You can just subclass an existing control. e.g 'class MyTextBox: TextBox'. That way all existing TextBox properties are available in the Properties Window when an instance of MyTextBox is sited on a form at design time. Bit of code needed if you want custom properties to be visible in the Properties window tho.....

If you embed the Textbox in a UserControl you lose access to it's properties unless you specifically add methods to access them...


>Thanks for helping the utterly confused. The c#/.NET documentation is terrible. Perhaps I should switch to Rbase5000! Again, thanks for your help.
