	e As EventArgs _
)
'Usage
Dim e As EventArgs 

Me.OnInit(e)

An EventArgs object that contains the event data.

ASP.NET calls this method in order to raise the Init event. If you are developing a custom control, you can override this method in order to provide additional processing. If you override this method, you typically call the base control's OnInit method. If the base control's OnInit method is not called, subscribers to the event will not be notified.

' Override the OnInit method to write text to the  
' containing page if the _text property is null.
      <System.Security.Permissions.PermissionSetAttribute( _
    System.Security.Permissions.SecurityAction.Demand, Name:="FullTrust")> _       
Protected Overrides Sub OnInit(e As EventArgs)
   MyBase.OnInit(e)
   If _text Is Nothing Then
      _text = "Here is some default text." 
   End If 
End Sub 'OnInit
