How to set time formate in datagridview cell in c#

Question

Hai,

 

In my project I need to enter the machine running time , Total running time and Idle time in datgridview cells .

 

Here I want to set the time format in datgridview cells, which means I just enter only the number ,system will separate the hour and minutes.

 

For an example:

I am just typing only the numbers 1100,1200 like vise.

starttime	endtime	totaltime	idle time
11:00AM	12:00PM	13:00	02:00

How can I do this.  Here total time will calculate automatically based on the start and end time . How can I do this , please anybody help this question I need to finish it quickly.

 

Thanks in advance.
