.NET Framework Class Library

ControlAdapter..::.OnUnload Method

Overrides the OnUnload method for the associated control.

Namespace: System.Web.UI.Adapters
Assembly: System.Web (in System.Web.dll)

Syntax

Visual Basic (Declaration)

Protected Friend Overridable Sub OnUnload ( _
    e As EventArgs _
)

Visual Basic (Usage)

Dim e As EventArgs

Me.OnUnload(e)

protected internal virtual void OnUnload(
    EventArgs e
)

Visual C++

protected public:
virtual void OnUnload(
    EventArgs^ e
)

JScript

protected internal function OnUnload(
    e : EventArgs
)

Parameters

e: Type: System..::.EventArgs
An EventArgs that contains the event data.

Remarks

If there is an adapter attached to a Control object and the OnUnload method is overridden, the override method is called instead of the Control..::.OnUnload method.

Override the OnUnload method to do target-specific processing in the Unload stage of the control lifecycle. Typically, these are cleanup functions that precede disposition of the control.

Notes to Inheritors:

When you inherit from the ControlAdapter class and the adapter overrides the OnUnload method, the adapter must call the corresponding base class method, which in turn calls the Control..::.OnUnload method. If Control..::.OnUnload is not called, the Control..::.Unload event will not be raised.
