Question

I can set query for the OnDemandGrid after loading JSON from server and it filters locally the grid for me without sending any request to server

gridPol.set("query", PostID: '339635');
gridPol.refresh()

I alos want to add a function to reset grid to the fist state Is there any option?

Answer 1

It was so easy

if set null in query then grid changes to first step

gridPol.set("query", null);
gridPol.refresh()
