Hi everyone ..

I have a control NumericTextBox which is inherited from TextBox. Now, TextBox has a property named .Text which I would like to hide from the programmer.

So if the user adds a NumerictextBox to his form, there should be no option .Text

NumericTextBox myNtb = new NumericTextBox();
myNtb.Font ... works
myNtb.Size ... works
myNtb.Text ... doesn't exist


Is there any way how I can do that ?

You can't ... the only thing you could do is override the .Text method ...

There is reason for this though. If you could inherit from a class to remove functionality (i.e. externally visible items) you would break polymorphism.
