Hello,

The UniGrid control provides OnAction handler that accepts two parameters and can be used to handle performed actions:
string actionName - is used to identify which action raised the event
object actionArgument - is used to pass the value of a data source column from the UniGrid row for which the action was used

I would like to point you to the following section of Controls guide to get more information about UniGrid:
Unigrid overview


Best regards,
Michal Legen
