asp:TextBox - override Text property

How do I override the开发者_JAVA技巧 TextBox property "Text" (getter) ?

According to MSDN the property is virtual so you should be able to override like so:

class MyTextBox : TextBox {
 public override string Text 
{
 get { return /* return what you wish*/; }
 set { /**/ }
}
}

You can also override one of the Render methods to have full control of generated HTML. Though perhaps you had something else in mind?
