Control..::.IsDisposed Property

Gets a value indicating whether the control has been disposed of.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)

Syntax

Visual Basic

<BrowsableAttribute(False)> _
Public ReadOnly Property IsDisposed As Boolean

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

Visual C++

[BrowsableAttribute(false)]
public:
property bool IsDisposed {
    bool get ();
}

[<BrowsableAttribute(false)>]
member IsDisposed : bool

Property Value

Type: System..::.Boolean
true if the control has been disposed of; otherwise, false.

Remarks

When this property returns true, the control is disposed of and can no longer be referenced as a valid Windows control. Even though the instance of a control is disposed of, it is still maintained in memory until it is removed from memory through garbage collection. When a control is disposed, you cannot call its RecreateHandle method.
