Count of selected rows.

ArunRahul

In my code I am using two custom(not table tools provided) buttons which selects and deselects all the rows in table.I am calling fnSelectAll() and fnSelectNone() respectively for those button click callbacks. Also I can induvidually select multiple rows in the table.
Is there a way/technique through which I can get the count of selected rows ? Could any one help me on this ?
I tried to implement it with one variable which gets incremented when I select any row (I am incrementing the count at fnRowSelected callback) and gets decrement when I de-select any row (I am decrementing the count at fnRowDeselected callback). As I am implementing custom buttons to select and deselect all I tried the same in those button click callbacks also . But it didn't work.

Use `fnGetSelected().length` - http://datatables.net/extras/tabletools/api#fnGetSelected

But I have to call it multiple times at multiple places. Would it affect performance?

Unless you have tens of thousands of selected rows, I doubt you'd ever notice. But the only way to be certain is to try it and profile it.
