TemplatePagerField.PagerCommand Event
Visual Studio 2010
Occurs when a button is clicked in a TemplatePagerField object.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
The PagerCommand event is raised when a button is clicked in a TemplatePagerField object. This enables you to perform a custom routine whenever this event occurs.
The following example shows how to use the PagerCommand event to perform a different action depending on which button was clicked in a TemplatePagerField object.
