My requirement is below:

I have 3 types event status : New, InProgress, Completed.

I have configured grid, in that grid column is status count, So here i need to display the records count in status column based on the status .

For example, i have 4 records those 4 records event status count i need to display : like event start time the status is New so i need to display 0/4, after some time agent will run background and changed the event status to In Progress which means suppose 2 records status changed, So in that case i need to display 2/4, after some time Event status is completed in that case need to display 4/4..

Attached requirement screenshots .

above scenario, So can any help on the requirement how implement?

Thanks in Advance.
