ASP.NET - How to check whether system date matched with a bound column in gridview

Hello Experts,
 
I have a gridview consisting of columns like UserID,TaskID,ReminderDate,Task,TaskType,TaskStatus
 

 

How to check whether datetime in ReminderDate column is matched with system Date.
 
Please guide me.....

Get its date part and look them if the date frequency is in the current scale +1 day > DateTime.Now >- 1 day (DateTime.Now.AddDays(-1))
This will give you 12pm to 12pm scale
If you dont want to use this you must look the time span when you get the current time as a TimeSpan 
1- TimeSpan currTime = DateTime.Now; or .Time (i dont remember all)
2- Get you DB fields time as a TimeSpan
and compare them startTime <= currTime <= endTime
