Esempio

Nell'esempio di codice seguente viene illustrato come usare l'oggetto ListCommandEventArgs per modificare lo stato delle attività in un elenco quando viene fatto clic sull'elemento. Questo esempio fa parte di un esempio più grande per la List panoramica.

private void Status_ItemCommand(object sender, 
    ListCommandEventArgs e)
{
    const string spec = "You now have {0} " + 
        "tasks done, {1} tasks scheduled, and " +
        "{2} tasks pending.";

    // Move selection to next status toward 'done'
    switch (e.ListItem.Value)
    {
        case "scheduled":
            schedCount -= 1;
            pendCount += 1;
            e.ListItem.Value = "pending";
            break;
        case "pending":
            pendCount -= 1;
            doneCount += 1;
            e.ListItem.Value = "done";
            break;
    }

    // Show the status of the current task
    Label1.Text = e.ListItem.Text + " is " +
        e.ListItem.Value;

    // Show current selection counts
    Label2.Text = String.Format(spec, doneCount, 
        schedCount, pendCount);
}

Private Sub Status_ItemCommand(ByVal sender As Object, _
    ByVal e As ListCommandEventArgs)

    Const spec As String = "You now have {0} tasks done, {1} " & _
        "tasks scheduled, and {2} tasks pending."

    ' Move selection to next status toward 'done'
    Select Case e.ListItem.Value
        Case "scheduled"
            schedCount -= 1
            pendCount += 1
            e.ListItem.Value = "pending"
        Case "pending"
            pendCount -= 1
            doneCount += 1
            e.ListItem.Value = "done"
            
    End Select

    ' Show the status of the current task
    Label1.Text = e.ListItem.Text & " is " & _
        e.ListItem.Value

    ' Show current selection counts
    Label2.Text = String.Format(spec, doneCount, _
        schedCount, pendCount)
End Sub
