RadControls for ASP.NET AJAX

In some specific cases you may want to raise command events (like Edit/Update/Delete/Filter/Page/etc.) in code rather than clicking buttons/filter menu items in the grid. For such type of situations Telerik RadGrid exposes the FireCommandEvent(eventName, eventArgs) method which can be called for all items which extend the GridItem type (GridDataItem, GridFilteringItem, etc.).

The table below explains the parameters which you can pass to that method to fire corresponding commands:
