Repeater.OnBubbleEvent Method
.NET Framework 3.0
This method supports the .NET Framework infrastructure and is not intended to be used directly from your code.
Raises the ItemCommand event if the EventArgs parameter is an instance of RepeaterCommandEventArgs.
Namespace: System.Web.UI.WebControlsAssembly: System.Web (in system.web.dll)
protected boolean OnBubbleEvent ( Object sender, EventArgs e )
protected override function OnBubbleEvent ( sender : Object, e : EventArgs ) : boolean
Not applicable.
Parameters
- sender
The source of the event.
- e
An EventArgs object that contains the event data.
Return Value
true if the ItemCommand was raised, otherwise false.The following code example demonstrates 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.
