remember after refresh selected row in extjs grid

Question

I have a problem. I use extjs grid. This grid will be refreshed every seconds.

I refresh with this function:

ND.refresh =

The straightforward solution is just save somewhere in js index of selected row. Then after reload you could easily select this row by index using grid's selection model.

Get selection model: http://docs.sencha.com/ext-js/4-0/#!/api/Ext.grid.Panel-method-getSelectionModel

var selectionModel = grid.getSelectionModel()

Get selected rows: http://docs.sencha.com/ext-js/4-0/#!/api/Ext.selection.Model-method-getSelection

var selection = selectionModel.getSelection()

Set selected row back: http://docs.sencha.com/ext-js/4-0/#!/api/Ext.selection.Model-method-select

selectionModel.select(selection)
