Hello Sandeep,

I`m not familiar with your scenario and I don`t know what is your final goals, but I think that our UltraGrid has enough events that you could use it.  Nevertheless, if you thik that you need to implement your custom event, then you could choose one of these approaches.

Option 1: You could use the source code of our controls (you could find the source code at: Infragistics.com -> Account -> My Keys and Downloads -> Source Code) and implement your custom event. After that you could build your custom assemblies

Option 2: You could create your own Grid which inherite our UltraGrid and implement your custom event. I made small sample for you using this approach. Please take a look at the attached sample and video file for more details and if you have any questions, feel free to write us.

Regards
