1. I want to clear this highlight cell which gets selected on click of that cell and prevent further events from that cell.

Eg-1: On click of some button in the screen, I want to clear all the selected cells.

Eg-2 :  I have a simple counting function that increase the count on cell click. For the first time selection of the cell it works, but again selecting the same cell , it doen't work., may be the cell is already selected, so how can I clear that cell selection or prevent the cell selection part from the whole grid in a way it should not affect the counting function.
