In the demo here : http://demos.telerik.com/kendo-ui/grid/virtualization-remote-data and in other tests I have done in my app, it seems that the request to load data from the remote datasource is done two times (or sometimes just one time as expected).
The problem with this behavior is that my app has to perform a big query in the database two times instead of one, which is bad for performance.
Is there any reason why this is done this way or is this a bug ?
I have tested on OSX with Safari, Firefox Dev and Opera Dev.
Thanks for your help.
