Answer 1

If you have the same member in class and it's super class, the only one way to call member from super class - using base keyword:

protected override void OnRender(EventArgs e)
{
   // do something

   base.OnRender(e);

   // just OnRender(e); will bring a StakOverFlowException
   // because it's equal to this.OnRender(e);
}
