ItemDoubleClick Event

Occurs after the value of the CheckState property of an UltraListViewItem has been changed.

Syntax

Visual Basic

public event ItemDoubleClickEventHandler ItemDoubleClick

C#

'Declaration
 
Public Event ItemDoubleClick As ItemDoubleClickEventHandler

 

Event Data

The event handler receives an argument of type ItemDoubleClickEventArgs containing data related to this event. The following ItemDoubleClickEventArgs properties provide information specific to this event.

Property	Description
Item (Inherited from Infragistics.Win.UltraWinListView.ItemEventArgs)	Returns the UltraListViewItem with which this instance is associated.

Remarks

The UltraListView control does not expose an 'ItemClick' event; use the ItemActivated event if your application requires a notification when the end user navigates to a different UltraListViewItem.

Example

The following code sample demonstrates how the UltraListView's ItemDoubleClick event can be handled to perform an action, such as opening a file, when an UltraListViewItem is double-clicked:
