Hi Waruni,

Please take a look at the Flexible Server-side Validation help topic and demo to see how to add validator to the EditItemTemplate of a GridTemplateColumn. 
You can find a sample of CompareValidator validating the dates picked by the user ensuring that end time value is greater than the start time here.

I hope you find this useful.
