- sender
- The System.Web.UI.Page that raised the event.
- e
- An EventArgs that contains the event data.
The DataBoundControl.OnPagePreLoad(object, EventArgs) method is overridden by the System.Web.UI.WebControls.DataBoundControl class to set the BaseDataBoundControl.RequiresDataBinding property to true in cases where the HTTP request is a postback and view state is enabled but the data-bound control has not yet been bound. This scenario is common with controls such as System.Web.UI.WebControls.Wizard and System.Web.UI.WebControls.MultiView, where the visibility of the control is changed at run time.
