This method is used primarily by control developers.
The AdRotator.PerformSelect method for an System.Web.UI.WebControls.AdRotator object retrieves the advertisement data from the AdRotator.AdvertisementFile, and then calls the System.Web.UI.Control.OnDataBinding(EventArgs) and BaseDataBoundControl.OnDataBound(EventArgs) methods.
If the AdRotator.AdvertisementFile property is not set, then the method calls the AdRotator.PerformSelect method of the base System.Web.UI.WebControls.DataBoundControl class.
