Control.OnInit(EventArgs) Method

Definition

Raises the Init event.

C#
protected virtual void OnInit(EventArgs e);
C#
protected internal virtual void OnInit(EventArgs e);

Parameters

e
EventArgs

An EventArgs object that contains the event data.

Examples

C#
// Override the OnInit method to set _text to
// a default value if it is null.
[System.Security.Permissions.PermissionSet
    (System.Security.Permissions.SecurityAction.Demand, 
     Name="FullTrust")] 
protected override void OnInit(EventArgs e)
{
   base.OnInit(e);
   if ( _text == null)
        _text = "Here is some default text.";
}

Remarks

ASP.NET calls this method 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, call the base control's OnInit method to notify subscribers to the event.
