Visual Inheritance - How to make public inherited properties private or readonly?

[Michael.Suarez]

Let's say I create a custom component that inherits from TextBox. Then
I set the color of the textbox. Now I want it so that anyone who uses
this component can not change the color. How do i make it so that the
BackColor property is no longer able to be set (either at runtime or
design time) for my new custom text box?

You can't "hide" a base class' public member, as it would defeat the
point of polymorphism. Perhaps you can override OnBackColorChanged and
immediately set the colour back to what it was before.

Paul is right: you can't _completely_ hide the BackColor property, but
perhaps this might work for you:

private new Color BackColor
{
get { return base.BackColor; }
set { base.BackColor = value; }
}

If you just want it hidden in the property browser at design time, but
not hidden in code, you can do this:

[Browsable(false)]
public override Color BackColor
{
get { return base.BackColor; }
set { base.BackColor = value; }
}
