How to detect that last row is reached

Is it possible to detect when the last row is reached?

I want to populate the grid with new rows when key-down is pressed and the last row is already selected (paging).

You need to set a handler for the "selectionChanged" action, retrieve an index of the selected row ("selection/index") and compare with the index of the last row.

function myAction(){
var index = this.getProperty("selection/index");
var count = this.getProperty("row/count");
var lastRow = this.getProperty("row/value", count-1);
if (index == lastRow){
// request more data

obj.setAction("selectionChanged", myAction);

Unfortunately I just found a bug - selection/index is set only after selectionChanged action :-( so the example above will not work until I fix that in 0.2.5 (or you can run it with window.setTimeout)

I had to set custom row-id's which are identical with the row-id's (keys) in my database.
In this case "this.getProperty("selection/index")" doesn' t return the rownumber of the grid - it returns my database-keys.
In my opinion there shouldn't be a "selectionChanged"-Event fired when the last row is reached and "key-down" is pressed. I'd like to have something lika a "lastRowReached"-Event and "firstRowReached"-Event.
