ItemDoubleClick Event

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

Syntax

Visual Basic

'Declaration
 
Public Event ItemDoubleClick As ItemDoubleClickEventHandler

C#

public event ItemDoubleClickEventHandler ItemDoubleClick

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:

Visual Basic

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinListView

    Private Sub ultraListView1_ItemDoubleClick(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinListView.ItemDoubleClickEventArgs) Handles ultraListView1.ItemDoubleClick

        If e.Item.Tag.GetType() Is GetType(System.IO.FileInfo) Then

            Dim fileInfo As FileInfo = CType(e.Item.Tag, System.IO.FileInfo)
            If Not fileInfo Is Nothing AndAlso fileInfo.Extension.ToLower() = ".txt" Then
                Dim psi As ProcessStartInfo = New ProcessStartInfo("notepad.exe", fileInfo.FullName)
                Process.Start(psi)
            End If
