Telerik.Web.UI.GridCommandEventArgs OnCommand Property

Note

To get or set property values for client API properties, you must call property accessor methods that are named with the get_ and set_ prefixes. For example, to get or set a value for a property such as cancel, you call the get_cancel or set_cancel.

This event 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. The event can be intercepted in order to perform a certain operation in the grid via web service or to detect what type of command is raised on the client.
