Is it possible to segregate the difference between Check All and Normal select.

Is it possible to segregate the difference between Check All and Normal select.

I am having two rows in the Grid. Now whenever I select 2nd row, automatically select all is also getting checked.
And my requirement is to differentiate these two event. I want to process further on the basis of this.

If Rows are selected by clicking on Select all then no need to process.
And if second row is selected after selecting the first then first will be unchecked automatically and second will be checked.
It is like a Radio Button. But in Grid layout it is populating with check box only. I have gone thru all the recipe and tutorial but not found any thing concrete to get it solved.

Could any please suggest. Thanks.
