( ) and notification.alert ( ) on a mobile device. This is a very strange behaviour

Hello Abdul,

Indeed it is - we have not received reports of such behavior so far. Is it possible for you to open a ticket with a a sample that reproduces it? We will take a look.

Yes Petyo, I have raised this issue via Telerik Support. Please Search for "Method Bonded with data-show executes every time alert ( ) function is called " and you will find the code to reproduce the problem,
Thanks
