/*[email protected]: The below event handler was blindly incrementing or decrementing values.

* Say after loading the grid with one hidden row, user sets the RowsCount of the same grid to 0.
* Making the grid empty. At that time this event is not triggered and m_totalHiddenRows value will not be decremented.
* Now if you load the grid again with 1 hidden row, this will get incremented to 2. Which is wrong*/
