It is the object which manages the overall properties about grid display.
It is used as GridBase.displayOptions property. Since it is created internally when initializing grid, you do not need to directly create this class object.
grid.setOptions({
display: {
selectStyle: "rows",
wheelDelta: 5,
fixedColumnCount: 2
}
});
grid.setDisplayOptions({
columnMovable: true,
columnResizable: true,
fixedRowCount: 2
});
