Begins the initialization of a System.Windows.Forms.TrackBar that is used on a form or used by another component. The initialization occurs at run time.
The vsprvs design environment uses this method to start the initialization of a component that is used on a form or used by another component. The TrackBar.EndInit method ends the initialization. Using TrackBar.BeginInit and TrackBar.EndInit methods prevents the control from being used before it is fully initialized.
