Description
This sample shows what the DisableServerRead property works for.
When it is set to True, all the items will be transferred to the client side. Sorting, paging or filtering will be done in the client side.
And the text like "Loading..." is not shown for loading the data when the scrollbar scrolls.
Otherwise, sorting, paging or filtering will be done in server side. And sometimes the "Loading..." text will be shown.
