Hello Rahul,

You can attach the client event OnCommand. This will be raised for each grid command which is about to be triggered (sorting, paging, filtering, editing, etc.) before postback/ajax request except hierarchy/grouping expand/collapse action.

aspx:

<ClientSettings>
              <ClientEvents OnCommand="RaiseCommand" />
<ClientSettings>

JavaScript:

function RaiseCommand(sender, args)
{
       if (args.get_commandName() == "CancelUpdate")//check for the condition
      {
           //your code here
       }
   }

 Also refer the following documentation for more on this:
OnCommand

Thanks,
Shinu.
