How do you stop scrolling to top when grid store is reloaded

Question

I have an app that uses ExtJS 3.3.0. It uses an EditorGridPanel in which after the store is reloaded - I would like it to preserve the scroll position of the grid rather than sending it back up to the top.

Because this is an earlier version of ExtJS - this DOES NOT work:

viewConfig: {
   preserveScrollOnRefresh: true
}

So far the only thing I can come up with is to save the position of the scroll bar prior to loading - and then reset the position once the reload is complete.

I can get as far as saving the position:

var scrollPos;

bodyscroll: function(sl, st) {
    scrollPos = st;
},

However I can't figure out how to set the position afterwards.

Any suggestions?

Thanks in advance.

There might be multiple ways to do this but one way is to use the scroller element, which is accessible through the grid's gridview. See fiddle here: Grid scoll save/restore.

To get scroll value (which you've already got figured out):

var top = grid.getView().scroller.getScroll().top;

To restore:

grid.getView().scroller.scrollTo('top',top);
