Repeater.OnDataBinding Method
.NET Framework 2.0
This method supports the .NET Framework infrastructure and is not intended to be used directly from your code.
Raises the DataBinding event.
Namespace: System.Web.UI.WebControlsAssembly: System.Web (in system.web.dll)
The following code examples demonstrate how to override the OnDataBinding method in a custom server control so that if the event argument is a command type, the Repeater control always calls the OnItemCommand and bubbles up the event, or returns false and cancels the event.
