DrillthroughEventHandler Delegate 

Represents the method that will handle the Drillthrough event of a ReportViewer.

Namespace: Microsoft.Reporting.WebForms
Assembly: Microsoft.ReportViewer.WebForms (in microsoft.reportviewer.webforms.dll)

public delegate void DrillthroughEventHandler (
	Object sender,
	DrillthroughEventArgs e
)
/** @delegate */
public delegate void DrillthroughEventHandler (
	Object sender, 
	DrillthroughEventArgs e
)
JScript supports the use of delegates, but not the declaration of new ones.

Parameters

sender

The object that raised the event.

e

A DrillthroughEventArgs object that contains the event data.

You must supply a data source for any drillthrough reports that are referenced by the main report. To do this, you must supply an event handler for the drillthrough event.

For more information about handling events, see Consuming Events.

Please see the Drillthrough method of the ReportViewer class for an example.
