 ## Examples
- The following example shows <xref:System.Web.UI.WebControls.Label> controls that are contained in a <xref:System.Web.UI.WebControls.ListView> control. On the <xref:System.Web.UI.WebControls.ListView> control, the <xref:System.Web.UI.Control.ClientIDMode%2A> property is set to <xref:System.Web.UI.ClientIDMode.Predictable> and the <xref:System.Web.UI.WebControls.ListView.ClientIDRowSuffix%2A> property is set to `ProductID`. In the rendered HTML, this creates three `span` elements that correspond to three `ProductIDLabel` controls. When the page runs, the `id` attributes for the `span` elements are set to the following values:
-
--   `ListView1_ProductIDLabel_1`
-
--   `ListView1_ProductIDLabel_34`
 
--   `ListView1_ProductIDLabel_43`

 ## Examples
  The following example creates an event, named `Click`, that adds and removes handlers from the control's <xref:System.ComponentModel.EventHandlerList> collection when the event is called from a page.
 
- **Note** This example optimizes how a control adds and removes events from the list of them that the control maintains. If you create custom control and want to define an event, use code similar to this. This technique can be used in C#, but not in Visual Basic.
