Form.AllowTransparency Property

This property supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Gets or sets a value indicating whether the opacity of the form can be adjusted.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public bool AllowTransparency { get; set; }
/** @property */
public boolean get_AllowTransparency ()

/** @property */
public void set_AllowTransparency (boolean value)

public function get AllowTransparency () : boolean

public function set AllowTransparency (value : boolean)

Not applicable.

Property Value

true if the opacity of the form can be changed; otherwise, false.

This property is automatically set to true if the Opacity is changed. When the opacity of a form is set using the Opacity property, the form will layer objects on the form. If you set the AllowTransparency property to false the form will not be in layered mode which will improve the display performance of the form.
