ToolZone::Visible Property

Gets or sets a value that indicates whether a server control is rendered as a user interface (UI) element on the page.

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

[BindableAttribute(false)]
[BrowsableAttribute(false)]
public:
virtual property bool Visible {
	bool get () override;
	void set (bool value) override;
}
<asp:ToolZone Visible="True|False" />

Property Value

Type: System::Boolean
true if the control is visible on the page; otherwise, false.

ExceptionCondition
InvalidOperationException

The caller attempts to set the property at run time.

The ToolZone class overrides the base Visible property to consider both the value of the base property and the value of the Display property. If both property values are set to true, then the Visible property returns a value of true, and the control is visible on the page. If either property value is false, the Visible property returns a value of false, and the control is not visible.

Important noteImportant

The Visible property can only be assigned at design time in a designer, such as the Microsoft Visual Studio designer. If you attempt to set the property programmatically, an exception is thrown.

This property is not bindable in visual designers, but is bindable at runtime. For more information, see BindableAttribute.
