)

)

e

An EventArgs object that contains event data.

Remarks

ASP.NET calls this method to raise the Unload event. If you are developing a custom control, you can override this method in order to provide additional processing. If you override this method, call the base control's OnUnload method to notify subscribers to the event.

Examples
// Override the OnUnLoad method to set _text to
// a default value if it is null.
protected override void OnUnload(EventArgs e)
{
    base.OnUnload(e);
    if (_text == null)
        _text = "Here is some default text.";
}
' Override the OnUnLoad method to set _text to
' a default value if it is null.
Protected Overrides Sub OnUnload(ByVal e As EventArgs)
    MyBase.OnUnload(e)
    If _text Is Nothing Then
        _text = "Here is some default text."
    End If
End Sub
