Hi Kendo Team,
I'm iterating the collection dataSource.data() and I want to know if a data item of this collection is deleted or not.
There is isNew() method that tells you if the user created a new item, but how can i know if an item of the dataSource was deleted by the user? Is there any IsDeleted() method ?
Something like:
for (var i= 0; i < dataSource.data().length; i++){
   if (!dataSource.data()[i].isDeleted()){  
        // Do whatever
   }
}
Kind regards,
Oscar.

Hi Oscar,

There is not isDeleted() property of the dataSource, as the items are directly removed from the dataSource, and no flag is set. The items are completely detached from the dataSource and not methods can be executed on them.

Hi Kiril,
Are you sure? I forgot to say I'm using a grid in batch mode edit and I think deleted rows are actually removed from datasource only when methd sync is executed.

Kind regards.

Hello Oscar,

You can test this, by searching for the item after you have deleted it. Here is a video that I made, showing it:
