DataList.FooterTemplate Property

Gets or sets the template for the footer section of the DataList control.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

[TemplateContainerAttribute(typeof(DataListItem))] 
public virtual ITemplate FooterTemplate { get; set; }
/** @property */
public ITemplate get_FooterTemplate ()

/** @property */
public void set_FooterTemplate (ITemplate value)

public function get FooterTemplate () : ITemplate

public function set FooterTemplate (value : ITemplate)

Property Value

A System.Web.UI.ITemplate object that contains the template for the footer section of the DataList control. The default value is a null reference (Nothing in Visual Basic).

Use the FooterTemplate property to control the contents of the footer section. The appearance of the footer section is controlled by the FooterStyle property.

NoteNote

The ShowFooter property must be set to true for this property to be visible.

The HeaderStyle property of the DataList control inherits the style settings of the ControlStyle property. For example, if you specify a red font for the ControlStyle property, the HeaderStyle property will also have a red font. This allows you to provide a common appearance for the control by setting a single style property. You can override the inherited style settings by setting the HeaderStyle property. For example, you can specify a blue font for the HeaderStyle property, overriding the red font specified in the ControlStyle property.

To specify a template for the footer section, place the <FooterTemplate> tags between the opening and closing tags of the DataList control. You can then list the contents of the template between the opening and closing <FooterTemplate> tags.

Caution noteCaution

This control can be used to display user input, which might include malicious client script. Check any information that is sent from a client for executable script, SQL statements, or other code before displaying it in your application. You can use validation controls to verify user input before displaying the input text in a control. ASP.NET provides an input request validation feature to block script and HTML in user input. For more information, see Securing Standard ControlsHow to: Protect Against Script Exploits in a Web Application by Applying HTML Encoding to Strings, and Validating User Input in ASP.NET Web Pages.

The following code example demonstrates how to use the FooterTemplate property to control the contents of the footer section of the DataList control.
