Examples

The following example shows how to use the NewEditIndex property to retrieve the ListViewItem object that is being edited. This code example is part of a larger example provided for the ListViewEditEventArgs class.

void ProductsListView_ItemEditing(Object sender, ListViewEditEventArgs e)
{
  ListViewItem item = ProductsListView.Items[e.NewEditIndex];
  Label dateLabel = (Label)item.FindControl("DiscontinuedDateLabel");
  
  if (String.IsNullOrEmpty(dateLabel.Text))
    return;
  
  //Verify if the item is discontinued.
  DateTime discontinuedDate = DateTime.Parse(dateLabel.Text);
  if (discontinuedDate < DateTime.Now)
  {
    Message.Text = "You cannot edit a discontinued item.";
    e.Cancel = true;
    ProductsListView.SelectedIndex = -1;
  }       
}

Sub ProductsListView_ItemEditing(ByVal sender As Object, ByVal e As ListViewEditEventArgs)
  Dim item As ListViewItem = ProductsListView.Items(e.NewEditIndex)
  Dim dateLabel As Label = CType(item.FindControl("DiscontinuedDateLabel"), Label)
    
  If String.IsNullOrEmpty(dateLabel.Text) Then _
    Return
    
  'Verify if the item is discontinued.
  Dim discontinuedDate As DateTime = DateTime.Parse(dateLabel.Text)
  If discontinuedDate < DateTime.Now Then
    Message.Text = "You cannot edit a discontinued item."
    e.Cancel = True
    ProductsListView.SelectedIndex = -1
  End If
End Sub

Remarks

Use the NewEditIndex property to determine the index of the item that is being edited. The item index is often used to retrieve this item from the Items collection of the ListView control, which enables you to access the item's properties.
