DataList.ShowFooter Property

Gets or sets a value indicating whether the footer section is displayed in the DataList control.

[Visual Basic]
Public Overridable Property ShowFooter As Boolean
[C#]
public virtual bool ShowFooter {get; set;}
[C++]
public: __property virtual bool get_ShowFooter();
public: __property virtual void set_ShowFooter(bool);
[JScript]
public function get ShowFooter() : Boolean;
public function set ShowFooter(Boolean);

Property Value

true if the footer section is displayed; otherwise, false. The default value is true, however this property is only examined when the FooterTemplate property is not a null reference (Nothing in Visual Basic).

Remarks

Use the ShowFooter property to specify whether the footer section is displayed in the DataList control.

You can control the appearance of the footer section by setting the FooterStyle property. The contents of the footer section are controlled by the FooterTemplate property.

Example

[Visual Basic, C#] The following example demonstrates how to use the ShowFooter property to display the footer section in the DataList control.
