Syntax

Visual Basic

<PersistenceModeAttribute(PersistenceMode.InnerProperty)> _
<TemplateContainerAttribute(GetType(ListViewDataItem), BindingDirection.TwoWay)> _
Public Overridable Property AlternatingItemTemplate As ITemplate


[BrowsableAttribute(false)]
[PersistenceModeAttribute(PersistenceMode.InnerProperty)]
[TemplateContainerAttribute(typeof(ListViewDataItem), BindingDirection.TwoWay)]
public virtual ITemplate AlternatingItemTemplate { get; set; }

Visual C++


[BrowsableAttribute(false)]
[PersistenceModeAttribute(PersistenceMode::InnerProperty)]
[TemplateContainerAttribute(typeof(ListViewDataItem), BindingDirection::TwoWay)]
public:
virtual property ITemplate^ AlternatingItemTemplate {
	ITemplate^ get ();
	void set (ITemplate^ value);
}


[<BrowsableAttribute(false)>]
[<PersistenceModeAttribute(PersistenceMode.InnerProperty)>]
[<TemplateContainerAttribute(typeof(ListViewDataItem), BindingDirection.TwoWay)>]
abstract AlternatingItemTemplate : ITemplate with get, set
[<BrowsableAttribute(false)>]
[<PersistenceModeAttribute(PersistenceMode.InnerProperty)>]
[<TemplateContainerAttribute(typeof(ListViewDataItem), BindingDirection.TwoWay)>]
override AlternatingItemTemplate : ITemplate with get, set

ASP.NET

<asp:ListView>
	<AlternatingItemTemplate>ITemplate</AlternatingItemTemplate>
</asp:ListView>

Property Value

Type: System.Web.UI.ITemplate
An object that contains the custom content for the alternating data item in a ListView control. The default is null, which indicates that this property is not set.

Remarks

Use the AlternatingItemTemplate property to define a custom user interface (UI) for the alternating data item. The AlternatingItemTemplate template usually contains the same controls and content as the ItemTemplate template, but with a different appearance to distinguish items.

To specify the custom template declaratively, add an AlternatingItemTemplate element inside the ListView control. Then add controls and content between the opening and closing <AlternatingItemTemplate> tags. To display the field values from the data source, use a data-binding expression. For more information, see Data-Binding Expressions Overview.

To create buttons that automatically select, delete, and edit operations, add a button control to the template. Set its CommandName property to one of the values listed in the following table.

Button type	CommandName value
Delete	"Delete"
Edit	"Edit"
Select	"Select"

Examples

The following example shows how to use the AlternatingItemTemplate template to define the style for alternating data items in a ListView control.
