AllowTransparency Property

.NET Framework Class Library

Form..::.AllowTransparency Property

This API 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)

Syntax

Visual Basic (Declaration)

<BrowsableAttribute(False)> _
Public Property AllowTransparency As Boolean

Visual Basic (Usage)

Dim instance As Form
Dim value As Boolean

value = instance.AllowTransparency

instance.AllowTransparency = value

[BrowsableAttribute(false)]
public bool AllowTransparency { get; set; }

Visual C++

[BrowsableAttribute(false)]
public:
property bool AllowTransparency {
    bool get ();
    void set (bool value);
}

JScript

public function get AllowTransparency () : boolean
public function set AllowTransparency (value : boolean)

Property Value

Type: System..::.Boolean
true if the opacity of the form can be changed; otherwise, false.

Remarks

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.
