Repeater.OnDataBinding Method (EventArgs)

 

This API supports the product infrastructure and is not intended to be used directly from your code.

Raises the DataBinding event.

Namespace:   System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

protected override void OnDataBinding(
	EventArgs e
)

Parameters

e
Type: System.EventArgs

An EventArgs object that contains the event data.

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.
