Leave Page = Leave Changes

[John]

We would like a function that warns before leaving a page with changes. Is there a way to do this through the Kendo Data? Can we check for dirty data?

Thanks

Hi John,

Generally speaking there is no such method. To achieve it you will need keep track of any changes made to the Grid. You can hook functions to the 'remove' and 'edit' events which turn on global flags which indicate if you have made any changes.
Also if you want to check if a partucular object has any changes you can use the following dataSource method.

$('#grid').data('kendoGrid').dataSource.get(7).hasChanges()

where 7 is the index of your item in the dataSource.

Kind regards,
