Fired when the data source makes a remote service request.
However, when the DataSource sorting is set to local, the event "requestStart" is still being fired causing us bugs.
Could you please elaborate on your exact requirement, so we can suggest an alternative solution for it.
Our case is that we have local sorting and remote paging. So when we enter requestStart, we check if the grid has unsaved changes and ask the user if he wants to save. however we don't want to do that wh the user sorts because the sorting is local. And since both requests are read requests and can't be differentiated in the requestStart method then the message will be shown for the user anyway. Using request end is not an option in this case because it would be too late.
